This study is to promote modeling activities relating to TOGA (Tropical Ocean and Global Atmosphere) / NEG (Numerical Experimentation Group) under WCRP (World Climate Research Program). Thus it covers all international members of TOGA/NEG and active GCM (General Circulation Model) modellers in Japan.During the first year, using an OGCM, we identified the mechanism of warm water accumulation prior to ENSO events in the western Pacific. Also, we could simulate the detailed seasonal evolution of the Costa Rica Dome for the first time in the world. In addition to those, we investigated intraseasonal disturbances and interactions among different space and time scales in the tropics.During the second year, we analysed the Mindanao Dome in detail and accelerated the international efforts toward investigating the role of low-latitude western boundary currents on the short-term climate variability. On the other hand, we discussed the role of a deep sea circulation on the long-term climate varia … More bility. The latter is to connect smoothly the present study with a future program which will treat of interdecadal climate variabilities.During the final year we had a cooperative project of ocean model intercomparison with foreign institutions. The result was quite promising and our models were ranked high in the world community. MRI (Meteorological Research Institute) also finished constructing its high-performance coupled ocean-atmosphere GCM. This coupled GCM is now one of the leading models in the world community. All those are the outcome of the active cooperation with generous foreign members under the present program. In order to summarize our project we held an international symposium on climate changes and the ocean successfully in Tokyo under the support of the Science Council of Japan, the Oceanographic Society of Japan and the Meteorological Society of Japan.On the basis of the present study, we are now going to establish a new international program which focuses on the interdecadal climate variabilities under CCCO (Committee on Climatic Changes and the Ocean) of IOC/SCOR.

这项研究旨在促进世界气候研究计划下与热带海洋和全球大气(TOGA)/数值实验组(NEG)相关的模拟活动。因此，它涵盖了TOGA/NEG和日本活跃的GCM(通用环流模式)模式的所有国际成员。在第一年，我们使用OGCM，确定了ENSO事件之前西太平洋暖水积累的机制。此外，我们还可以在世界上第一次模拟哥斯达黎加穹顶的详细季节演变。在第二年，我们对棉兰老岛穹顶进行了详细的分析，并加快了研究低纬西部边界流对短期气候变率的作用的国际努力。另一方面，我们讨论了深海环流对长期气候变化…的作用。更多的能力。后者是为了使目前的研究与未来处理年代际气候变化的计划顺利衔接。在最后一年，我们与国外机构进行了海洋模式比对的合作项目。结果是非常有希望的，我们的模型在国际上排名很高。MRI(气象研究所)也完成了其高性能海洋-大气耦合GCM的建造。这种耦合的GCM现在是国际上领先的模式之一。所有这些都是在本计划下与慷慨的外国成员积极合作的结果。为了总结我们的项目，在日本科学委员会、日本海洋学会和日本气象学会的支持下，我们在东京成功地举办了气候变化与海洋国际研讨会。在本研究的基础上，我们将在IOC/SCOR气候变化和海洋委员会(CCCO)下建立一个新的以年代际气候变化为重点的国际计划。较少
