| 摘 要： | 介绍了一个局地自适应多级模式降水预报系统、以及各级模式对1998年6月9日降水的预报结果，并相互比较。预报结果是：广州区域中心业务模式（75km水平格距）较好地反映了这次降水过程，依托其上的局地各级模式（分别为25km,5km水平格距）能够逐级进一步细致地描述降水过程的空间和时间的分布。这表明自适应多级模式是局地降水预报客观、定量化的有效方法。结果也有利于实际预报人员进一步了解各级模式性能，以便更合理有效地应用数值模拟所提供的信息。

| Abstract: | Using data of wind speed from weather stations and tidal levelsfrom tidal stations near the Pearl River mouth, composite study is carried out of monsoon intensity and sea level variation during 12 El Nino processes in 1955 ～ 1988. The result shows that the winter-mean wind speed is larger than normal by 0.4 m/s in the preceding winter and monthly mean speed is generally higher than normal in the current year of El Nino events, while the monthly mean sea level is lower than normal with negative anomalies of about 6 cm for October and November. Monsoon anomalies in East Asia poses significant influence on sea level anomalies at the mouth. |
