CO_2浓度渐增对气温影响的敏感性试验

SENSITIVITY TEST CONCERNING WINTER TEMPERATUKE RESPONSE TO GRADUAL INCREASE IN CO_2

使用辐射对流模式，研究了中纬度冬季气温对于ＣＯ＿２浓度变化的敏感性。结果表明：气温变幅随ＣＯ＿２浓度渐增呈现先快后慢的非线性特征；气温变幅具有一定的稳定性。

A radiative-convective model is developed to examine the sensitivity of winter midlati-tude warming in relation to increasing CO_2 amount.Results show that i)the temperature changeexhibits a nonlinear growth,faster initially and slow afterwards,under progressive increase of thegas;ii)the mean temperature amplittide displays some degree of stability.
