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 ORLD气候研究计划的建模关系。，使用OGCM，我们还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，而在世界上，我们还可以在世界上模拟详细的季节性演变。研究了热带地区不同空间和时间尺度之间的季节内干扰以及相互作用。在第二年，我们详细分析了棉兰老岛的圆顶，并加快了国际努力，以研究低纬度西部边界电流的作用，我们讨论了。深海循环在长期气候中的作用...后来的账单是将目前的研究与未来的计划联系起来，该计划将处理婚礼的气候变化。模型学院的结果很高，我们的模型在世界上高的社区中排名很高。为了总结我们的项目，我们在日本科学委员会和日本气象学会的东京支持国际气候变化和东京的国际研讨会上。一项新的国际计划介绍了IOC/SCOR的CCCO（气候变化和海洋委员会）下的跨气候变化。
