摘要:

利用NCEP逐日再分析资料、OLR资料和SST资料对2006年夏季重庆地区持续高温干旱过程的天气特征、环流背景及形成机理进行了初步分析,结果表明:造成重庆持续异常高温伏旱的主要原因是西太平洋副热带高压的异常,而它与南亚高压位置和强度的异常、极涡和副热带急流的变化、西太平洋暖池偏暖等因子都有较大关系。

关键词: 重庆, 高温伏旱, 天气特征, 环流背景, 形成机理

Abstract:

The weather characteristics, circulation background and the formation mechanism of the abnormal lasting high temperatureand drought event occurred in Chongqing in summer of 2006 are analyzed by using reanalysis data of NCEP, OLR and SST data. Re2sults show that the abnormity ofWest Pacific Subtrop ical High resulted in this lasting high temperature and drought event, and this ab2normity ofWest Pacific Subtrop ical High was greatly affected by such factors as the abnormal position and strength of Southern AsiaHigh, changes of Polar vortex and subtrop ical jet stream, warmingWest PacificWarm Pool and so on.

Key words: Chongqing, summer high temperature and drought, weather characteristics, circulation background, formation mechanism
