The overall goal of the research is to use observationally- based data to better understand and predict hydrological and dynamical processes over the western Pacific Ocean and their interactions with adjacent areas. The main objective will be to prepare an atlas containing monthly means of several kinematic, thermodynamic, and hydrological variables over the tropical Indian and Pacific Oceans with an emphasis on the TOGA-COARE region. The atlas will use ECMWF analyses from the WCRP/TOGA archive II data set for 1985-1990, and should be completed shortly after the end of the intense observing period (IOP) of TOGA COARE. In subsequent years, a second atlas will be completed to include TOGA-COARE results for comparison. Other specific objectives are: to diagnose the horizontal and vertical structure of the intraseasonal oscillation as it traverses the Large-Scale Array (LSA) of TOGA- COARE; to investigate the relationship between enhanced tropical heating in the LSA and subtropical wind maxima over the western Pacific; and to examine a new method for improving estimates of heat and moisture transfer coefficients with the intent of improving estimates of sensible heat exchange and evaporation over tropical oceans. The research is important because it is one of the TOGA COARE studies to investigate the principal processes responsible for the coupling of the ocean and the atmosphere in an especially climate sensitive region of the world, the western Pacific Ocean, the field site of TOGA COARE.

研究的总体目标是通过观察- 更好地了解和预测水文和 西太平洋的动力过程及其 与邻近地区的互动。 主要目标是 准备一个地图集，其中包含几个运动学的月平均值， 热带印度洋上空的热力学和水文学变量 和太平洋，重点是TOGA-COARE地区。 的 地图集将使用ECMWF从WCRP/TOGA存档II数据中获得的分析结果 定于1985-1990年进行，应在1990年底后不久完成。 TOGA COARE的强烈观察期（IOP）。 在随后 2005年，将完成包括TOGA-COARE在内的第二个地图集 结果进行比较。 其他具体目标是： 诊断季节内的水平和垂直结构 振荡，因为它穿越大规模阵列（LSA）的TOGA- COARE;调查热带增强与 LSA的加热和西部副热带风极大值 以及审查一种新的方法， 热湿传递系数， 改进对1990 - 2000年期间感热交换和蒸发的估计 热带海洋 这项研究是重要的，因为它是TOGA COARE之一 研究调查的主要过程负责 在特定气候下海洋与大气的耦合 世界敏感地区，西太平洋，该领域 TOGA COARE网站
