冬季西太平洋副高异常变化对我国气温的影响及其与前期北太平洋海温的关系

利用1951-2005年全国160个站气温资料、西太平洋副高特征指数和北太平洋海温资料,分析了冬季西太平洋副高强度和位置异常变化对我国气温的影响及其与前期北太平洋海温的关系,结果发现:冬季西太平洋副高强度和西伸脊点与我国气温分别存在着很好的正、负相关关系;前期北太平洋海温距平场呈现厄尔尼诺和拉尼娜分布型及赤道东太平洋海温异常变化,对冬季西太平洋副高强度和位置具有很好的预测指示意义。

Abnormal Variation of Western Pacific Subtropical High in Winter Affecting Atmospheric Temperature in Our Country and the Relation to Northern Pacific Sea Temperature in Prophase

Utilizing atmospheric temperature data of 160 stations in whole country and subtropical high characteristic index in Western Pacific and sea temperature data in Northern Pacific from 1951 to 2005,the paper analyzes the influence on atmospheric temperature in our country of the abnormal variation of intensity and site of the Western Pacific subtropical high in winter,and the relation to Northern Pacific sea temperature in prophase.It finds that the intensity and west-extending ridge dot of the Western Pacific subtropical high in winter is closely connected with the atmospheric temperature in our country.And it indicates a very good denoting signification to intensity and site of the Western Pacific subtropical high in winter as a result of sea temperature departure field in Northern Pacific presenting El Nino and La Nina distributing model and abnormal variation of sea temperature in equator Eastern Pacific.
