根据两种不同的方法(即直接法和斜率法),对中国大陆地区有关云的异常吸收问题进行了初步的探讨,研究表明:我国大陆地区云辐射强迫比小于1.2;云对短波辐射的吸收西部要比东部小,但季节变化较东部略大;在青藏高原地区,文中得到的云辐射强迫比约为1.13。
Cloud absorption anomaly is analyzed by two methods: direct and slope methods. The results indicate that cloud radiative forcing ratio R is generally smaller than 1.2. Moreover, the absorption is smaller in the western China than that in the eastern China, but the latter's seasonal variation is relatively greater. Over the Tibetan Plateau, R is roughly equal to 1.13. However, As there are greater errors of retrievals in its east regions, we have to do further investigations on this problem.
