Abstract: The Tibetan Plateau weather system produce an important effect on the precipitation of Tibetan Plateau and its downstream region.The Plateau low vortex is active on the plateau as one important weather system.Applications of TRMM satellite provide a new way to research the Tibetan Plateau weather system.Some research on Plateau low vortex and applications of TRMM satellite has been reviewed in this paper.It includes the Plateau low vortex's qualitative understanding, structure and the interaction of Leeward shallow weather systems, the basic data of TRMM satellite, and its applications both in and out of Plateau region.
