中国大气逆辐射的气候计算及其分布特征

CLIMATOLOGICAL CALCULATION OF DOWNWARD ATMOSPHERIC RADIATION FOR CHINA AND ITS CHARACTERISTIC DISTRIBUTION

本文根据1979年5—8月季风试验(MONEX)期间印度8个辐射探空站资料,以及同期青藏高原气象科学实验和1982年8月至1983年7月青藏高原辐射观测资料,详细地讨论并提出了大气逆辐射的气候计算式。该式具有物理意义清晰、拟合精度较高及普适性较好的优点。首次计算了全国218站的大气逆辐射,并就其在全国的地理分布及其随纬度、拔海高度季节变化进行了分析,得到一些有意义的结果。

By using the data from 8 Indian radiation-sounding stations during theMONEX of May-August 1979 and the radiation measurements during the QXPMEX(the Qinghai-Xizang Plateau Meteorological Science Experiment)conducted during thesaid time and from August 1982 to July 1983, a useful expression for downward atmo-spheric radiation is presented through detailed discoussions. The expression is marked bydistinct physical implications, higher fitting accuracy and considerable universality. Theregime of the downward atmospheric radiation is calculated for the first time for 218 sta-tions in the meteorological network of China and investigation done of its geographic dis-tribution and variation with latitudes, elevations and seasons, thus bringing about someinteresting results.
