摘要
简述了东北冷涡的形势特征、气候特征、天气特征与强对流特征;回顾、综述了东北冷涡形成、发展、维持、消退期的研究成果,特别是东北冷涡强对流特征的研究进展;讨论了东北冷涡强降水、强天气等预报业务的难点及其研究方面存在的问题。认为:需要依靠现代雷达、卫星等观测设备和数值模拟手段,加强东北冷涡暴雨及强天气机制研究,提高东北冷涡天气的预报水平。
The circulation characteristic,climate characteristic,weather characteristic and severe convection characteristic of cold vortex over Northeast China(NECV)are briefly described and the results of forming phase,developing phase,maintaining phase and weakening phase of NECV are reviewed and summarized,especially the research on severe convection characteristics.The puzzle in operational weather forecast such as heavy rain,severe weather is also discussed.It is necessary to do further research of the mechanism...
