Study of regional heterogeneity of cloud properties during different rainfall scenarios over monsoon-dominated region

Variability in precipitation pattern is increasing even at regional scale due to advancement in global warming, which could be of higher importance in study for monsoon-dominated region such as India. Precipitation varies with region, thus the present study focuses on two types of heterogeneous regi...

Precipitation varies with region, thus the present study focuses on two types of heterogeneous regions: a region closer to the coast and an inland region.
