Air Mass is a uniform body of air that has similar temperature and moisture content. There are four different kinds of air masses: Maritime Tropical form over warm oceans. Continental Tropical form over land and are warm. Continental Polar form over land and are cold. Maritime Polar form over cold oceans.

Air Masses Meet

When the sun heats the surface of the earth, the air near the surface is warmed and it begins to rise. Colder air then rushes in to replace the rising warm air. Because water responds to hot and cold temperatures in the exact same way the air does, the movements of warm and cool air may be demonstrated using hot and cold water. To make this project put a drop of food coloring into one of the two glasses and fill it with hot water. Fill the second glass with cold water. Put the cold glass in either a sink or large bowl. Put a piece of cardboard over the top of the glass holding the hot water. Turn the glass upside down, pressing down on the cardboard to keep the water from pouring or overflowing. Put the glass of hot water on top of the glass of cold water; the openings of the glass should be on top of each other, separate only by the sheet of cardboard. Then slowly remove the cardboard from between the two glasses. —Preceding unsigned comment added by 72.148.0.81 (talk) 19:46, 13 October 2007 (UTC)

[edit] 4 main types?

There is a Continental Arctic, the coldest air mass other than the 4 listed --Natasha2006 15:34, 17 October 2007 (UTC)
