This is a Small Grant for Exploratory Research to support participation in the DYCOMS-II project scheduled for July 2001. DYCOMS (Dynamics and Chemistry of Marine Stratocumulus) is a study of mixing processes in stratocumulus clouds in the marine boundary layer off the coast of California. The main objective is to obtain high-resolution aircraft data (using the NCAR C-130) on temperature, humidity, vertical air velocity, and cloud properties, that can be used for validating large-eddy simulations of the boundary layer. The ultimate goal is to improve the parameterization of cloud-top mixing processes in large-scale models of atmospheric circulation and climate. Dr. Lilly will participate in the planning and field work of DYCOMS and use the experiments as an opportunity to evaluate a theoretical model for entrainment mixing that he has recently developed. This study will complement the main DYCOMS plan, which is to reconcile the observations of turbulent mixing with large-eddy simulations.

这是一笔用于探索性研究的小额赠款，用于支持参与定于2001年7月进行的DYCOMS-II项目。DYCOMS （Dynamics and Chemistry of Marine Stratocumulus）是一项研究加利福尼亚海岸外海洋边界层层积云混合过程的研究。主要目标是获得高分辨率的飞机数据（使用NCAR C-130），包括温度、湿度、垂直空气速度和云特性，这些数据可用于验证边界层的大涡模拟。最终目标是改进大尺度大气环流和气候模式中云顶混合过程的参数化。Lilly博士将参与DYCOMS的计划和现场工作，并利用实验作为评估他最近开发的夹带混合理论模型的机会。这项研究将补充DYCOMS的主要计划，即将湍流混合观测与大涡模拟相协调。
