Surface Fluxes over the Warm Pool of TOGA-COARE

海气相互作用的研究需要动量、热量和水分的表面通量。这项研究将通过使用复杂的物理初始化程序来确定这些通量，该程序调用基于SSMI（特殊传感器微波仪器）、OLR（外发长波辐射）和雨量计数据集的详细“观测”降雨。强大的降雨算法校准地面真实的降雨率，因为每天的田野产生。在高分辨率数值预测模型的初始化过程中，利用一系列反向物理参数化算法获得通量。这种物理初始化技术是确定表面通量的最强大和最一致的方法之一。将从1987年1月开始确定西太平洋暖池区域的五年期通量。此外，本研究将包括对TOGA COARE观测项目中获得的以下通量的详细比较和批判性评估：a)整体气动通量；b)基于表面相似理论的通量，并根据需要对低/高风速和自由对流极限进行修正；c)基于上述物理初始化技术的通量；d)基于NMC业务预报模式的通量；e)基于ECMWF（欧洲中期天气预报中心）业务预报模式的通量。这项研究很重要，因为它是TOGA/TOGA COARE研究之一，在影响世界上一个特别气候敏感地区——西太平洋气候变率的物理过程的数值表示的背景下，研究海气相互作用，特别是表面通量。西太平洋是TOGA COARE项目的实地地点。

Air-sea interaction studies require surface fluxes of momentum, heat and moisture. This research will determine these fluxes by using a sophisticated physical initialization procedure that invokes detailed "observed" rain which is based on a mix of SSMI (Special Sensor Microwave Instruments), OLR (Outgoing Longwave Radiation), and rain-gauge data sets. The powerful rainfall algorithm calibrates the rain rates for ground truth as the daily fields are produced. The fluxes, in turn, are obtained by using a series of reverse physical parameterization algorithms within the initialization of a high resolution numerical prediction model. This physical initialization technique is one of the most powerful and consistent procedures for determining surface fluxes. Fluxes for the western Pacific warm pool region will be determined for a five year period starting in January 1987. In addition, this research will include a detailed comparison and critical evaluation of the following fluxes obtained during the TOGA COARE observation program: a) Bulk aerodynamic fluxes, b) Fluxes based on surface similarity theory and corrected as needed for low/high wind speeds and the free convection limit, c) Fluxes based on the physical initialization technique discussed above, d) Fluxes based on the NMC (National Meteorological Center) operation forecast model, e) Fluxes based on the ECMWF (European Centre for Medium-range Weather Forecasting) operational forecast model. This research is important because it is one of the TOGA/TOGA COARE studies that investigates air-sea interactions, particularly surface fluxes, in the context of the numerical representation of the physical processes that impact climate variability in an especially climate sensitive region of the world, the western Pacific Ocean, the field site of the TOGA COARE program.
