摘要Based on a series of topographical and thermal sensitivity experiments, the physical processes on the changes of Asian summer monsoon caused by the Himalaya elevated heating were investigated. Six different Himalaya–Iranian Plateau mountain heights were used: 0, 20, 40, 60, 80, and 100 % in the first group (called HIM). The no sensible heating experiments (called HIM_NS) were also performed with the same six mountain heights, but the surface sensible heating was not allowed to heat the atmosphere. The results indicate that the elevated heating effect of the Himalaya gradually intensified when the Himalaya uplifts. The establishment of SASM over the South Asian land which is characterized by the strong precipitation over south slope of the Tibetan Plateau and the huge warm anticyclone in the upper troposphere are in proportion to the elevated heating effect of the Himalaya. Further analysis suggests that the surface heat fluxes over the Himalaya keep almost unchanged during the uplifting, but the lifted condensation level reduces gradually over the regions where the mountain uplifts. The condensation moisturing increases correspondingly and leads to the increase of latent heating in the upper troposphere. Therefore, the positive feedback between the moist convection over the south slope of the Himalaya and monsoon circulation over Indian subcontinent forms and the successive precipitation over the South Asian land is maintained.
