梅雨期3类不同形成机制的暴雨被引量：26
《气象学报》2012年第3期452-466,共15页刘建勇 谈哲敏 张熠 
国家公益性行业(气象)专项(GYHY201006004);高校博士点专项科研基金(20080284019);国家自然科学基金项目(40805019、40605017)
通过对1998—2007年观测资料的分析,根据影响梅雨期暴雨发生、发展机制的不同,将梅雨期暴雨分为外强迫型、自组织型和非组织化局地型3种类型。外强迫型主要包括冷槽推进型、西南涡移出型和北槽南涡型,该类型暴雨主要是由大尺度环流的动...

Mesoscale Predictability of Mei-yu Heavy Rainfall被引量：10
《Advances in Atmospheric Sciences》2009年第3期438-450,共13页刘建勇 谈哲敏 
supported by the National Key Scientific and Technological Project 2006BAC02B03,2004CB418300;under the FANEDD 200325;The Specialized Research Fund for the Doctoral Program of Higher Education (20080284019);National Natural Science Foundation of China under Grant No.40325014
Recently reported results indicate that small amplitude and small scale initial errors grow rapidly and subsequently contaminate short-term deterministic mesoscale forecasts. This rapid error growth is dependent on no...
