我国长江中下游梅雨锋暴雨研究的进展

我国长江中下游梅雨锋暴雨研究在最近五年中取得了明显的进展，其中有：第一，提出了基于多种实时观测资料的梅雨锋暴雨的多尺度物理模型；第二，建立了梅雨锋暴雨的天气学模型；第三，提出了梅雨锋的详实结构及其维持机理；第四，提出了多种中尺度暴雨的定量卫星遥感反演理论和方法，并形成一系列新的反演产品；第五，成功地研究了双多普勒雷达同步探测和反演中尺度暴雨三维结构的理论和方法；第六，发展了配有三维变分同化系统的中尺度暴雨数值预报模式系统，在2003年淮河抗洪救灾中发挥了积极作用。

Review on Study of Heavy Rainfall within the Meiyu Front in the Middle and Lower Reaches of the Changjiang River

Some progresses on study of heavy rainfall within the Meiyu front in the middle and lower reaches of the Changjiang River for the last five years are made as follow. 1. Muti-scales physical models of heavy rainfall within the Meiyu front based on the real-time observed data are proposed. 2. A synoptic model for heavy rainfall within the Meiyu front is established. 3. The structure of Meiyu front and its maintenance mechanism are discussed. 4. Several kinds of quantitative remote sensing retrieval theories and methods are proposed for meso-scale heavy rainfall; 5. Dual-Dopplor detecting methods and retrieval theories for meso-scale heavy rainfall are successfully studied. 6. The meso-scale heavy rainfall numerical prediction model system with 3Dvar is developed.
