In order to improve the level and efficiency, based on a variety of observation data in Xuzhou from 2010 to 2012, by means of a new effectiveness evaluation method for rainfall enhancement operations, considering the topographic features and working habits of Xuzhou, the rainfall enhancement potential analysis models for 12 hour forecast and nowcasting are established. The potential areas are classified into two categories: ClassⅠ(smaller) and class Ⅱ (larger), and rainfall enhancement operation advices are provided by the two categories. Results of rainfall operations in Xuzhou in 2013 show that the rainfall enhancement potential analysis models for 12 hour forecasting and nowcasting have a satisfactory accuracy. Based on the models, the operation procedures of rainfall enhancement Xuzhou are revised to improve the efficiency of the command staff and the effectiveness of rainfall enhancement operations.
