When speed divergence occurs in the upper atmosphere, what effect does it have on cyclogenesis? A) It inhibits cyclogenesis by preventing cyclonic flow. B) It greatly enhances cyclogenesis by increasing convergence on the surface below. C) It has no impact whatsoever on the formation of mid- latitude cyclones. D) It can either inhibit or enhance cyclogenesis, depending on the surface air temperature.

Question

Quizplus · Accepted Answer

Speed divergence in the upper atmosphere enhances cyclogenesis by causing air from the surface to rise to fill the void left by the diverging air aloft. This upward motion of air leads to lower pressure at the surface, encouraging the development of a cyclone.
