摘    要:2003年嘉兴市出现了37天高温天气,并刷新了多项历史纪录,无论从持续时间、强度上都可说是50年一遇。分析发现:2003年的高温天气是7~8月西太平洋副热带高压异常强大,而极涡强度、西风环流指数偏弱所造成的,同时也是天气气候变暖的必然趋势;小波分析结果表明:高温天气主要存在16年和8年周期,2001年起为准两年振荡。

关 键 词:2003年  高温天气分析  嘉兴市  副热带高压异常  西风环流指数  准两年振荡  2001年  历史纪录  持续时间  西太平洋  气候变暖  分析结果  50年  涡强度  年周期

Abstract:With 37 days of high temperature and several new historical records, high temperature weather of Jiaxing in 2003 could be encountered once every 50 years no matter in duration or intensity. It shows that this resulted from remarkably strong west-Pacific Subtropic High in Jul. and Aug. and comparatively weak eddy intensity and west-wind circulation index. It's also a certain result of the climate warming. Outcome of wavelet analysis: high temp. has main periods of respectively 16- and 8- year and there was a quasi-2- year surge since 2001.
Keywords:high temperature subtropical high west wind circulation index  wavelet analysis
