Impact of Aerosols on Precipitation over Western Ghats

Abstract

One of the significant mountain region running parallel to India s west coast is the Western Ghats. Normally, this area receives three times rainfall because it is nearly vertical to the low-level jet stream. But this rainfall is affected in recent years due to the aerosol particles. Aerosols, tiny particles present in the atmosphere, play crucial roles in weather and climate. It is generated primarily as solid particles, for example, Asian dust, Saharan dust, sea salt, or soot. Aerosols can have a variety of impacts (e.g., direct and indirect effects) on the atmosphere, which can lead to the earth s radiation budget. It has a strong impact on the formation of clouds and precipitation processes also. The aerosol change-based influences are considered as the main factor related to air pollution controlling and environmental regulations. Hence, this article mainly concentrates on climate influences related to global aerosol variation. In this paper, recent aerosol behaviors and their impacts on the Western coastal (WG) region of India from 2014 to 2017 are analyzed. From the analysis, we observed that the precipitation is increased in the West Coast region.
