Study of Lake and Land Breezes Over Small Lakes

9319455个阿里特小湖泊是常见的地理特征。湖泊的大气效应对水资源、大气污染扩散和改善当地小气候等许多实际问题具有重要意义。也有证据表明，小湖泊可以对白天对流云的发展产生重大影响。在一些情况下，湖风诱导的辐合提供了深对流的触发，而在另一些情况下，观察到了小湖泊抑制对流云。这些影响对更大范围的天气环境有反馈作用。这项研究的目的是对小湖泊的大气影响有一个全面的物理理解。具体而言，首席调查员将研究小湖泊对大气影响的大小、这种影响的时间和空间范围，以及产生测量到的影响的基本物理过程。首席调查员将结合分析尺度、数值模拟和一项小规模、重点明确的观测研究来实现他们的目标。***

9319455 Arritt Small lakes are commonplace geographical features. The atmospheric effects of lakes are important to many practical problems such as water resources, air pollution dispersion and modification of the local microclimate. There is also evidence that small lakes can substantially affect the development of daytime convective clouds. In some cased the lake breeze induced convergence provides a trigger for deep convection while in other cases small lakes have been observed to suppress convective cloudiness. Such effects have implications for feedbacks to the larger scale weather environment. The objective of this research is to develop a comprehensive physical understanding of the atmospheric effects of small lakes. Specifically, the Principal Investigators will study the magnitude of the small lake effects on the atmosphere, the temporal and spatial extent of such effects, and the fundamental physical processes that produce the measured effects. The Principal Investigators will use a combination of analytical scaling, numerical simulations and a small, well-focussed observational study to accomplish their objective. ***
