Mesoscale Influences on the Initiation and Development of Clouds and Precipitation

对局部降雨事件的时间和地点的预报的改进取决于对对流风暴的形成和组织过程的更好理解。中尺度大气边界辐合和地形效应是对流云形成和发展以及决定降水中尺度分布的主要机制。利用数值模拟和以前现场实验的数据，首席研究员将研究导致对流风暴发展的物理过程的贡献、相互作用和敏感性。重点将放在中尺度大气边界和地形效应的作用上。//

Improved forecasts of the timing and location of localized rainfall events are dependent on improved understanding of the processes responsible for the initiation and organization of convective storms. Convergence along mesoscale atmospheric boundaries and topographic effects are primary mechanisms for convective cloud initiation and development and in determining the mesoscale distribution of precipitation. Using numerical simulations and data from previous field experiments, the Principal Investigator will examine the contributions, interactions and sensitivities of the physical processes leading to convective storm development. Emphasis will be placed on the role of mesoscale atmospheric boundaries and topographical effects. //
