Project Due Today

Which ones do we need to learn?

Let it snow, let it snow, let it snow...

More Details!!!!!

All started with a little push.... What is the difference between a warm and cold front? What is the relationship between air pressure and temperature? What does a hygrometer measure? Why are winds often found between areas of high and low pressure?

Air Pressure moves from high to low

Cold Front

Stationary Front

67 72 59 78 63 Warm Front

82 ? Give an example of a temperature that the ? might be. 79 ? < 79 Cold Front

Occluded Front

What type of weather occurs when air masses meet but don’t move? Stationary Front

What type of weather comes with a cold front? Cooler and dryer

What is the map symbol for a warm front?

State with highest atmospheric pressure Idaho

Approximate atmospheric pressure of Sampson County 1018 mb

Weather moving from Michigan to Canada Warm Front

Weather moving from Illinois to Tennessee Cold Front

State with lowest atmospheric pressure Wisconsin

The winds in Missouri Very High Winds

Sudden drop in temperature, quick heavy rains, then cooler weather. The temp in El Paso is 95. The temp in LA is 79. What type of weather should El Paso expect in 2 days? Why? Sudden drop in temperature, quick heavy rains, then cooler weather.

Steady rise in temperature, drizzle or light rain, then clear skies The temp in Memphis is 84. The temp in Chicago is 67. What type of weather should Chicago expect in 2 days? Why?

L High Pressure Area H Clockwise movement Moves out of the center Anticyclone Fair weather H L

Area where there is lower pressure than surrounding areas. Low Pressure area: Area where there is lower pressure than surrounding areas.

Low Pressure Area * Moves towards center * Counterclockwise air L * Cyclone * Rising air drops water * Brings storms * Low  Lousy weather

Tornado: Severe Thunderstorm Vortex is center April – June Fujita Intensity Scale

What causes a tornado?

Larger number = greater damage

Tornado Alley

Nothing to Play With!

A Simple Overview

Hurricanes: Tropical storms affecting the south Atlantic, Caribbean, Gulf of Mexico, and sometimes east Pacific June through November (mostly after August)

Weather accompanying hurricanes: * Heavy rain * High winds * Thunderstorms * Tornadoes

Let's see that in real life....

Warm water 2. Upward Wind 3. Upper wind blows out 4. Humidity makes clouds 5. Outside winds make it grow

Extreme rise in sea level Up to 10 ft increase or more Storm Surge: Extreme rise in sea level Up to 10 ft increase or more Severe damage to coastal areas

strength of a hurricane Saffir-Simpson Scale: Measures the strength of a hurricane

So…Which is worse????? Tornado or Hurricane???

The Child Who Brings the Weather

El Nino: global wind caused by warming of Pacific Ocean bringing wet weather to US Hyperlink map to el nino video

El Nino Global Wind Pacific near Peru Large Amounts of warm water Spreads to United States

High pressure over Eastern Pacific Warm water piles up & prevents cold water from coming up to surface Low Pressure Area Inland areas get huge amounts of rain

Jet Stream: strong wind in upper atmosphere blowing west to east Hyperlink globe to video
