摘要

In this study, linkage between changing characteristics of precipitation extremes and cloud covers over Central India is explored during summer monsoon period using Satellite data (1998-2015). This is a first attempt to relate the changes in cloud cover to the changes in precipitation extremes. Non-rainy cirrus clouds are excluded from this study. Results show that heavy rainfall ( = 60 mm/day) is associated with cold cloud tops (Tb = 5.220 K) while moderate rainfall ( 60 mm/day and = 20 mm) occurs mostly with middle clouds (Tb 220 K and = 245K). Low level clouds (Tb 245 K) are responsible for light rainfall ( 20 mm/day). Increases in top 20%, 10%, 5% and 1% heavy precipitation relate well with the increases in very deep convective, deep convective and convective cloud cover. Among these relations, increase in top 5% heavy precipitation relates best with increase in very deep convective cloud cover. Decrease in bottom 30% low precipitation relates with decrease in low level cloud cover. The results reported in this study fit into the framework of how weather extremes respond to climate change.
