Abstract:The itnerannual variation of the landfalling locations of the western North Pacific typhoons and tropical cyclones (TCs) in China from July to September and its association with the summer East Asia/Pacific pattern (i.e.,EAP pattern) teleconnection of the atmospheric circulation anomalies over the Northern Hemisphere are analyzed by using the data of wind and geopotential height fields from JRA-25 analysis of Japan Meteorological Agency during 1979-2007 and the observational data of tropical cyclones from the US Joint Typhoon Warning Center (JTWC). Especially the correlation between interannual variation of the numbers of landfalling typhoons and TCs to the north of Xiamen and the summer (June-August) EAP index is analyzed. The results show that in summer (June-August) with a high EAP index, the wave-train distribution of “-, +, -” EAP pattern teleconnection of geopotential high anomalies will appear over East Asian and the western North Pacific, and the position of the western Pacific subtropical high will shift northward and eastward at 500 hPa from July to September. In this case, most of the moving tracks of typhoons and TCs over the western North Pacific will be more northward, which can cause more landfalling typhoons and TCs to the north of Xiamen. On the contrary, in summer (June-August) with a low EAP index, the wave-train distribution of “+, -, +” EAP pattern teleconnection of geopotential height anomalies at 500 hPa will appear over East Asia and the western North Pacific, and the position of the western Pacific subtropical high will shift southward and eastward from July to September. In this case, most of the moving tracks of typhoons and TCs over the western North Pacific will be more southward. Therefore, this will cause less landfalling typhoons and TCs on the coast of Southeast China to the north of Xiamen from July to September, and more typhoons and TCs will make landfall on the coast of South China to the south of Xiamen.
