The Division and Climatic Characteristics of End-date of Rainy Season in Jiangxi Province
摘要
Abstract
In this paper, using the daily precipitation data of April to July, the pentad precipitation was analyzed to determine the climatologically significance on end-date of the rainy season. Two indi- cators, precipitation and circulation, were used to define the end-date of the rainy season:firstly, u- sing NCEP/NCAR daily reanalysis data in northern hemisphere 500 hPa to determine the date which West Pacific subtropical high ridge line north to skip the 20°N (T20)and 25°N (T25), Secondly, dai- ly rainfall data from April to in July was used to determining the Westerly's system effects of the last heavy rain to rainstorm (or heavy rainstorm) precipitation process end date (TR ). According to T20, T25 and Ta comprehensive judgment, the end of the rainy season dates was identifies. The results showed, there is distinct difference on the end-date of the rainy season during the years in Jiangxi Province, which in the northern is later than southern, and the phase change significantly.关键词
