中国地表热源的气候学特征

利用研制的地表热量平衡各分量的气候计算方法，结合全国６个热平衡站资料，计算并讨论了地表热源在全国的分布特征，分析了地面对大气加热的特点以及地表热源的参数化问题。指出季风气候背景、纬度、地形和地表湿润状况是决定地表热源特征的重要因素。就全年来说，在我国湿润、半湿润地区，潜热是地面加热大气的主要形式，西北干燥区则以感热加热为主。

CLIMATOLOGICAL CHARACTERISTICS OF GROUND HEAT SOURCES OVER CHINA

Using the developed climatological calculation scheme for components of ground heatbalance and in the context of data from six heat-balance stations of China,investigation is per-formed of the heat source distribution features on a national basis along with analysis of the waysthe ground heats the atmosphere and the parameterization of the sources. Evidence suggests thatthe monscon-climate background, latitude,terrain and ground humidity are the major factors de-termining the surface heat source features On an annual basis, ground latent heating representsthe main form in the moist and semi-moist regions and the sensible heating is dominant in thearid area of Nw China.
