Air Mass and Fronts
By: Grace booth
4 Types of Air Masses
continental- formed over land (dry)
maritime- formed over water (wet)
tropical- formed somewhere warm
polar- formed over somewhere cold
continental= dry land
maritime= wet water
same humidity and temp.
large in size
constant make- up
physically bound together
cold wet, warm wet, cold dry, and warm dry.
Storms & Servere Weather-
happens when a warm and cold air both want to take over.
transpiritation, evaporation, condensation, precipitation, radiation, convection, and conduction.
Fronts and More
A front happens when two air masses meet or bumped heads together. The front is named for the air mass that took over the space. An example of a front is when a continental tropical or a dry and warm air mass is over or on top of a maritime polar air mass that is coming in, it would most likely let the the maritime tropical air mass create and take place. This is called a boundry. And a boundry is a line where two or more air masses meet called a front.
The USA isn’t a good place for air masses formation because of the frequent passing of weather disruptances.The new air mass is Continental Artic and it has almost no water and its freezing cold. K means colder air mass & W means warmer air mass. The cold air goes toward the warm and forces the warm air to move up. Warm goes over cold air, and pushes cold air back. Warm air takes over the space in warm front, cold air takes over the space cold front. A cold front is when the the air is colder than warm, it usually moves north west to south east. A stationary front is when theres a cold and warm front, then several storms happen.The symbol is a combination of the warm and cold air front symbols on a weather map.
