Abstract Based on airsea flux data from a meteorological gradient tower in the Xisha waters of the South China Sea from June to October 2023,the article analyzes the variation characteristics of surface momentum,sensible heat,and latent heat fluxes,as well as their correlations with wind speed and relative humidity.Results indicate that momentum flux exhibits minimal diurnal variation,with October values doubling those of other months,while sensible and latent heat fluxes share similar diurnal patterns peaking at noon,with latent heat significantly exceeding sensible heat.Notably,latent heat flux is negatively correlated with wind speed,whereas sensible heat flux shows a positive correlation,and both heat fluxes are negatively correlated with relative humidity.Furthermore,the region acted as a carbon source with positive daily mean fluxes from June to July and in September,but shifted to a weak carbon sink with negative daily means in October.These findings enhance the understanding of diurnal airsea flux processes and mechanisms,providing scientific support for studying the airsea energy balance in the South China Sea.
