synoptic system

On analysis six high-temperature weather processes on synoptic situation, element field and NWP, some characteristics of effect system and some forecasting information have been got.

从形势场、要素场和数值预报产品等方面，对2002年河南省6次区域性高温天气过程进行对比分析，找出了影响系统的若干特征及河南高温天气过程预报信息。

Tropical cyclone, frontal cyclone, cold high and southwest monsoon are the main synoptic systems affecting China Sea. When one of them controls the sea, the wave field on the sea has its own features due to the special wind field of this system.

影响中国近海的主要天气系统有热带气旋、锋面气旋、冷高压和西南季风，它们的风场结构很不相同，由此引起的海浪场也各具特点。
