Air Masses

The four types of air masses are: mT-wet and warm, mP-wet and cold, cP-dry and cold, and cT-dry warm. mT will most likely bring hurricanes because it needs wet and warm air masses. cP will most likely bring a drought because it is dry and cold. cP because Lake-Effects are snowstorms which are cold and on land. Two more air masses are: Arctic which is colder even with dewpoints and Highland which is large elevation changes over short distances.
