Impacts of Aerosol Orographic Precipitation Interaction Associated with Western Disturbances over India Using Satellite Observations

Western disturbances (WDs) develop as extra-tropical low-pressure systems over the Mediterranean and lose their frontal structure they move eastward toward India. The effect of aerosols on microphysical characteristics precipitation clouds associated with WDs in February 2016 was investigated west coast India adjacent Arabian region. This research highly depends era interim reanalysis ensemble back-trajectory simulation. Among WD event’s pre-mature mature phases, warm humid prevailing winds were observed, resulting substantial aerosol movement. Compared to ERA-Interim thirty-year mean climatology, temperature simulations higher during dissipating phase through phase. During dispersing phase, confluence easterly westerly evident study region’s eastern northeastern areas. Over northern sections country, there a quantity high ratios water-vapor mixing significant level humidity. Precipitation occurred among parts area between phases. All forecasts overstated Odisha, Gujarat, Maharashtra, West Bengal, whereas model underestimated it Kerala, Karnataka, Konkan, Goa. Between phases regions where rainfall cloud fraction (CF) value vertical integration moderate high. relationship optical depth (AOD) showed stimulating presence aerosols, which results enhanced rain
