摘要
使用IPCC第四次评估报告中多模式集合的预估产品,在A1B情景下,对21世纪河南省未来90年的月平均气温、降水的变化趋势及时空分布进行预估。与1971～2000年30年气候平均相比,在未来的90年,河南省平均气温呈上升趋势,且南部增温大于北部,气温的增幅随时间变化减弱;降水呈现从南向北增加的趋势,降水量的变化不太显著。
Using the monthly temperature,precipitation of IPCC Fourth Assessment Report of the muti-model from National Climate Center,we do some research on the trends of monthly temperature and precipitation＇s temporal and spatial distribution in the 21 century.Compared to average data from 1971 to 2000,the monthly temperature has a warming tendency in the next 90 years,and it will increase more quickly in the south than in the north area.The change rate of temperature will decrease over time.The monthly precipitation will perform the increasing tendency from the south to the north part of Henan Province for the spatial distribution,but for the temporal distribution it will not increase significantly.
