青藏高原地区大气辐射加热场的季节变化

THE SEASONAL VARIATION OF ATMOSPHERIC RADIATIVE HEATING FIELDS OVER THE QINGHAI-XIZANG PLATEAU

本文利用美国犹他大学气象系新近发展的辐射和云参数化模式对青藏高原地区甘孜、那曲、拉萨三站及东部平原地区的南京1982年8月—1983年7月的辐射通量和大气加热率进行了计算,分析研究了高原地区大气辐射加热场的季节变化特征及其与气候的关系,并对一些主要的影响因子进行了简要的讨论。

In this paper, a radiation and cloud parameterized model newly developed in the Department of Meteorology, University of Utah, U.S.A. has been used to compute the atmospheric radiation fluxes and heating rate from August 1982 to July 1983 at Garze, Nagqu, Lhasa over the Qinghai-Xizang Plateau and Nanjing in the eastern plain. Analyses of the seasonal variation characteristics of atmospheric radiative heating fields over the Plateau and relations with weather and climate, and simple discussion of a few main factors affecting atmospheric radiative properties, are also presented.
