Question

Quizplus · Accepted Answer

An ideal source region of air masses should be physically uniform so that the air mass can maintain its characteristics as it moves away from the source region. Being located at or near the poles or the equator would result in significant temperature differences and lead to the air mass changing and losing its distinct characteristics. Having a roughly half land, half water source region could lead to differences in air temperature and humidity, also causing the air mass to lose its uniformity. Being small could limit the size and duration of the air mass.
