The objective of this study is to analyse the current climate zone applied by Koppen climate classification and the future climate zone projected by the A2 scenario in Asia regions. The spatial and temporal variations of precipitation and temperature were also analyzed. As regards to the result of analysis on the variation of climate factor, temperature and precipitation will be increasing 4.0∘C and 12% respectively in the 2080s comparing with the reference period (1991~2010). Spatially, the range of temperature increase on the high latitude area is higher than that on the low latitude area. The precipitation will be increasing averagely in the overall area, but the spatial unequal distribution of precipitation will be intensified. At the result of the future climate zone, the area of warm climates will be increasing while the area of cold climates will be decreasing. In 2080s, the temperature will be increasing as much as 7.2% and 1.9% on the Tropical climates and Arid climates respectively, but it will be decreasing as -2.4%, -4.9% and -1.8% on the Warm temperate climates, Cold climates and Polar climates respectively. Furthermore, the part of Savannah climates and Desert climates will be mostly increasing. It is mainly caused by the temperature increase and desertification impact according to global warming.
