对Glover et al提出的基于双频卫星高度计的海面粗糙度与气体传输的关系模式进行改进,增加了化学增强效应对气体传输速率的影响。并以中国海及西北太平洋海域为例得到2002年化学增强效应的月平均影响分布。研究显示:1月影响最小,约为0.6%;6月影响最大,约为5.8%。利用作者提出的改进算法得到CO2气体传输速率的全球分布,对分布特征进行了分析。在部分热带海域(0°~10°N,130°E~150°E),对基于海面粗糙度的算法和基于海面风速的2种典型算法分别进行了冬、夏2季节的比较,发现海面风速较大(>5 m/s)时,基于海面粗糙度的算法得到的结果小于基于海面风速的估算结果;海面风速较小(<5 m/s)时,基于海面粗糙度的算法得到的结果介于2种基于海面风速算法的结果之间,对原因进行了分析。在该海域,化学增强效应的影响在夏季会达到31.98%。
The improvement of the relationship between the sea surface roughness and the gas transmission based on the dual-frequency satellite altimeter proposed by Glover et al increases the influence of chemical strengthening on the gas transmission rate. Taking the China Sea and the Pacific Northwest Pacific as an example, we obtain the monthly average distribution of the effects of chemical intensification in 2002. The study showed that: the impact of January minimum, about 0.6%; June the impact of the largest, about 5.8%. Using the improved algorithm proposed by the author, the global distribution of CO2 gas transmission rate is obtained, and the distribution characteristics are analyzed. In some tropical sea areas (0 ° ~ 10 ° N, 130 ° E ~ 150 ° E), two typical algorithms based on sea surface roughness and sea surface wind speed were respectively compared in winter and summer and found that sea surface When the wind speed is high (> 5 m / s), the sea surface roughness-based algorithm results are less than those based on the sea surface wind speed estimates. When the surface wind speed is small (<5 m / s), the sea surface roughness- The result is between the two results based on the sea surface wind speed algorithm, and the reasons are analyzed. In this area, the effect of chemical strengthening effect will reach 31.98% in summer.
