摘要
本文用1961～1985年共25年青藏高原60个站的地气温差资料,用季国良的回归方程计算了高原地面加热场强度,并且分析了它的气候特征。结果发现高原地面加热场强度比叶笃正(1979)的计算值小29%,根据自然正交函数分析和载荷量计算,发现玉树和日喀则两站地面加热场强度的平均距平可以粗略地代表整个高原。高原地面加热场具有显著的3年、准5年和准11年周期,在冬季和春季地面加热场的持续性很强。
Using the 25 years (1961-1986) data set of 60 observation stations over the Qinghai-Xizang Plateau , the intensity of the Plateau surface heating fields is calculated according to regression eguations of Ji(1986) and their climatic characteristics are analysed. It is found that their values are only 71 percent of that given by Ye(1979) and the average departures of surface heating eguations of 2 station (Yushu and Rikaze) can represent roughly that of the whole of the Plateau by Empircal Orthogonal Function Analyses and calculations of load values. They have remarkable quasi-3 years, 5 years and 11 years periods and persistences in winter and spring.
