Analysis of Relationship between Characteristics of Typhoon Affecting the Taihu Basin and the early Sea-Surface Temperature

Abstract:

A standard was proposed to define the typhoon affecting the Taihu Basin (TATB) based on the typhoon source, landing location, moving path, typhoon-affected area and precipitation in the Taihu Basin. According to the definition, 230 typhoons were extracted from the 62 years observation data (1949-2010) to analyze the relationships between the characteristics of typhoon which affacted the Taihu Basin and the early relevant regional sea-surface temperature. The results showed the tendencies of the TATB frequency and the earliest affected time were no significant change throughout the long series of statistics; the latest affected time was postponed obviously throughout the long series of statistics; the change of typhoon frequency had two notable periods (21 years and 7 years), and the 21years period was relatively stable throughout the long series of statistics; when the spring of the sea-surface temperature (SST) of the west Pacific Ocean raised and the SST of the east Pacific Ocean near the equator decreased, easy to cause the frequency of the TATB might increase and vice versa TATB frequency decrease. The research results have a certain significance on the Taihu Basin flood control.
