从以下几个方面简要分析了海—气间化学物质交换通量的参数化研究情况:如果不考虑物质间的化学反应,经典的通量-梯度关系(K理论)可用于估计从大气进入海表面的物质通量。在有化学反应的情形下,应根据化学反应速度与湍流交换速度的相对大小对K理论做修正;已知海表面的物质浓度和物质的沉降速度,可由二者的乘积来估计通量的大小。降水对大气中物质的清除作用是很大的,如何对降水的物理过程进行参数化,直接影响到对湿沉降通量的估计;计算海—气间气体交换通量的一种方法是利用界面两侧的分压差和气体转移系数。这两个参数都可能造成通量估计的不确定性。
The following is a brief analysis of the parametric study of the exchange fluxes of sea-air chemicals: The classic flux-gradient relationship (K-theory) can be used to estimate the atmospheric flux from the atmosphere into the sea without considering the chemical reactions between species Surface material flux. In the case of a chemical reaction, K theory should be modified according to the relative magnitude of chemical reaction velocity and turbulent exchange velocity. It is known that the mass concentration of the sea surface and the sedimentation velocity of the material can be estimated by the product of the two fluxes . The effect of precipitation on the removal of atmospheric substances is very large. How to parameterize the physical process of precipitation directly affects the estimation of wet deposition fluxes. One method to calculate the gas exchange fluxes between sea and air is to use the interface Differential pressure on both sides and gas transfer coefficient. Both of these parameters can contribute to the uncertainty of the flux estimate.
