Analyses and Assimilation of COARE Doppler Radars and LidarsData

该项目包括对将在TOGA/COARE密集观察期部署的多普勒雷达的数据进行分析和同化。分析将着重于海洋边界层中动量和热通量的计算。同化将着重使用来自所有可用的多普勒雷达的数据，并结合新开发的多普勒雷达同化技术，以构造TOGA/COARE强通量区(IFA)对流复合体的形态和通量。该方法的关键是从多普勒雷达资料和动力学模式的合理融合中恢复完整的三维风场和温度场。这项研究之所以重要，是因为它是TOGA COARE研究之一，它将对流尺度的物理过程与影响世界上一个特别气候敏感区域--西太平洋--TOGA COARE现场的气候变异性的较大尺度联系起来。

This project comprises the analysis and assimilation of data from the Doppler radars that will be deployed during the TOGA/COARE Intensive Observing Period (IOP). The analysis will emphasize the calculation of momentum and heat fluxes in the marine boundary layer. The assimilation will emphasize the use of data from all available Doppler radars in combination with newly developed Doppler radar assimilation techniques to construct the morphology and fluxes by convective complexes in the TOGA/COARE Intensive Flux Area (IFA). The crux of the method is the recovery for the full three-dimensional wind and temperature fields from a judicious blending of Doppler radar data and a dynamical model. This research is important because it serves as one of the studies of TOGA COARE that links convective scale physical processes to the larger scales that impact climate variability in an especially climate sensitive region of the world, the western Pacific Ocean, the field site of TOGA COARE.
