The impact of sea waves on turbulent heat fluxes in the Barents Sea according to numerical modeling

Abstract. This paper investigates the impact of sea waves on turbulent heat fluxes in Barents Sea. The Coupled Ocean–Atmosphere Response Experiment (COARE) algorithm, meteorological data from reanalysis and wave WAVEWATCH III model results were used. calculated using modified Charnock parameterization for roughness length several parameterizations that explicitly account parameters. A catalog storm events a extreme cold-air outbreaks over Sea created used to calculate during events. important role energy exchange between atmosphere is demonstrated. high correlation was found number outbreak days sensible latent heat, as well with net flux longwave radiation averaged ice-free surface cold season. differences long-term mean values different are small average 1 %–3 % magnitude. Taylor Yelland (2001) Oost et al. (2002) lead an increase magnitude average, Drennan (2003) leads decrease entire compared parameterization. their exceed by factor 2. However, effect accounting parameters is, multidirectional, depending length. With respect climatic aspect, it can be argued calculations neglected. simultaneously observed outbreaks, sensitivity increases along transfer increase. In some cases, storms difference exceeds 700 W m−2.
