Abstract

Most of Rajasthan, being an area of less annual rainfall, soil and topography adhered to the condition, sudden, rapid and exceedingly heavy rains for even a day or two, in a localized area can cause severe floods with natural calamity of very high order: Study of some of these situations in the Indian summer monsoon field reveals, that, fractional superimposition and therefore fractional accentuation of pre-existing lower troposphere cyclonic vortices by upper anticyclonic shear zones formed out of propagation and amplification of an upper westerly and an easterly wave, in close proximity  is  actually responsible for such exceeding  heavy falls in meso or small areas.
