9.3
• A) Average occurrence of thunderstorms– Ex) January 0.4 per month
• B) Do more thunderstorms occur during the warmer or colder months in San Francisco?
• C) Think about ways to destabilize the troposphere:– Heat below or cool above– Look at climatology map to determine which
situation occurred.
9.12
• Terminal Velocity = 1750 * √(Diameter) – Units are in cm/s– Convert to mph • 6.2137*10-6 miles = 1 cm• 3600 seconds in an hour
9.15• A) Lake breeze front will be at the
boundary of clear skies and clouds. – Winds will blow perpendicular to front.
• B) Draw arrows showing wind direction AND write the wind direction of EACH location.
• C) Time of year image was taken.– How do water temperatures compare to
the surrounding land in summer, winter?– Are cumulus clouds more likely to form
over a relatively cool surface or relatively warm surface?
9.16
Match locations to descriptions • Visible satellite image,
white patches correspond to clouds
• Note location of the Appalachian Mountains.
• Image was taken in July, lakes relatively cool compared to land.
10.1abITCZ (Intertropical Convergence Zone): Elongated area that separates the trade winds in the Northern Hemisphere from their counterparts in the southern hemisphere.• The ITCZ tends to follow the sun’s direct rays• Land heats more intensely than water, less land means more even
distribution of heating.
10.2
• A) Isohyets are isopleths of precipitation.– Draw 50, 100 and 150 inch
isohyets.
• B) Use the contour map to help explain. precipitation pattern. – Prevailing low level winds
are northeast trade winds.– Precipitation pattern of the
windward vs leeward side of a mountain.
10.3• El Nino: Anomalously warm
waters in the equatorial central and eastern Pacific
• La Nina: Anomalously cold waters in the equatorial central and eastern Pacific.
• Neutral (“La Nada”): Somewhere in between, neutral or average Pacific temperatures.
