摘要: 根据1961—2000年辽宁22个代表站夏季高温资料,采用小波分析等统计方法和天气学方法,分析了辽宁夏季高温的年际变化、年代际变化及周期特征。结果表明:辽宁夏季高温出现地域特征明显,年际变化较大,具有12-15 a周期变化。利用NCEP资料得出,夏季高温日数出现异常多、少年的同期500 hPa环流形势具有明显不同。

Abstract: Based on the high temperature data of 22 meteorological stations from 1961 to 2000 in Liaoning province,the inter-annual and inter-decadal as well as cycle changes of summer high temperature were analyzed by wavelet analysis and synoptic method.The result showed that the changes of summer high temperature in Liaoning province took on obvious regional features.The cycle of inter-annual changes was 12-15 a.Based on NCEP data,the circulation situations in 500 hPa were obviously different between anomalous more years and anomalous fewer years of summer high temperatures.
