| 摘 要： | 作者用大气物理所全球大气环流模式耦合混合层海洋模式模拟了大气中CO_2含量增加一倍后对全球气候的影响,本文集中讨论对中国气候的影响。初步结果表明:中国气温增高幅度在南方和东北较大,夏季增温较冬季增温大;降水变化较为复杂,季节差异也很大,总的讲是东北大部、河套一带及云南、广西降水减少;土壤湿度在大部分国土上是变小的,这可能会引起严重的农业和生态负效应。

| Abstract: | The IAP atmospheric general circulation model was coupled to a 60 meter deep mixed layer ocean model and the simulation of climatic changes induced by a doubling of CO_2 content in the atmosphere was done by using this coupled model. We concentrate in discussing the climate change in China. It is pointed out that the temperature increase is greater in southern China and the north-east than in other regions and that the temperature increase is greater in summer than in winter. We noticed that there are great difference of precipitation change between different regions and between different seasons. Generally, precipitation decreases in most part of north-east,in Hetao region and in Yunnan and Guangxi. It might bring about serious agricultural and ecological effects that soil in most part of China will become drier as CO_2 increases. |
