Abstract:The spatial distribution of tropical cyclone precipitation shows that the heavy torrential rain caused by the landing northward tropcial cyclone occurs concentrately over the northwest of North China flatlands and the southeast of the Shandong-Liaodong penninsula. The comparative analysis was made and the result shows that the formation of the two heavy torrential rain areas aparted so far away were mainly realated to the position of the subtropical high in the preceding stage,the track of the landing northward tropical cyclone and the distribution of the physics fields except for the orography effect. At last,the indices and methods for forecasting these two types of heavy torrential rain were given correspondingly.
