radiosonde data

In this study, the exact values of dry and wet path delay are calculable by using the radiosonde data in four selective stations ( Yap, Guam, Guangzhou, and Shanghai).

Then, cloud drift winds of geostationary meteorological satellites-GMS 5 have been added in the GRAPES three-dimensional variational data assimilation system with radiosonde data. The impact of water vapor winds and infrared cloud drift winds in NWP have been checked by comparing and analyzing the result of assimilation.

然后，把云迹风资料放到GRAPES三维变分同化系统中进行同化，通过将不同观测类型资料的同化结果进行对比，探讨了红外通道和水汽通道云迹风资料对数值预报分析场的影响；
