ANALYSIS ON THE CHARACTER OF TROPICAL CYCLONES MAKING LANDFALL ON DIFFERENT REGIONS OF CHINESE CONTINENT
摘要
Abstract
By using ArcGis and FORTRAN routine, we get detailed information about the location (longitude and latitude) of the tropical cyclones (TCs) making landfall on the Chinese continent from 1949 to 2008. The southeast coastline (110～122 °E) with more landfall TCs was selected as the study region and divided into 12 subsections with 1 ° intervals of longitude. The duration from July to September in each of the years was the study period. The result showed that the average sustaining time before and after TC made landfall on the subsections east of 118°E was longer than those west of it. Before landfall, the average TC intensity of the subsections east of 118°E was stronger than that west of it; but after landfall, the difference between the west and east was not obvious. The index of destructive potential for the period before/after landfall was defined as TDP1/TDP2. The maximum of TDP1/TDP2 occurred in the subsection of 119, 120 °E/110, 111 °E. The impact of ENSO event on the landfall TC frequency and average location of the whole region at 110～122 °E was not obvious, but it was different for the subsections. The average TDP1 of the subsections in an ENSO event varied, but it is larger in warm events than in cold events for TDP2. The rainstorm days of each station caused by TCs from different subsections were counted respectively. The results suggested that the rainstorm days of the subsections east of 118 °E were much more than that west of it. Larger values were mainly distributed in the subsections of 119, 120 °E and 110, 111 °E.关键词
