摘要

摘要: 以江苏夏季最高气温和冬季最低气温场为例,研究海气耦合作用对区域气温场异常型态的影响。结果表明,江苏夏季最高气温受到同期海气耦合作用的影响较明显,冬季最低气温受同期海气耦合作用的影响较少;从一定意义上说,夏季最高气温的降低是由于东太平洋遥相关型强度的变化及同期北太平洋海温距平分布型的强度加强所致,而冬季最低气温的升高则是由于WA型及欧亚大陆上空环流型强度的变化及同期北太平洋海温距平分布型的强度减弱所致。

Abstract: We made a study on relationship between summer maximum and winter minimum temperature of Jiangsu, SST and 500 hPa field in order to understand how air-ocean interaction influences on regional climatic anomalous pattern. Summer air-ocean interaction makes a strong impact on summer maximum temperature in Jiangsu. Winter air-ocean interaction has a little influence on winter minimum temperature. The strengthening of eastern Pacific pattern (EP) and the change of distribution of summer northern Pacific SST anomaly account for the drop of summer maximum temperature. The weakening of the distribution of summer northern Pacific SST anomaly and the variation of WA pattern and Eurasia circulation account for the rise of winter minimum temperature.
