Aerosol Variability and Its Impact on Cloud-Precipitation Interaction in Urban Areas of Maharashtra, India

Aerosol-cloud-precipitation interactions in seven non-attainment cities with elevated particulate matter levels is studied. Aerosol mode analysis indicates the dominance of fine particulate matter. AOD levels are notably higher in Delhi, while other cities exhibit AOD levels with no significant trends. Correlations between Precipitation (PRCP) and Cloud Effective Radius (CER) suggest the second indirect effect. A random forest model highlights AOD and Cloud Fraction (CF) as key predictors of PRCP, with meteorological factors dominating Delhi. The study underscores the complexity and spatiotemporal variability of aerosol-cloud-precipitation interactions, necessitating a multifaceted approach for a comprehensive understanding.
