| Abstract: | Five sets of numerical experiments were performed by using a five-layer limited area primitive equation model Among them,one is for real topagraphy with mean height of 4 000m;and the others are for the heights of 1 000m,2 000m, 3 000m, 3 500m,respectively Their results were compared each other It was shown that: (1) The atmospheric heat source over the Tibetan Plateau and its southeast neighbourhood strengthened with the rising of the Plateau Especially,when the mean height of Plateau was rised from 3 000m to 3 500m,the intensity of the heat source increased significantly and correspondently,the Asian summer monsoon circulations were changed obviously (2) When the mean height of Plateau was rised to 3 500m,the South Asian high in the upper troposphere appears,and the tropical easterly to the south of the high center was strengthened considerably Meanwhile,the low-level thermal low over the Asian continent moved westward to over the Plateau rapidly If the Plateau rised higher than 3 500m,the monsoon meridional cell,with the ascending branch over the Plateau and the two descending branches to the north and south sides of Plateau respectively,was seted up completely As a result of adding of the Plateau monsoon to the monsoon caused by the thermal difference between sea and continent,the Asian summer monsoon was strengthened considerably (3) In response to the rising of Tibetan Plateau,the distribution of rainfall was also changed The positive (increasing) and negative(decreasing) rainfall centers were located in the southeast side of the Plateau and the east coast of the Bay of Bengal,respectively |
