Understanding the atmospheric boundary layer and the effect it has on cloud growth is a fundamental meteorological problem that is important to a broad range of atmospheric questions ranging from venting of pollutants to the free atmosphere to the effect of cloud cover on climate. Observations have clearly shown that clouds can form in distinctive and very organized patterns over expansive areas. The Principal Investigator will continue his research on the organization of mesoscale convection that evolves in time within the planetary boundary layer as cold and dry continental air masses advect over relatively warmer bodies of open water. The Principal Investigator will use observational data collected from a previously held field program along with theoretical studies and numerical models to ascertain important characteristics of the boundary layer over Lake Michigan.

了解大气边界层及其对云增长的影响是一个基本的气象问题，对于从污染物排放到自由大气到云层对气候的影响等一系列大气问题都很重要。观测清楚地表明，云可以在广阔的区域形成独特的、非常有组织的模式。首席研究员将继续他对中尺度对流组织的研究，当寒冷和干燥的大陆气团平流在相对温暖的开放水体上时，中尺度对流在行星边界层内及时演变。首席研究员将使用从先前举行的实地项目收集的观测数据以及理论研究和数值模型来确定密歇根湖边界层的重要特征。
