Study on Influencing Factors of Sea-air CO2 Exchange Rate under Medium-high Wind Speed
Wave breaking and bubble are the key factors of gas exchange rate at medium and high wind speed.In this paper,the contribution of bubbles and non-broken parts is analyzed and calculated,and the influence of suspended matter concentration is considered in combination with the characteristics of tropical cyclones and coastal waters,so as to evaluate the role of organisms in gas exchange.The contribution of bubbles to the exchange rate at medium and high wind speeds is 55%～76%.The overall contribution of the concentration of suspended matter to the exchange rate is second only to that of the bubble,which is 11%～19%.The biological carbon cycle process affected by the increase of suspended matter concentration is very important,and the research results can provide a way to quantify the CO2 gas exchange at medium and high wind speed.
