Short Range Heavy Rain Numerical Prediction in the Institute of Atmospheric Physics, Chinese Academy of Sciences during Rainy Season of 1998
1998年中国科学院大气物理研究所气候与环境预测研究中心汛期暴雨短期数值预测

The very severe flooding occurred in the Changjinag River during rainy season of 1998. In this paper, heavy rainfall processes are analyzed from June to August and the results of the real time heavy rain numerical predictions by IAP ETA Model are introduced. NCEP data is used as initial fields for input of the ETA model since 1998 and predictional results are showed publicly through Internet. The predictional products showed that ETA coordinate limited area numerical model is one of very useful tools for the prediction of heavy rainfall during rainy season of 1998. And, NCEP data is also very helpful to prediction, especially in the data-sparse areas of Tibetan Plateau and vast ocean.
