The Southern California Operating Area near-coastal zone study was

* prepared by direction of the Commander, Naval Oceanography Command and theOfficial in Charge, Naval Oceanography Command Detachment, Asheville, North

Carolina. Work was performed by the National Climatic Data Center (NCDC).

Geographical and Data Coverage

This study covers the southern California area (240 N to 370 N; 115 0 W to125 0W) with the greatest emphasis being placed on the marine areas (see Fig.

1). Surface marine statistics are presented on monthly charts in the form of

graphs, tables and isopleth maps. Land station data appear graphically and inStation Climatic Summary tables in the last section of the publication. The

* marine data were machine plotted by one-degree quadrangle and then handanalyzed. The graphs and tables for the marine areas are also presented by

one-degree quadrangles (visibility, wave heights, and wind roses). Thesegraphs and tables represent the objective compilation of available data; the

data were not adjusted for suspected biases (low observation count, heavyweighting of observations during a short time interval, biases in coding of

observations from various source decks, etc.), and differences may be foundwhen comparing the graphic data with isopleth analyses. The total number of

observations for a given one-degree square should always be considered wheninterpreting the data, as there may be an insufficient number to permitrepresentative statistics.

Just over one million surface marine observations were used in computing

the statistics. These data, taken from NCDC's Tape Data Family 11 (TDF-II),were collected by ships of various registry traveling in the study area. Some

observations were collected as early as 1854. Data for this study wereobtained from the earliest available period through 1979. The bulk of theobservations are from the last 30 years, which is significant because more

recent observations contain more elements than pre-1948 reports. The density

of observations is greatest along the major shipping routes; in this area majortraffic moves north-south just off the coast, and along the Asian routes to and

from Los Angeles and San Francisco.

The mean sea current charts were extracted from the Department of

Transportation, Coast Guard Oceanographic Unit Technical Report 82-2, PacificArea Current Charts.

Physical Features

In California, north of the Los Angeles Basin, basically two mountainranges parallel the coast. The Coast Ranges on the west generally run no more

than 50 miles from the sea to the crest of the mountains, while farther inland* to the east run the Sierra Nevada. In between the southern extent of these two

mountain ranges lies the San Joaquin Valley, the drainage basin that empties

into San Francisco Bay. The melt water from the High Sierras has provided the

*necessary irrigation water to make the San Joaquin Valley a highly productive

farm area. [J

In southern California there are a number of smaller mountain ranges. TheSan Gabriel and San Bernardino ranges are the most extensive and are basicallylocated to the east and southeast of Los Angeles. South of the San Bernardino "

range lie the San Jacinto mountains and farther south, the Santa Rosa range.

The Santa Ana range parallels the coast to the west of the San Bernardino and es

San Jacinto mountains. r

To the east of the mountains in southern California lies the desert regionwhich includes Death Valley (just east of the southern end of the SierraNevada). The lowest point in the U. S. is found at 282 feet below sea level inDeath Valley, which is just 85 miles from the highest peak within the

" contiguous U. S., Mt. Whitney (southern end of the Sierra Nevada) at 14,494feet above sea level.

The southern portion of this California Desert region is generally

referred to as the Salton Sea - Sonoran Desert, with its northern portiondesignated as the Mohave Desert. East of the Santa Rosa mountains lies the

. Salton Sea Basin with the surface level of the lake below sea level. Thisregion is a cut-off remnant of the Gulf of California. South of the lake lies

the area which has become known as the Imperial Valley because irrigation hasmade it one of the most productive agricultural regions in the western UnitedStates. This region is sparsely settled with El Centro being the major

population center.

The California coastline, unlike the Atlantic coast, does not have anyextensive coastal plains but rather is characterized by miles of steep seacliffs or rock terraces. Yet with this type of shoreline topography, none of

the California bays, except for San Francisco Bay, provide a safe harbor forshipping. San Francisco Bay, however, happens to be one of the best harbors

in the world.

The continental shelf off southern California extends westward forapproximately 150 miles before reaching the escarpment (continental slope) thatdrops down to the deep ocean basin. This shelf differs from the gentle slopeoff Florida; instead of the smooth under-surface there are a number of islandsprotruding above the surface and a number of banks just below the surface

(Shepard, 1963). Reference Fig. 1 for the depth contours.

A cold ocean current runs from north to south along the California coast.

The associated upwelling is important to commercial fishing as it producesenough organic nutrients to support large stocks of commercially importantfish. Changes in the large-scale atmospheric circulation offshore, in responseto both thermal and wind forcing processes, may cause the near-shore current to

alter its normal pattern and thus affect the fishing as well as the California

climate (Nelson and Husby, 1983).

Climate

The southern California climate is best described as a Mediterranean-typeclimate where the summers are cool and the winters are warm, especially whencompared to other locales of the same general latitude. Rainfall is seasonal

. with most of it falling during the winter. Both San Diego and Long Beach

average near 10 inches of annual precipitation, most of it occurring betweenNovember and April. The remaining 6-month totals average less than one inch.

* See Fig. 5 for the monthly means of precipitation and temperature forselected locations. Thunderstorms occur but are rather rare; San Diegoaverages about 3 per year. The mountains to the east occasionally get a few

more thunderstorms, but as indicated in Fig. 2 (mean number of annualthunderstorms), most of the western half of California get less than 5 peryear. A large number of the summer monthly precipitation totals at San Diegoshow a trace but a rare tropical storm will sometimes move into the region and

produce monthly values in excess of 2 inches. Heavy thunderstorms can also

produce record rainfalls. On August 12, 1981, at Campo in San Diego County, a

thunderstorm rained 16.10 inches of which 11.50 inches fell in 80 minutes. Ingeneral the mountains of southern California receive between 30 and 40 inchesper year, the coastal plains 10 to 15, and the desert regions 2 to 5 inches.

The dominant feature which controls the southern California weather is thesemi-permanent North Pacific subtropical high. During summer, the high becomesmore intense and moves farther north thereby restricting the few storms thatdevelop during this season to storm tracks far to the north. With winter, thesubtropical high is less intense and retreats somewhat southward and, thus,allows more storm tracks to penetrate into southern California. See Fig. 3 forthe January and July mean pressure pattern.

Southern California coastal areas are occasionally affected, primarilyduring the fall and winter, by a foehn-type wind known as a Santa Ana. The drynortheasterly winds typically have speeds of 15 to 25 mph and relative

% humidities of 30 percent or less, and the accompanying temperatures areV. generally at least 50F warmer than the monthly average (de Violini, 1974). The

effects of these winds have been felt between Santa Barbara and San Diego andas far east as the mountains and as far west as 50 miles seaward. In areasdownwind of canyons and mountain passes these Santa Ana winds can be especiallysevere. For example, on Dec. 20, 1977, Santa Ana winds of up to 90 mph roaredthrough San Diego County downing power lines, causing serious crop damage, andfanning brush fires. The strong winds snapped a power pole on Vandenberg AFBand started a fire that swept through more than 10,000 acres. The tragic fireclaimed the lives of the Base Commander and two other base officials. Inanother example, the San Diego WSO reported easterly winds of 60-70 mph in thepass east of Alpine on Jan. 9, 1982.

In a majority of instances the Santa Ana winds will follow the passage ofa cold front. They may start within a few minutes of passage or up to 48 hours

-.2. afterwards. Behind the front a large mass of cold air will push in over theGreat Basin. As the high continues to build over this region, nighttimecooling helps to intensify the surface pressure until this cold dense airbegins to push through the mountain valleys and continues on its journey to thesea. As the air descends it is heated by compression to generally between 20and 250 F by the time it reaches sea level. The intensity and duration of theSanta Ana winds depends upon the pressure gradient between the Great Basin andsouthern California, the strength of the northerly winds aloft, and thetemperature of the cold high pressure air mass. As the air descends and iswarmed through compression, it is capable of taking on much more water vapor;for this reason the relative humidity is low during a Santa Ana.

Dangers to aircraft caused by Santa Ana winds are low level turbulence aswell as occasional moderate to severe turbulence aloft. For vehicular trafficthe hazards are greatest for those with large surface areas, but any vehiclecan be blown into oncoming traffic or off the side of the road. Large signs,billboards, and trees are occasionally blown over and large windows blown out.But the greatest hazard is the drying effect on the grass and bushes ofsouthern California which increases the likelihood of fires. The worst firesof this type in the state have all occurred under conditions of Santa Anawinds.

For example, in September 1970, from the 25th through the 29th, Santa Anawinds brought high temperatures, low humidities, and strong winds therebycreating an explosive fire potential. More than 500,000 acres were burned-over

in Los Angeles, Ventura, Kern, Orange, San Diego, and San Bernardino counties.

Some 500 homes were destroyed, along with more than 500 other structures,including at least four churches. Also, 20 firemen were injured.

The combination of the cold ocean current and the semi-permanentsubtropical high produces stratus on nearly a daily basis during the summeralong the southern California coast. An inversion is created as long as the

* cold layer of marine air is maintained beneath the warm dry air of thesubtropical high. The stratus clouds generally form during the night and early

r.+ morning and frequently push into the coastal valleys and foothills. It is lesslikely that the clouds will penetrate farther inland. If so, they will arrivelater, and will burn off earlier. Most of the coastal areas clear up duringthe morning giving generally comfortable sunny afternoons. Fog does formoccasionally during the summer but is much more frequent during the winterseason. Early morning fog forms mostly because of radiational cooling and coolair drainage from the nearby hills.

Rarely a tropical storm will move into southern California bringing mostlyheavy rains. Fig. 4 shows the annual 12-hourly movements of tropical cyclonecenters with tropical storm intensity or greater (wind speed estimated > 34knots). For example, during Sept. 10-11, 1976, the worst tropical storm in 37years moved into southern California causing record rains and tremendous cropdamage. The hardest hit area was the small desert community of Ocatillo inImperial County. Flood waters tore homes from their foundations and leftnearly 70 percent of the town buried in sand which measured up to 10 feet indepth.

In just under a year the unlikely event of a second tropical stormoccurred in the same general region of southern California. On Aug. 17, 1977,tropical storm Doreen dumped 4.5 inches of rain within several hours in the

district. It tore off parts of one roof, downed several trees, broke glass,

and generally scattered debris along its path. A month later in San Diego, onJan. 18, 1979, a tornado touched down, traveled 100 yards before lifting off,and touched down again 1/2 mile farther east where it again traveled 100 yards Ibefore lifting off and dissipating. In both examples it generally only brokeglass and scattered debris.

In southern California the temperatures are very hospitable, especially

along the coastal regions. A small daily temperature range, in conjunctionwith a comparatively small annual temperature range, has helped to make the

southern California coastal region a major population center. For example, at

San Diego the highest monthly mean daily maximum, 770 F, occurs in August. For

* the same month the mean daily minimum runs a very comfortable 640 F. Monthly

mean temperatures at San Diego range from 55°F in January to 71°F in August.

Mean daily maximum and minimum temperatures for January run 650 F and 460 F,

respectively. Between 1941 and 1981 the record highest temperature was 1110F(Sep. 1963) and the lowest 290 F (Jan. 1949). As one moves inland away frt .1emarine influence the temperature variations increase. For example, El

Centro in the Imperial Valley the normal maximum and minimum temperature (orJanuary are 691F and 380 F, and for July 1080 F and 740 F, respectively. Ho er,

these temperatures are conducive to a very equable climatic regime. I 5

Marine Climatological Elements

Precipitation

Of the elements recorded in the marine data base, precipitation is one ofthose most subject to error in both the way it is observed and the way it isinterpreted. In many areas of the world, especially in more recent years,ships try to avoid foul weather and thus bias the data towards fairweather.

The percent frequency of present weather observations reportingprecipitation reaches a maximum during the winter months and minimum during thesummer as previously discussed pertaining to land station data. During Januarythe percent frequency of precipitation over the southern California operatingmarine area ranges from less than 3 percent off Baja, California, to 10 percent .

at Monterey Bay. For the summer season frequencies run from less than I to 3percent. The pattern shows slightly higher occurrences seaward. Thunderstormsoccur so infrequently that these charts were not included in this publication.Fig. 2 shows fewer than 5 thunderstorms a year being reported at most landstations throughout the coastal regions of southern California, and based onthe marine observations even fewer occur at sea.

Tropical Cyclones

Tropical cyclones are not much of a menace to the Southern CaliforniaOperating Area as indicated by the tropical cyclone rose (Fig. 4). However,south of Baja lies the world's most concentrated Tropical Cyclone area; theaverage annual number of tropical cyclones is about six per five-degree square(Fig. 6).

Air Temperature

Air temperature is one of the elements most frequently observed bymariners. Due to instrument exposure on many ships, the heating effects of aship's structure tend to produce readings that are higher than the actualambient air temperature. This doesn't appear to be as much of a problem in theSouthern California Operating Area as it is in the tropical regions of theworld.

Isotherm patterns for air temperature are relatively zonal during thewinter season averaging between the mid-fifties at the northern end of thestudy area to the mid-sixties at the southern end. The winter pattern showslittle influence of the cold California coastal current. By spring, however,the isotherms begin to follow along the path of the current showing its coolingeffects relative to the areas on either side. By September, the warmest month,mean temperatures range from 60°F near Monterey Bay to the low seventies offBaja and across the southern end of the study area. At 330N, between San Diegoand Oceanside, mean temperatures in September run from 68°F just off the coastto under 650F just west of San Clemente Island, showing the effects of theupwelling.

° Sea Surface Temperature

Sea surface temperatures are recorded with a fairly high frequency inmarine observations. Two principal methods for sampling are used: intake

Mean sea temperature isotherm patterns are very similar to those of airtemperature. The sea temperature isotherms illustrate the cold Californiacurrent a little more than those of air temperature during the winter but theisotherms are generally still fairly zonal. Summertime patterns, however,clearly depict the cold current. Mean sea temperatures during February, thecoldest month, range from 540F near Monterey Bay to 660F at the southern extentof the study area. August brings the warmest sea temperatures with meansranging from just under 590F in Monterey Bay to over 750F in thesoutheastern-most portion of the study area. A warm region lies off the coastof San Diego, averaging 690F, while farther west at the same latitudetemperatures drop off to near 630F.

Surface Winds

The surface wind is one of the most commonly observed elements. Many ofthe observations from the NCDC data base are visual observations based on theroughness of the sea. In recent years more ships acquired anemometers andreported measured winds. Prior to 1963 many of the wind speeds were recordedin the Beaufort scale; however, such estimates have proven to be quite reliable

and can be used with a high degree of confidence. Five sets of wind speedisopleths are presented: mean scalar speed, the percent frequency of winds

less than 11 knots, 11 to 21 knots, 22 to 33 knots, and greater than or equal, y to 34 knots. Also included are wind roses by one-degree square.

Gale force winds (> 34 knots) occur less than 5 percent of the time, basedon the marine observations taken within the Southern California Operating Area.Strong winds occasionally occur with a cold frontal passage or during a SantaAna. With cold fronts not being that frequent and the Santa Ana winds onlyrarely reaching as far as 50 miles out to sea, the mariner rarely observesstrong winds within this area. The sea breeze effect can be rather strong onland during the day because of the strong differential heating between thedesert regions and the sea. The opposite effect, the land breeze, is not asstrong over the sea at night since the differential heating is not nearly as

a' strong. Both Santa Ana winds and the land breeze are near-coastal phenomena;*therefore, neither significantly effect the wind statistics for a large portion

of the Southern California Operating Area.

The wind regime across this region varies little from month-to-month orseason-to-season. Mean scalar winds from Los Angeles to San Diego average 7 to10 knots throughout the year. Slightly stronger winds (10-15 knots) areencountered along the coast north of Point Arguello. West of the ChannelIslands, monthly scalar mean wind speeds are from 10 to 16 knots.

Wind speeds from 11 to 21 knots generally occur 40 to 50 percent of thetime over the open water. They are less frequent east of the Channel Islandswhere frequencies run 15 to 30 percent.

Higher threshold winds (22-33 kts) are most frequent during March andApril, occurring more than 5 percent of the time, except in the Gulf of SantaCatalina. Frequencies as high as 15 to 25 percent are generally found in theregions to the west and northwest of the Channel Islands.

Visibilities are difficult to measure at sea because of the lack ofreference points. Climatically, many low visibility observations are probablymissed because the mate is too busy with other duties (fair weather bias).However, the coarseness of the visibility code intervals tends to minimize theproblem, permitting the summarized data to be relatively consistent. Thevisibility tables that are presented by one-degree square show that the openocean areas have a high frequency of good visibilities. In all months,frequencies for 5 miles or better run 90 percent or greater for the open sea.For the near coastal-zone frequencies for 5 miles or better generally run near

-? *70 percent tc 80 percent during the summer and near 90 percent during thewinter, just slightly less than the open sea winter visibilities. These

" visibility table figures are somewhat contradictory to the observations takenat Los Angeles and San Diego. Although fog is observed every month it is leastobserved during the summer with the fall and winter being the foggiest. Thisis not the pattern one sees when checking the visibility tables. This is mostprobably due to two reasons: (1) ship personnel are generally very busy withother tasks when entering and leaving port; therefore, weather observations aregenerally not taken in close to shore, and (2) if the weather is poor, forinstance in fog, the ship will delay its departure or entrance into a congestedport (fair weather bias).

Clouds

A survey of the cloud data (total and low cloud amounts) within the marinedata base shows a number of total clouds reports significantly greater than lowcloud amounts. This is because many of the early marine observations containonly total cloud amounts. For the two presentations (total cloud amount < 2/8

Wand low cloud amounts > 5/8) only those observations reporting both total andlow cloud amounts were summarized. This helps eliminate problems introduced asa result of different size data bases (N-count). The use of satellite datahelps bolster confidence in the total cloud analyses because they show fairlyclose agreement with those summaries (U. S. Department of Commerce and UnitedStates Air Force, 1971).

During the winter months, the percent frequency of low clouds greater thanor equal to 5 oktas is just under 30 percent along the coast and 50 to 60percent out over the open water. In the summer, they increase to near 60percent along the coast and 70 to 80 percent over the open water.

Total clouds less than or equal to 2 oktas generally run 40 to 50 percentalong the coast during the winter and 20 to 30 percent in the summer.Offshore, over open water, frequencies are usually found in the 15 to 30percent range during the winter and in the 10 to 20 percent range during

summer. For more detail one should make use of the isopleth charts.

Ceiling and Visibility

Aircraft-type ceilings are not available from marine observations. Theceilings are estimated from the height of the lowest cloud when low cloudscover more than half the sky. When the sky is totally obscured by rain, fog, -

dust, or other phenomena, the total obscuration is considered a ceiling with aheight of zero. Mid-range ceiling and visibility charts (ceiling less than1000 feet and/or visibility less than 5 nautical miles; ceiling less than 8000feet and/or visibility less than 10 nautical miles) and low range ceiling and

visibility charts (ceilings less than 300 feet and/or visibility less than 1nautical mile; ceiling less than 600 feet and/or visibility less than 2nautical miles) are presented. Ceilings less than 8000 feet and/orvisibilities less than 10 nautical miles are observed approximately 50 percentof the time during the winter and near 80 percent during the summer. Incomparing the next threshold (<1000 feet and/or 5 nautical miles), frequenciesaverage 15 to 20 percent during the winter and 20 to 30 percent during thesummer. In the low range, there are only slight differences between the twolow range threshold categories. When conditions deteriorate enough to fallinto the higher of the low categories (< 600 feet and/or 2 nautical miles) theyoften continue their deterioration until they reach the lower category (< 300feet and/or 1 nautical mile). During the winter, observations fall into the

low range 5 to 7 percent of the time and in the summer 15 to 20 percent of thetime. Usually only a few percentage points separate the two low rangecategories.

Wave Heights

Wave heights have been recorded in a consistent quantitative code onlysince the late 1940's. The reluctance of many observers to take waveobservations in the earlier years and the difficulty in estimating waves, *especially in confused seas, make wave observations one of the least commonlyobserved elements. They are also subject to biases. (Quayle, 1980) Generally

, .•. . .-. .. .. -..- .. j.- ...-..-.. ... . ....,= . . ... . . .... ....- .. -•

the heights are too low, the periods too short, and the sea-swelldiscrimination poor. The data in this study have not been adjusted for the

suspected biases other than being processed through a quality control procedurewhere an internal check was made between wind speed and sea height. The data

were also arrayed and apparent erroneous outliers were deleted in both the seaand swell data. Wave height presentations include isopleth maps showing

percent frequencies of wave heights > 3 feet and > 8 feet. In addition, waveheight tables by one- degree quadrangle show frequencies by six wave heightcategories. In these presentations, the higher of the sea or swell wasselected for summarization. If heights are equal, the wave with the longerperiod is selected.

As with the wind regime, the mean monthly wave regime has little annualvariation. Frequencies of wave heights of 3 feet or greater are observed 80 to90 percent of the time in the open water and 40 to 50 percent of the time inthe Gulf of Santa Catalina. For wave heights of 8 feet or greater there is asmall decrease in the number reported during the summer in comparison towinter. Percent frequencies of wave heights > 8 feet in general run from under

5 percent in the Gulf of Santa Catalina to i07to 20 percent west and south of

the Channel Islands and 25 to 35 percent northwest of Point Arguello.

Ocean Currents

The mean sea current charts, extracted from the Coast Guard Oceanographic

Unit Technical Report 82-2, give mean geostropic currents computed from dynamicheight anomalies and contain none of the wind current components that areinherent in the set and drift method of deriving sea current data. If one

wishes to make drift forecasts the sea currents must be combined vectoriallywith a wind current calculation for the time and area of interest. Local wind

current data can be calculated based on a method found in the OceanographicUnit Technical Report 78-2 (U. S. Coast Guard Oceanographic Unit, Building159-E Navy Yard Annex, Washington, D.C. 20593).

Summary

In general, the weather across the Southern California Operating Area isrelatively equable. The unpleasant variations are generally the coastal fog

and rains during fall and winter and the low clouds and air pollution during

spring and summer. However, rare anomalies, such as the Santa Ana winds,

thunderstorms, tornadoes, or tropical storms do occur. An anomalous winter,such as the 82-83 season where a succession of Pacific storms continuallybattered the west coast with strong winds, heavy rains and high seas (which

produced some of the worst weather-related damage in history) is always apossibility. This anomalous west coast winter might possibly be related to theEl Nino which began in 1982 and was at its peak during the 82-83 NorthernHemisphere winter. Correlations between indices of the El Nino and certainNorth American meteorological variables are statistically significant tor theNorthern Hemisphere winter (Philander, 1983).

An area such as southern California, which is renowned ior its pleasantand congenial climate, can have weather events that are within the normal rangeof activity but which have a high potential for devaslitiot.. cliatologicalsummaries, such as this, help delineate those possibilities.
