| 摘 要： | 对GMS红外和可见光两个通道的资料进行了处理，并估计出了700 hPa和850 hPa两个层次的湿度场。将卫星资料估计的湿度场取代数值模式通常的客观分析湿度场进行了对比业务试验。业务运行表明，应用卫星资料后，预报结果有较大改进。

| Abstract: | GMS infrared and visible channel data were processed, and by which 700 hPa and 850 hPa humidity fields were estimated. By using satellite derived humidity field to take the place of conventional humidity field in numerical model, the control tests were made. The operational tests show that the forecast results were greatly improved. |
