Abstract:
Using the data of Tropical Cyclone Yearbooks from 1951 to 2002,intermonthly characteristics,interannual and interdecadal variation,climate incident,oscillation period about tropical cyclones influencing the northern China are analyzed.The results show that the tropical cyclones influencing the northern China exhibit remarkable intermonthly variations.The dominant period is from July to September,especially the peak period is July and August,but there are no tropical cyclones influencing the northern China during January-April and December.A less increasing trend can be found in the interannual timescale,In addition,the linear trend indicates an increase of 3%/10a.No sharp change can be found with the Mann-Kendall method.In the recent 52 years,the tropical cyclones influencing the northern China show remarkable interannual and interdecadal variability.There is remarkable interannual period of 5 years,and interdecadal oscillation periods with 2-to 4-year,10-to 12-year and 20-to 22-year also can be found.
