青藏高原西部冬季地表净辐射与中国降水的关系

本文利用1982年8月－1983年7月在青藏高原地区进行的辐射平衡观测资料，计算了高原西部地区历年冬季（11－2月）的地表净辐射。通过对高原西部冬季地表净辐射的分析阐明了高原西部地表加热场的特征，并讨论了它与我国的西南秋雨、长江流域伏旱以及黄河上游雨季降水等的关系。

RELATIONSHIP BETWEEN THE SURFACE NET RADIATION IN THE WESTERN QINGHAI-XIZANG PLATEAU AND THE PRECIPITATION IN CHINA

In this paper were estimated the surface net radiations over western Qinghai-Xizang Plateau in winter (from Nov. to Feb.)of 1961 ~ 1981 using the observed data of surface radiation balance over the Qinghai-Xizang Plateau in the period from August 1982 to July 1983. Base on the analyse for the surface net radiation during the winter of the year , the paper expounds the characteristics of surface heating fields in the western Plateau and discusses the relationship between the wintertime surface net radiation over the Western Plateau and precipitation in the Southwestern China in Autumn, Mid-Summer drought along the Yangtze River basin as well as the precipitation in the upper reaches of the Yellow River during the rainy season.
