Newsletter No.7 July-1999�@

Dr.Yoshio Kurihara   I enjoy working at the Integrated Modeling Research Program since December last year. As is well understood,progress in research using numerical simulation models depends on three 'ware's,i.e., the brainware of the researchers,software and hardware. I wish to make a contribution to the development of an integrated climate model consisting of component models of the atmosphere, ocean, land and biosphere as well as models of hydrological and chemical processes connecting these components. Themodel has to be properly suited to the Earth Simulator.I have performed numerical studies on hurricanes at NOAA/GFDL after 1970, made an effort for 10 years after 1986 to convert the research model to a hurricane prediction system, and transferred it to the U.S. Weather Bureau for official operational use. Hopefully, such an experience will serve in my future modeling activities. In addition, I am very much interested in studies on the cloud behavior which is an important process in the climate system. Dr.Keiko Takahashi   I joined the Integrated Modeling Research Program on September 16,1998. My specialization is in the field of computer science. I have been researching on parallel computing models of large scale and complexity, which do not always need synchronous computing, and have been studying the themes "To which class of problems can we get solutions?"or "which restrictions are required to obtain the solutions accurately and effectively ?" My participation in the Frontier is from quite a different field. However, the Earth's climate system, which is at the top of a complex system is a very attractive research for me from the view point of computing science.I suppose that by understanding various characters reflected to numerical calculation, we can, not only contribute to computing sciences, but also offer much info rmation to the numerical calculation technique of the atmosphere or ocean general-circulation models.   By this time,I have shown adequacy of a vertical one-dimension ocean model with upwelling velocity depending on the depth by carrying out numerical calculations of ��14C profiles for each of the three big oceans. At present, I am engaged in the works on high resolution of NJR ocean general-circulation model, and on their numerical experiments.In the future,I intend to perform numerical calculations including data assimilation techniques, and also make efforts in parallel computing, keeping calculation on the Earth simulator in mind.   I would like to continue to give a challenge vigorously to new creation in this field by the tight cooperation with the experts and the researchers in this and the other fields.
