The development and maintenance of rotation in convective storms.

Abstract

This paper reviews the scientific background and problems posed by the existence of rotating storms, the earlier attempts at resolving the problems and the new insights provided by numerical simulation. The author considers the two separate but interacting parts of the rotational storm problem, first what produces and maintains the rotation, and second what determines the anomalous propagation of the storms. The first part was found to be relatively straight forward, though some uncertainty exists as to the relative importance of certain processes, but the second part was considerably more difficult and some fundamental questions remain unresolved.
