CS计算机代考程序代写 database 降雨对海-气界面CO2交换的影响研究

降雨对海-气界面CO2交换的影响研究 思路:利用文献翻译中的公式(3)计算海-气界面间的CO2交换通量。其中k是大气和海洋间的气体交换系数;代表某温盐条件下CO2的溶解度。 目前关于海一气间气体交换系数的计算模式较多, Liss等根据风浪槽和实验数据提出了一种气体交换速率与风速的线性分段参数化方案。该方案根据海面以上10米处风速的大小将海面状况分为三个阶段:每一个阶段对应一个不同的函数关系式,其具体表达式为: 其中,表示 CO2在20°C淡水Sc=600时的气体交换速率,单位为cm/h;风速的 单位为m/s,该参数化方案简称为LM。 Wanninkhof等根据风浪槽实验结果进行数据拟合,得到了气体交换速率与风速的平方成正比的函数关系。Wanninkhof利用全球天然和核爆炸数据和红海核爆炸数据确定了系数,即 该参数化方案简称为WA。 Nightingale等在北海南部沿岸海域进行双气体示踪实验,实验数据显示,气体交换速率与风速有十分明显的相关关系。利用观测数据进行拟合,得到了气体交换速率和风速的函数关系式: 该参数化方案简称为NI。 McGills等在北大西洋使用涡相关法测量海-气界面CO2通量,然后利用块体参数化公式计算出了气体交换速率,结果发现中低风速下涡相关法的测量结果较好,但是风速大于12m/s时,涡相关法的测量结果较大。根据观测数据并考虑波浪破碎对气体交换速率的影响,他们提出了气体交换速率与风速的立方成比例的函数关系式: 该参数化方案简称为MC。 还包括其中Wanninkhof (1992)提出的模式比较合理,应用比较广泛,公式如下: 对于长期平均风: 对于瞬时风: (Relationship between gas exchange and wind speed over the ocean)Wanninkhof (1992) 【对于上述不同的风速公式进行比较,择优选取一个使用】 代表在海水温度为t(°C)时的施密特数 的计算公式如下(Carbon dioxide in water and seawater : the solubility of a non ideal gas)(Weiss,1974): 式中T为热力学温度,单位K。T(K)=t(°C)+273.15 当的单位是Mole/*atm时。常数、、、、、的取值分别是: -58.0931 90.5069 22.2940 0.027766 -0.025888 0.0050578 当的单位是Mole/kg*atm时。常数、、、、、的取值分别是: -60.2409 93.4517
