| 摘 要： | 通过在海洋上混合层温度方程的平流输运项中加入Stokes漂的影响,定量计算了波浪Sokes漂对混合层温度变化的贡献,即Stokes漂对SST变化的影响。结果表明,波浪Stokes漂的平流输运作用对混合层温度变化的贡献与平均流的贡献在量值上处于可比的量级,二者全球平均比值为23.43%,最大比值达到70%。而对于SST变化率的影响也较为显著,加入Stokes漂影响后,SST变化率的最大变化值达到0.989×10-6℃/s,SST变化率的全球平均变化值为0.077 8×10-6℃/s,与SST变化率全球平均量值0.516 2×10-6℃/s相比达到15.07%,是不可忽略的。因此,在对于海洋混合层温度计算过程中,考虑波浪Stokes漂的作用是必要的。

| Abstract: | Adding the influence of Stokes-drift to the advection transport of mixed layer temperature equation to caculate the contribution of Stokes-drift to the mixed layer temperature alteration rate.That is also the contribution to the alteration rate of SST.The results show that the effect of Stokes-drift and the effect of mean current to mixed layer temperature alteration are on a comparable magnitude,the global mean ratio of the two components is 23.43%,and the biggest ratio reach to 70%.In addition,for the total rate of SST change,the effect of Stokes-drift is also remarkable.After adding the effect of Stokes-drift,the changing of globle mean SST alteration rate is 0.0778×10-6℃/s,and the maximum changing reach to 0.989×10-6℃/s,compare to the global mean value of SST alteration rate 0.5162×10-6℃/s,the changing reach to 15.07%,that should not be ignored.Therefore,it is necessary to add the effect of Stokes-drift into the caculation of temperature in mixed layer. |
