ICS18VENweatherfronts

=== Weather FrontsRead the information about Weather Fronts ===
 * The purpose of this module is to introduce air masses and weather fronts .. You will be able to describe from where they originate and some basic properties about each air mass affecting the United States. **

Answer the questions below.
>
 * 1) What happens when different types of are air masses collide? A weather front happens.
 * 2)  What are the boundaries of air mass called? Fronts.
 * 3) Define an air mass? An air mass is a large body of air that has similar temperature and moisture properties throughout.
 * 4) How large may an air mass be? It can be as large as a warm or cold front.
 * 5) What does the term moist mean. Moist means little wet but not quite.
 * 6) If an air mass is humid what does that mean? It means it is hot and damp at the same time.
 * 7) Describe an air mass which forms over Canada in terms of its temperature and moisture. It will be cold and the moisture will be high because it will be very snowy.
 * 8) Describe an air mass that forms over a desert in terms of its temperature and moisture. It will be hot and the moisture will be very little because it will be dry outside.
 * 9) Describe an air mass that forms over water in Gulf of Mexico in terms of its temperature and moisture. It will be warm enough to form a hurricane but it will have little moisture.
 * 10) In the area of the Unites states, which way do cold air masses move? (North or South) They move South.
 * 11) In the area of the Unites states which way do warm air masses move? They move North.
 * 12) Why are Canadian air masses considered to be dry air masses? Because it has no water below it.
 * 13) What happens when a warm humid air mass meat a cold dry air mass? It becomes a warm front.
 * 14) Why can cold air masses from Canada make it all the way down to the Gulf of Mexico? It becomes a cold front.
 * 15) What is a front? A front is boundaries between air masses.
 * 16) What typically happens when two different types of fronts collide? It becomes a hurricane.
 * 17) What are the three types of fronts? 1. Cold Front. 2. Warm front. 3.Stationary front.
 * 18) Describe the temperature of the air behind a cold front. A air behind a cold front is cold.
 * 1) Looking at the diagram above, which state has a temperature of 380F? Colorada
 * 2) Looking at the diagram above, which state has a temperature of 550F? Alabama
 * 3) Looking at the diagram above, what would you expect the temperature of Illinois to be in three days? EXPLAIN! I think it would be 56 because the cold front is heading that way.
 * 4) How does the temperature of an area change as a cold front passes? It goes down.
 * 5) What does precipitation mean? Precipitation is rain.
 * 6) What type of precipitation occurs when a cold front passes? Snow or hail.
 * 7) Describe the type of air behind a warm front? It gets warmer.
 * 8)  In which direction do warm fronts typically move. WEST.
 * 9) What type of precipitation usually occurs when a warm front passes by. Just warm rain.
 * 10) Label the two fronts on the diagram below: Cold front and warm front.
 * 1) How is cold front diagrammed? When the cold air moves into the warm air.
 * 2) How is a warm front diagrammed? When the warm air goes to the low pressure then it keeps rotating counterclockwise.
 * 3) What is a stationary front? A stationary front are pretty much just that stationary.
 * 1) How is a stationary front diagrammed? It is diagrammed because it has a warm front and stationary front s have warm fronts in them.
 * 2) When warm air contacts cold air, which air mass typically rises above the other? MT.
 * 3) Which of the following is a diagram of cold front and which is the warm front? The first one is warm front the second one is a cold front.

On the diagram below: On the diagram below:
 * 1) How are cold fronts diagrammed? The blue keeps going into the red and that is a cold front.
 * 2)  How many cold front are there on the diagram? There are three.
 * 3) In which direction is the front over Washington and Oregon traveling? How do you know? Cold front because the blue is going into the red.
 * 4) In which direction is the front over North Carolina traveling? Southeast.
 * 1) How is the warm front diagrammed? The red.
 * 2) In which direction is the warm front traveling? South.
 * 3) What do you call the front that is over the middle of Canada? A cold front.

 * 1) If it is snowing in Great Neck, what type of air mass must be present? Cp
 * 2)  If its very hot in October in Great Neck, what type of air mass must be present? Ct
 * 3) Assuming a warm front is moving into the area, there is a stagnant (non-moving) cold air mass around Great Neck, what type of precipitation might we expect? How long might it last? It might last until it starts moving again and it might be tropical.
