Studying Himalayan Snow - Indian Monsoon Relationship by Some LULCC Sensitivity Experiments in REGCM4.0
This study re-examines the relationship between Himalayan snow and Indian monsoon and impact of land surface degradation due to depletion of Himalayan glaciers on Indian monsoon precipitation and circulation patterns using land-use land-cover change (LULCC) sensitivity experiments. For performing th...

This study re-examines the relationship between Himalayan snow and Indian monsoon and impact of land surface degradation due to depletion of Himalayan glaciers on Indian monsoon precipitation and circulation patterns using land-use land-cover change (LULCC) sensitivity experiments.
