西太平洋副热带高压的强度和位置与亚洲地表温度之关系

Relationship between the Ground Surface Temperature in Asia and the Intensity and Location of Subtropical High in the Western Pacific

利用 ＮＣＥＰ／ ＮＣＡＲ再分析资料中的 ５００ ｈＰａ高度场资料和 ＮＣＡＲ地温资料，分析了６～８月西太平洋副热带高压的面积指数、西伸的经度和脊线的纬度等与亚洲地表温度之关系。结果表明，夏季西太平洋副热带高压的强度及位置，与亚洲某些区域的地表温度有明显的关系。关系最密切的是（１００～１１０°Ｅ，３５～４５°Ｎ）附近，位于我国内蒙古西南部、甘肃和宁夏自治区一带以及蒙古人民共和国的南部。另外青藏高原、南亚地区的地表温度与西太平洋副高也有较好的相关。文中对此做了详细分析和讨论。

The NCEP/ NCAR reanalyzed climate data and NCAR ground surface temperature (GST) data are used to analyze the area index, longitude and latitude of the subtropical high in the western Pacific in summer and their relation with the Asia GST. The results show that there is an evident relationship between the intensity and location of subtropical high in the western Pacific and Asia GST. Their correlation coefficients are greater in the region near 35-45°N, 100-110°E, which is in the southwest part of the Inner Mongolia, Gansu and Ningxia Autonomous region and the southern part of Mongolia. In addition, the GST in the Qinghai-Xizhang Plateau and South Asia also has a close relation with subtropical high in the western Pacific.
