Apparent geographic and atmospheric influences on raindrop sizes and rainfall kinetic energy

Research output: Contribution to journalArticlepeer-review

Abstract

Median raindrop diameters in North Carolina, New Jersey, and the Marshall Islands tended to be less than those observed in Panama, Indonesia, Washington, D.C., and Zimbabwe. Calculated rainfall kinetic energies for Panama and Indonesia were within 10% of that predicted by the universal soil loss equation (USLE) rainfall energy equation. Calculated rainfall energies for New Jersey, the Marshall Islands, and North Carolina ranged from 5% to 28% less than that predicted by the USLE rainfall energy equation. Increasing the rainfall energy estimate by 7% for each 1000 m (3280 feet) of elevation above sea level is suggested to account for increased raindrop velocity under reduced atmospheric pressure. -from Author
