WHAT MAKES A THUNDERSTORM?

Moisture: cloud formation & rain

Unstable air: relatively warm air rises rapidly

Lifting: from sea breezes and mountain interaction


5/32

THREE TYPES OF

THUNDERSTORMS

Air Mass

Typical summer storms caused as Result of localized convection in an

unstable air mass

Frontal

Form right along or just ahead of a cold front

Orographic

This type of storm is the result of air that is forced upward by a mountain

THUNDERSTORM FACTS

Every thunderstorm produces lightning

Heavy rain can lead to flash flooding

Strong winds, hail, and tornadoes may be associated with

thunderstorms

Romans thought them to be battles waged by Jupiter, who hurledlightning bolts forged by Vulcan

Christian doctrine accepted the ideas ofAristotle that winds were

caused by exhalations from the Earth and that fierce storms were

the work ofGod.

THUNDERSTORM SAFETY TIPS

Go inside and stay away from windows, doors, and porches

Stay away from trees and out of boats

Avoid plumbing fixtures and contact with electrical fixtures

Stay off the phone!

TORNADOES


10/32

WHAT IS A TORNADO?

A tornado is a violently rotating column of air extending between, and

in contact with, a cloud and the surface of the earth

Tornadoes can come one at a time or in clusters

They can also vary in size, length, width, direction of travel, and

speed


11/32

HOW DO YOU MEASURE A

TORNADO?

Since February 1, 2008 tornadoes have been measured based on

the Enhanced Fujita Scale (EF)

Was implemented in place of Fujita Scale developed by Ted Fujita

in 1971

This scale helps determine the speed of a tornado from weakest

to strongest

Based on the damage they cause


12/32

THE ENHANCED FUJITA SCALE

EF 0 65 to 85 MPH

EF 1 86 to 110 MPH

EF 2 111 to 135 MPH

EF 3 136 to 165 MPH

EF 4 166 to 200 MPH

EF 5 Over 200 MPH


13/32

WHEN AND WHERE DO

TORNADOES OCCUR?

Tornadoes can occur in anystate and anytimeof year

They typically occur from March to August

The most common tornadoes are in Tornado

Alley

Tornado Alley- Arkansas, Iowa, Kansas,Louisiana, Minnesota, North Dakota, Ohio,

Oklahoma, South Dakota, and Texas states ofUSA

In India they are very rare

HURRICANES

A HURRICANE IS AN INTENSE

TROPICAL WEATHER SYSTEM THAT

HAS A WELL-DEFINED CIRCULATION

AND SUSTAINED WINDS OF 74 MPH ORHIGHER


15/32

HOW DO HURRICANES FORM?

They form when they gather heat and energy through contact withwarm ocean waters

Water evaporates from the ocean and the moisture produces a storm

They can also form when a wind pattern occurs near the surface of

the ocean and spirals inward


16/32

STORMS ASSOCIATED WITH

HURRICANES Tropical Depression

An organized of clouds and thunderstorms at low level circulation with winds at amaximum of 39 mph

Tropical Storm

An organized system of strong thunderstorms with winds between 39 to 73 mph


17/32

WHEN AND WHERE DO

HURRICANES OCCUR?

Hurricanes can occur during any time of the year

Hurricane season is from June 1st to November 30th

They can form in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico,and in the eastern Pacific Ocean


18/32

HOW DO YOU MEASURE A

HURRICANE?

Hurricanes are measured by their speed and it is split into

categories

The categories range from one to five, with one being the

weakest and five being the strongest

The classification of hurricane systems is called the Safir-

Simpson Hurricane Scale


19/32

SAFIR-SIMPSON HURRICANE

SCALE

Category One 74 to 95 MPH

Category Two 96 to 110 MPH

Category Three 111 to 130 MPH

Category Four 131 to 155 MPH

Category Five Winds greater then 155MPH

Note: Hurricanes of Category Three or above are considered majorhurricanes.


20/32

WHY DO HURRICANES HAVE

NAMES?

Hurricanes are named to help identify and keep track of storms as

they move across the ocean

Atlantic hurricanes might have Spanish, French, or English

names since they come in contact with the borders

Hurricanes are named alphabetically by the National WeatherService


21/32

In 1953, the National Weather Service began using female names

In 1979, they began to use both men and womens names
