中国地—气系统长波射出辐射（OLR）的气候特征

根据ERBE和ISCCP资料讨论了云对地—气系统长波射出辐射（OLR）的强迫作用及纬度、大气温度等因子的影响。分析了OLR场与500hPa及地表有效辐射场的相似问题。阐述了OLR在全国的分布特征，指出冬季OLR场大致呈纬向型．夏季为一不对称的鞍形场。年分布与1月的相似。最后还就各区域的OLR年变化特征进行了讨论．

CLIMATOLOGICAL CHARACTERISTICS OF EARTHATMOSPHERE SYSTEM OLR OVER CHINA

Using ERBE and ISCCP data investigated are the forcing of cloud cover on the earth - atmosphere system outgoing longwave radiation (OLR), and effects of latitude and atmospheric temperature upon OLR,with analysis done of the similarity of the patterns of OLR to effective radiation at 500 hPa and surface. Study is also made of the OLR distribution features over the country, indicating that the winter (summer) OLR has a roughly zonal (asymmetric saddle) pattern and its annual distribution is similar to the Januarys. Finally,the yearly variation is discussed for each of the subregions
