Abstract:

基于卫星资料建立的CCMP风场、ECMWF波浪和最新CO2分压数据,分别用4种以风速为单参数和2种包含海况影响的双参数气体交换速率公式,估算了全球海-气CO2通量,发现前者的结果比后者平均小30%左右,从整体上看,与单参数公式相比,双参数公式使得海洋中CO2源和汇的强度均明显增强。在此基础上,讨论了时间平均尺度对海-气CO2通量估计的影响,结果表明,标量平均法比矢量平均具有更好的稳定性,但依然使得短时间平均比长时间平均得到的CO2通量值要大,月平均与6h平均相比,单参数公式和双参数公式分别使海洋的净吸收量减少33%和5%,说明双参数公式具有较好的稳定性。研究还发现,1988-2009年间,全球平均风速有增大的趋势,2006年前后出现一个极大值,但相应的CO2年净通量基本保持稳定,甚至其绝对值有所减小、海洋的吸收能力减弱的倾向。
