Effects of Electric Forces on Rain Formation Process in Tropical Clouds

Abstract

Precipitation, a product of complex cloud microphysical processes in the Earth s atmosphere has a profound influence on the Earth s geosphere as well as the biosphere. The quantity and intensity of precipitation at the Earth s surface influences the hydrological cycle as well as the social and economic activity of human. Precipitation also influences the atmospheric general circulations through redistribution of latent heat. The microphysical as well as dynamical properties of clouds, determine their role in the global radiative budget and precipitation formation. Historically persistent attempts have been made for accurate estimation of intensity and quantity of precipitation through multidimensional observational network, and also using numerical weather/climate prediction models. It has been recognized that for accurate estimation of rainfall with weather radar, it is very important to understand the prevailing cloud microphysical processes which lead to the raindrops. Numerous simulation studies have also reported that to improve the simulation and forecast of intensity of rainfall, proper representation of raindrop size distribution (RDSD), a parameter which reflects the prevailing in-cloud microphysical processes is of profound importance newline
