Abstract

Regional water vapor convergence and divergence over the southern margin of the Qinghai-Xizang Plateau (QXP) can be regarded as a good factor for the formation of rainfall climate and extreme weather in the TP and its surroundings. In view of the key region in southern margin of the QXP (the key region for short), summer moisture transport and budget over the key region are analyzed based on the NCEP/NCAR reanalysis data from 1979 to 2010, combined with rainfall station data as well to explore its effects on the rainfall characteristics in the QXP and its surroundings. The main conclusions are summarized as follows. Influenced by the Indian low and the terrain of the QXP, three water vapor transport channels were transformed in the key region from the Bay of Bengal moisture flow, and those led to water vapor divergence over the key region where the southern boundary was the only input one. Meanwhile, different boundaries showed different monthly and interannual variations, especially for the contrary trend of the moisture budget intensity between the western and the eastern boundaries. The budget of input and output boundaries were affected by the activities of the Indian low and the South Asian monsoon, and the output boundaries moisture budget was directly connected with abnormal distribution of rainfall and the development of extreme drought and flood events in the QXP and even the monsoon region surroundings. In addition, the reliability of NCEP/NCAR and JRA-25 reanalysis data in qualitative research over the south margin of the QXP was confirmed by comparison of these tow datasets.
