In this paper

Geostationary Meteorological Satellite （GMS） infrared blackbody temperature （Tbb） data from June to August 1998 are used to automatically track the activity of Mesoscale Convective Systems （MCS） over the Tibetan Plateau. Consequently

the features of MCS

such as area

intensity

life cycle

activity region and shape

are obtained. High Resolution Limited Area Analysis and Forecasting System （HLAFS） values provided by China National Satellite Meteorological Center are used to study the relationships between the MCS movement routes and their environmental physical field values

based on the distribution and movement routes of MCS over the Tibetan Plateau. Favorable environmental physical field charts of influencing MCS movement ouf of the Tibetan Plateau in different UTC are developed using spatial data mining techniques at levels of 400hPa and 500 hPa

respectively.
