Abstract

The sharp depletion of attenuation of 183.31GHz signal just before the onset of Nor’wester over
Kolkata has been studied. Possible explanations of such type of variation are presented. It is concluded that this may be
taken as one possible method of forecasting of severe thunderstorms associated with Nor’wester. Physical explanations
based on the formation and dissipation mechanisms of thunderstorms are also presented.
