Question

Quizplus · Accepted Answer

The difference between annual precipitation and evaporation potential, known as the water balance, is the most accurate measure of the wetness or dryness of a region. Total annual precipitation and percentage of precipitation during summer months can be misleading as regions with high total annual precipitation may still experience drought if there is large evaporation potential, and regions with low total annual precipitation may not experience drought if evaporation potential is also low. Mean annual temperature is not a reliable indicator of wetness or dryness.
