项目摘要

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.

这项研究是为了促进与Toga（热带海洋和全球气氛） / NEG（数字实验组）（世界气候研究计划）有关的建模活动。这涵盖了日本的Toga/neg和主动GCM（一般循环模型）模型的所有国际成员。在第一年，使用OGCM，我们确定了西太平洋事件发生在ENSO事件之前的温水机制。此外，我们可以在世界上首次模拟哥斯达黎加圆顶的详细季节性演变。除此之外，我们还投资了热带的不同空间和时间尺度之间的季节内惊喜和相互作用。在第二年，我们详细分析了棉兰老岛圆顶，并加速了国际努力，以调查低纬度西部边界电流在短期气候变异性上的作用。另一方面，我们讨论了深海循环对长期气候变量的作用……更质量。后者是将本研究与未来的计划顺利联系，该计划将处理婚礼中的气候变化。在最后一年，我们进行了海洋模型与外国机构的比较的合作项目。结果是很有希望的，我们的模型在世界社区中排名很高。 MRI（气象研究所）还完成了构建其高性能耦合的海洋 - 大气GCM。该耦合GCM现在是世界社区的主要模型之一。根据本计划，所有这些都是与慷慨的外国成员积极合作的结果。为了总结我们的项目，我们在日本科学委员会，日本海洋学会和日本气象学会的支持下成功举行了关于气候变化和海洋的国际研讨会。在本研究的基础上，我们现在将建立一个新的国际计划，该计划侧重于CCCO Inter CCCO（CCCO委员会委员会）（Climation Compartic Christation compartic Chreser/cameratic Carnecation/accaratic Careans ocareation/accaration/acce ocarative ocare）。较少的
