摘要
本文依据1987年9—11月西太平洋热带海域海洋大气综合考察中双波长微波辐射计观测系统和红外窗区辐射计所得到的观测资料,分析研究了考察海域的水汽和云的变化特性,得到了一些有意义的结果。双波长微波辐射计观测系统可以获得水汽场的动态变化和云中液态水的演变;西太平洋海域的个例显示出辐合区的垂直气柱水汽含量比非辐合区的明显大的特征;用红外亮度温度可以近似估计晴空大气垂直气柱水汽含量。
The evolution of water vapor and clouds over the western Pacific Ocean (5°N - 5°S, 125 - 150°E) have been studied with observations obtained by a shipborne dual-wavelength microwave radiometer system and an infrared radiometer working in the IR window region during Sept. - Nov. 1987, the third survey over this area. Some useful results are presented in this paper. The dual-wavelength microwave radiometer is feasibly measuring means over ocean as well as over land. It can be used to obtain the evolution of water vapor and liquid water contents in clouds. Some cases show that the precipitable water in the convergence region is apparently greater than that in divergence region, the atmospheric precipitable water in the clear atmosphere can be determined approximately by infrared brightness temperature.
