9303825 Smith It is known that orography exerts an important influence on atmospheric motions. It is considered to be crucial that the effects of mountains be properly included in numerical prediction models whether they focus on climate, synoptic, regional or local weather. In previous research on this topic, the Principal Investigator has been instrumental in advancing fundamental knowledge of atmospheric flows around mountains and the influence of these flows on the atmosphere. The Principal Investigator will attempt to determine the nature of the transition between three-dimensional laminar mountain wave flows and mountain flows with dissipation and wakes. Using numerical models and observational studies, the Principal Investigator will further refine the conditions under which different atmospheric flows occur near mountains. ***

9303825史密斯众所周知，地形对大气运动有重要影响。人们认为，无论是侧重于气候、天气、区域还是当地天气，在数值预报模型中适当地包括山脉的影响都是至关重要的。在以前关于这一专题的研究中，首席调查员在促进关于山脉周围的大气流动以及这些流动对大气的影响的基本知识方面发挥了重要作用。首席调查员将试图确定三维层流山波流和具有耗散和尾迹的山流之间的过渡的性质。利用数值模型和观测研究，首席调查员将进一步完善在山区附近发生不同大气流动的条件。***
