Abstract: Due to the special landform and the problem on obstacles of radar data in Plateau and mountainous regions,it is very difficult to utilize the localization of SWAN system establishing the severe convective weather of short-time forecasting and nowcasting system. By taking Tibet plateau area as an example,based on the characteristic of MICAPS and SWAN system platform,considering the habit of employees to use the system in computer analysis and forecast of current meteorological stations,Utiliz the database about the satellite remote sensing data,automatic meteorological station data,lightning location data and routine meteorological elements of observation data,and the models about synoptic model,dynamic-statistical diagnosis index and empirical forecast model in the region of Tibet.It has design of the practical system which can realize the integration of information analysis function of MICAPS and SWAN system on the VB language environment and being suitable for the Tibet of short-time forecasting and nowcast warning.Ideas of system integration on this system will provide a beneficial exploration ideas and implementation techniques for the regionalization and localization of meteorological warning and forecast system in different areas.Also,it has important practical guiding significance.
