Air Masses

1. Their are cT, cP, mT, and mP. m stands for maritime, c stnds for continental, P stands for polar, and T stands for tropical.
2. I think mT air masses bring hurricanes.
3. I think cT air masses bring droughts.
4. I think cP air masses bring lake-effect snowstorms.
5. There also are arctic and highland. Arctic comes from northern Canada. This air often forms when a high pressure area becomes nearly stationary over Eastern Alaska and the Yukon. And highland occurs in regions with large elevation changes over short distance. It is not a source region for one particular type of air mass. Since highland climates are in an elevated terrain, they can promote dryness in the interior of the highland climate. When air masses enter a highland climate they modify due to these elevation changes.
