摘要:
利用日本气象厅历史海温资料与中国160站月降水资料及NCEP再分析资料,分析了近60a东北地区降水以及暖池热含量的变化特征和突变特征,并研究前期10~11月西太平洋暖池关键区(125.5-135.5°E,15.5-20.5°N)0~200m热含量异常与中国东北夏季降水的关系。结果表明,近60a东北夏季降水与前期10~11月暖池关键区0~200m热含量具有明显的年代际变化与突变特征,关键区热含量在90年代中期以后的增暖是一次突变。暖池热含量与东北夏季降水存在密切负相关,暖池发生增暖突变后负相关变好。冷水期与暖水期次年夏季东亚夏季环流呈显著相反特征,冷水期次年夏季东北地区受到有利于降水的环流系统影响,降水偏多;反之降水偏少。
Abstract:
Based on the historical SST from JMA and precipitation data of 160 stations in China and NCEP reanalysis data, nearly 60 a precipitation in northeast of China and the characteristics of warm pool heat content variation and mutation were analyzed, and the relationship between 0~200 m heat content anomaly of key area in the western Pacific warm pool (125.5 135.5 ° E, 15.5 to 20.5 ° N) during the early October to November between the summer precipitation in northeast of China. The results show that:During recent 60 years, there are remarkable interdecadal change and mutation characteristics in summer northeast precipitation and the heat content of warm pool key area with a mutation of key area heat content increasing in the late of mid-90s. There is closely negative correlation between warm pool heat content with the summer precipitation in northeast of China, with better negative correlation after the warm pool heating mutation, the characteristics of east-Asia summer circulation in second summer of the cold-water period and warm-water period are contrary, during the next summer of cold-water period affected by the circulation system conducive to rain, the rainfall is more, whereas less rainfall.
