Observed Impact of the South Asian Summer Monsoon on the Local Meteorology in the Himalayas
Abstract
The South Asian summer monsoon (SASM) is the most important climate system in Asia. Using observational data from the HEST2006 campaign (Himalayan Exchange between the Surface and Troposphere 2006) and large-scale grid data, this paper analyzed the SASM impact on local meteorological parameters, including radiation, temperature, humidity and wind, in the Himalayas. The SASM experienced one active and one break period during the HEST2006 campaign. The local meteorological parameters in the Himalayas exhibit a great difference in the behaviors corresponding to the periods in which the SASM is active or break. The radiation fluxes are greater in the break period than those in the active period. The air temperature and specific humidity are lower, but the soil temperature and wind speed are higher in the break period versus the active period. Further analysis indicates a potential impact of the SASM on the meteorological features of the Himalayan region.
