Elevation Dependency of Precipitation over Southern Slope of Central Himalaya

Precipitation plays vital roles in the global water cycle, knowledge of spatial and temporal variation precipitation is essential to understanding extreme environmental phenomena such as floods, landslides, drought. In this paper, integrated characteristics during 1980–2016 over Nepal along with seasonal elevation dependency were examined for three different regions country using Multi-Source Weighted-Ensemble (MSWEP) product. The distribution mean annual varies significantly highest (lowest) ~5500 (~100) mm/year Arun valley (Manang Mustang). regime determined by contribution monthly amount distinct gradients between eastern western sides pre-monsoon, post-monsoon, winter seasons. On contrary, monsoon tends more heterogeneous visible differences lowland, midland, highlands similar one. Further, revealed that post-monsoon central are very similar, whereas was found slightly higher than season region. areas region located 2000-2500 m, which 500 1000 m country. Overall, summer increases gradually upto 2500 then decreases increasing elevation, almost identical each interval m.
