| 摘 要： | 将极轨卫星HIRS/2探测仪的高分辨率亮温资料，经过定标、定位和其它一些预处理后，不经过反演，直接和其它观测资料一起用最优内插(OI)方法进行分析，给出数值预报初始场，并用国家气象中心的准业务有限区预报模式做预报试验。对比试验结果表明，在数值预报中直接使用亮温比使用反演资料更好。

| Abstract: | A new method to utilize HIRS/2 (High Resolution Infrared Radiation Sounder Model 2) data in NWP (Numerical Weather Prediction) is given. After the geographical location, calibration and other preprocessing, HIRS/2 brightness temperatures (Tb) data from the polar orbiting satellite and conventional meteorological data are directly applied for building an initial field of NWP by using the optimum interpolation method without any retrieval procedures. Analysis and forecast experiments are carried out based on the limited area model from National meteorological Center of China. The preliminary results show that the forecasts from direct Tb data are better than those from satellite retrieval data. |
