1. Weather: Storms

2. Storms Occur in Wave Cyclones
Always in LOW Pressure Systems
USUALLY with the COLD FRONT

3. Cold Front Action Warm, humid air is rises and cools
Condensation forms
CLOUDS
A storm is BORN!
The higher the air
rises, the more severe
the storm!

6. Thunderstorms At COLD FRONTS with intense LOW PRESSURE
CUMULONIMBUS CLOUD
At COLD FRONTS with
intense LOW PRESSURE
Warm air rises high…
up to 40,000ft!
Heavy rain, lightning,
high winds, hail possible

7. Tornado! With SEVERE thunderstorms… EXTREME LOW PRESSURE
Tornado In Action
With SEVERE thunderstorms…
EXTREME LOW PRESSURE
Funnel Cloud attached to
a cumulonimbus cloud
Winds mph!
About 300 ft across at
ground level

8. Hurricane LARGE area of VERY LOW PRESSURE Form over TROPICAL
Katrina- 2005
LARGE area of VERY
LOW PRESSURE
Form over TROPICAL
oceans (warm&humid)
travel north
Strong winds, heavy rain,
large waves called storm
surge
Atlantic Hurricane Season:
June 1- October 30

9. HURRICANE’s Other Names
ATLANTIC OCEAN – HURRICANE
PACIFIC OCEAN –
TROPICAL CYCLONE
INDIAN OCEAN – TYPHOONS
ALL THE SAME THING!!

condensation occurs,
clouds form
Storm intensifies!!
