A Sensitivity Analysis of the Impact of Rain on Regional and Global Sea-Air Fluxes of CO2

摘要: The global oceans are considered a major sink of atmospheric carbon dioxide (CO2). Rain is known to alter the physical and chemical conditions at sea surface, thus influence transfer CO2 between ocean atmosphere. It can gas exchange through enhanced velocity, direct export from atmosphere ocean, by altering skin temperature, surface layer dilution. However, date, very few studies quantifying these effects on net sea-air fluxes exist. Here, we include terms for velocity in calculations fluxes, using 7-year time series monthly climate quality satellite remote sensing observations, model in-situ data. use non-linear relationship rain wind significantly reduces estimated impact rain-induced turbulence rate transfer, when compared linear relationship. Nevertheless, globally, induced increase annual oceanic integrated up 6%. Regionally, variations be larger, with increasing Pacific Ocean 15% flux > ± 50%. Based analyses, impacts should included uncertainty analysis that estimate as have considerable impact, dependent upon region timescale.
