An increasing greenhouse effect will lead to precipitation increasesmostly in north of 30°N for winter, and strongly increases alap a slant belt fromNortheast China to Bay of Bangal for summer in China. The mp of increasingprecipitation are about 7.9, -0.7 and 13.6 percent for winter, and 6.4, 12.9 and 8.4percent for summer m China, Changjinang and Huanghe river valleys, respectively.The model results are also shown to imply that an increasing greenhouse effectenhances chanas of intense storms and shown for winter and summer in China.展开更多

The change of temperature in the past 40 a is almost unanimous on the spatial scale. The first area becoming warmer is the southeastern Tibet. The plateau is divided into 5 parts according to the change of temperature, and 9 parts according to the change of precipitation. For the past 40a some area has been warmer and drier, others warmer and wetter.展开更多
