【摘要】 本文采用NCAR气候系统模式CSM 1.4研究了冬季风对强外辐射强迫变化的响应,其中外辐射强迫直接由太阳常数的变化而引入。结果表明:随太阳常数的增加,局地的增温幅度变化很大,中高纬地区比低纬地区增暖幅度强,这在太阳常数增加较大的试验中表现更为明显;随太阳常数增大越大,大气温度升高越高,对流层有强烈增温,对流层高层尤为显著,平流层中上层有降温现象;随太阳常数增大,亚洲冬季风系统的响应越强,系统强度增强明显,但形式不同,500 hPa随纬度增高增强幅度变大,100 hPa随纬度增高增强幅度变小。更多还原

【Abstract】 Using NCAR CSM Version 1.4,Asian winter monsoon’s response to the varies of the powerful external radiation forcing(counterpart of the solar constant changing) is observed,results show that: i) local temperature increasing with the solar constant increasing,temperature in mid-higher latitude areas is higher than that of in lower,that is more obvious in big solar constant experiment;ii) air temperature is adding with the solar constant,troposphere’s temperature is enlarging violenced,especially on high layer,but mid-higher stratosphere temperature decreasing;iii) the response of Asian winter monsoon enhancing with solar constant,and the bigger of the solar constant,the higher of the highs,but for different experiments,the echoes are different,the intensity growing range of high with latitude is great(little)at 500hPa(100hPa).更多还原
