We are developing the global climate model that simulates changes in the atmosphere, ocean, land and sea ice associated with climate changes such as the Global Warming, since 1980s at the Meteorological Research Institute.
|Fig. 1 Variations of the globally averaged annual-mean surface air temperature change simulated by the MRI global climate model (MRI-CGCM2.3.2) for the historical climate change experiment and the scenario experiments based on IPCC SRES (A1B, A2, and B2). The values are deviations from the average for years 1961-1990. Light colors denote the scatter range for the ensemble simulations.|
|Fig. 3 The simulated precipita- tion change in July for the 2081-2100 average in the SRES-A1B scenario experiment. The values are ratio (%) to the 1961-1990 average. Greens to blue colors indicate the regions of increase, and light to dark browns indicate the region of decrease. A precipitation increase around the Baiu frontal zone is projected.||Fig. 4 Three dimensional structure of the atmospheric temperature change in January for the 2081-2100 average in the SRES-A1B scenario experiment. The air temperature increases in the troposphere and decreases in the stratosphere with the global warming. The warming is large at the upper troposphere in the tropics and the lower troposphere in the northern high latitude. The atmospheric circulation changes in accordance with these three-dimensional temperature change with the global warming.|
