Abstract: Based on the analysis of the hail weather process occurred in Tongliao region of Inner Mongolia from the establishment of the new weather radar station to the year of 2013, a total of 9 forecast indexes for hail weather were found. In order to apply the obtained forecast indexes to the practical work of short-term forecast and nowcasting, the performance of the indexes was analyzed, and the indexes were combined by objective forecasting method. The index weighted integrated method was used in this study. In this method, the indicators were endowed with different weights according to their relative significance and were then integrated with weights. The forecast model equations were subsequently established and a binding parameter of the indicators was obtained which was used as a judgment basis for the occurrence of hail. The established forecast model may be helpful for improving the forecasting and warning capability for the hail weather in Tongliao region.
