Abstract: The evidences have indicated that rainstorms are usually related with the movement of MCSs, however, the factors of influencing MCSs movement are very complex. In this paper, GMS infrared blackbody temperature over the Tibetan Plateau from June to August 1998 are used to automatically track the
movement routes of MCSs. Based on these, spatial data mining method, decision tree, is used to develop the relationships between the movement routes of MCSs and their environmental physical field values, the results indicate that it is feasible to forecast the movement routes of MCSs using decision tree.

Key words: mesoscale convective systems, decision tree, Tibetan Plateau, mesoscale convective systems, decision tree
