COLLABORATIVE RESEARCH: Boundary Layer Processes During STORM-FEST

格罗斯曼计划在1992年的STORMFEST实验中，将来自不同遥感平台的数据与更传统的数据和湍流通量测量相结合。STORMFEST的主要科学目标是：第一，实地测试新的中尺度观测和预报系统，为美国天气研究计划后来的主要实地实验做准备；第二，研究冬季锋面和降水天气尺度气流的中尺度结构。他的目标是定量描述在更大规模的实验阵列中嵌套的50公里正方形内的行星边界层(PBL)的结构。这些数据将提供在不同云层覆盖的各种气象情况下的日循环通量和轮廓的估计。该数据库以后可以被其他研究人员与其他实验(数值大涡模拟)数据结合使用，以比较评估目前在GCM和气候模式中使用的各种PBL参数，并希望导致这些参数的改进版本。

Grossman plans to combine data from different remote sensor platforms with more conventional data and turbulent flux measurements in the 1992 STORMFEST experiment. STORMFEST's primary scientific goals are first, to field-test new mesoscale observing and forecasting systems in preparation for later major field experiments of the U.S. Weather Research Program; and second, to study the mesoscale structures of winter frontal and precipitation synoptic scale flow in which they are embedded. His objective is to quantitatively describe the structure of the Planetary Boundary Layer (PBL) in a 50-km square nested within the larger scale experimental array. The data will provide estimates of fluxes and profiles over the diurnal cycle, in a variety of meteorological situations, with varying cloud cover. The database can later be used by other investigators in conjunction with other experimental (numerical large-eddy simulation) data to comparatively evaluate the various PBL parameterizations currently in use in GCM and climate models, and, it is hoped, lead to improved versions of these.
