专家简介：
傅刚，中国海洋大学海洋与大气学院海洋气象学系教授，博士研究生导师。长期从事海洋气象研究工作。在国际上较早地系统开展黄、渤海海雾研究，揭示了海温、辐射等对海雾影响的机制，建立了海雾数值预报系统，出版英文专著《Understanding of Sea Fog over the China Seas》。系统开展海上爆发性气旋研究，建立北太平洋和北大西洋爆发性气旋数据库，提出了高低空位涡相互作用促使气旋迅速发展的新观点。著有《海洋气象学》。
报告摘要：
Explosive Cyclones (ECs), also called “meteorological bombs”, are referred to as a kind of pressure-rapidly-dropping cyclones which often occur over the mid- or high-latitude oceans and accompany with severe weathers such as strong winds, heavy rainfalls/snows, flood and so on. In this talk, the climatological features of ECs over two basins in the Northern Hemisphere are first documented. The concepts of “PV streamer”, “PV hook” and “treble-clef” are then introduced. The dynamic and thermodynamic processes characterized by “PV streamer”, “PV hook” and “treble-clef”, as well as the evolution and connection of these three shapes of PV are examined.
