Surface Fluxes over the Warm Pool of TOGA-COARE

海气相互作用的研究需要地表动量、热量和水汽的通量。这项研究将使用一种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(传出长波辐射)和雨量计数据集的详细的“观测”降雨。强大的降雨算法在日场产生时校准地面实况的降雨率。在一个高分辨率数值预报模式的初始化过程中，利用一系列反向物理参数化算法得到通量。这种物理初始化技术是确定地表通量的最强大和最一致的程序之一。西太平洋暖池区的通量将在1987年1月开始的五年期间确定。此外，这项研究将包括对在TOGA COARE观测计划期间获得的下列通量进行详细比较和关键评估：a)大量空气动力通量，B)基于地表相似理论并根据需要对低/高风速和自由对流极限进行修正的通量，C)基于上面讨论的物理初始化技术的通量，D)基于NMC(国家气象中心)业务预报模型的通量，E)基于欧洲中期天气预报中心(ECMWF)业务预报模式的通量。这项研究之所以重要，是因为它是TOGA/TOGA COARE研究之一，在TOGA COARE方案的实地地点西太平洋这一世界气候特别敏感地区影响气候变异性的物理过程的数值表示的背景下，研究海-气相互作用，特别是地表通量。

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.
