9702715 Bradley The Faculty Early Career Development (CAREER) award focuses on research and enhanced educational opportunities in extreme rainfall estimation for flood hazard assessment. Estimation of the upper limits of storm rainfall for design of high hazard structures is based on the probable maximum precipitation (PMP). Many of the concepts in PMP estimation were developed in the 1930's and 40's. In recent years there have been substantive advances in the observation, understanding, and modeling of convective weather systems. Research will be carried out to improve PMP estimation using modern meteorological methods. The principal objectives of the research plan are to: (1) develop unique climatological information on extreme rainstorms in the central United States, to improve our understanding of the hydrometeorological controls on extreme rainfall, (2) examine fundamental concepts of the PMP approach, including moisture maximization, using mesoscale numerical modeling, (3) develop and evaluate a probable maximum precipitation procedure for major river drainages in the central United States based on descriptions of the large-scale circulation anomalies associated with extended periods of excessive rainfall. The objectives of the educational plan are to: (1) integrate the use of remote sensing information from modern weather observing equipment into graduate and undergraduate courses, (2) develop Internet-based instructional material to support education in remote sensing technologies and hydrometeorological data analysis. ***

9702715布拉德利教师早期职业发展（职业生涯）奖侧重于研究和增强极端降雨估计洪水灾害评估的教育机会。 高危险性建筑物设计中的暴雨降雨量上限是根据可能最大降雨量（PMP）估算的。 PMP估计中的许多概念是在20世纪30年代和40年代发展起来的。 近年来，在对流天气系统的观测、理解和模拟方面取得了实质性的进展。 将开展研究，利用现代气象方法改进PMP估算。 研究计划的主要目标是：（1）开发美国中部极端暴雨的独特气候信息，以提高我们对极端降雨水文气象控制的理解，（2）使用中尺度数值模拟检查PMP方法的基本概念，包括湿度最大化，（3）根据对与长时间过量降雨相关的大尺度环流异常的描述，制定并评估美国中部主要河流流域可能的最大降水程序。 该教育计划的目标是：（1）将现代天气观测设备提供的遥感信息的使用纳入研究生和本科生课程，（2）开发基于互联网的教学材料，以支持遥感技术和水文气象数据分析方面的教育。 ***
