Numerical, Diagnostic, and Climatological Studies of the Dynamics and Prediction of Mesoscale Weather Systems

将确定的四个具体目标是：(1)融化和云下层蒸发在形成低对流层倒槽中的作用；(2)地面通量、融化和低对流层蒸发对含涡中尺度对流系统的结构、环流和放大的影响，(3)中尺度对流复合体(MCC)多发区域的大尺度环境与其他对流活动区MCC较少的大尺度环境的差异；(4)MCC的全球特征及其对全球水文循环的贡献。PIS期望提供对中尺度云和降水过程如何与其大尺度环境相互作用、促成和改变的了解。//

The four specific objectives to be defined are: (1) the role of melting and subcloud layer evaporation in the creation of lower tropospheric inverted troughs, (2) the effects of surface fluxes, melting, and lower tropospheric evaporation on the structure, circulation, and amplification of a vortex-bearing mesoscale convective system, (3) the differences between the large scale environment of regions that experience numerous mesoscale convective complexes (MCCs) and the environment of other convectively-active regions where MCCs rarely occur, and (4) the global characteristics of MCCs and their contribution to the global hydrologic cycle. The PIs expect to provide understanding of how mesoscale cloud and precipitation processes interact with, contribute to, and change their large scale environment.//
