Cyclogenesis and Frontogenesis Processes Over Western North America and Vicinity

博萨特博士是大气科学领域的领先概念学家之一。他将继续并扩大他以前关于中纬度气旋发生和锋生的工作，依靠气候学和个案研究调查，其中包括行星、天气和中尺度上的大气过程。博萨特博士将致力于三个主要研究项目。第一个是对美国西部山间地区的气旋和锋面形成的调查。当高层对流层扰动遇到山区障碍时，就会出现特别困难的预报情况。有时，随后的流型会在山区形成准静止的风暴系统。在其他时间，扰动将继续向东移动。通过他的分析，博萨特博士想要区分导致这两种截然不同的天气模式的条件。第二个主要研究领域是研究大气中不同层次上影响风暴发展的波动扰动的合并和分离。最后，博萨特博士将开展一项新的研究项目，研究中纬度气旋发展与副热带急流产生的瞬变扰动之间的相互作用。除了他们内在的科学兴趣，博萨特博士希望回答的问题对改进天气预报业务也有直接影响。

Dr. Bosart is one of the leading synopticians in the field of atmospheric sciences. He will continue and expand upon his previous work on midlatitude cyclogenesis and frontogenesis, relying on climatological and case study investigations which encompass atmospheric processes on the planetary, synoptic and meso-scales. Dr. Bosart will pursue three major research thrusts. The first is an investigation of the cyclone and frontal formation in the intermountain regions of the western United States. A particularly difficult forecast situation arises when upper tropospheric disturbances encounter mountain barriers. Sometimes the subsequent flow pattern results in the development of a quasi- stationary storm system in the mountain regions. At other times, the disturbance will continue moving eastward. Through his analyses, Dr. Bosart would like to distinguish between the conditions which cause these two very different weather patterns. The second major area of research is the study of merger and separation of wave disturbances at different levels in the atmosphere affect storm development. Finally, Dr. Bosart will take on a new research project, looking at the interaction between the midlatitude cyclone development and transient disturbances emanating from the subtropical jet stream. In addition to their intrinsic scientific interest, the questions Dr. Bosart hopes to answer have direct implications for improved operational weather forecasting.
