Simultaneous Observations of Turbulent Reynolds Stress in the Ocean Surface Boundary Layer and Wind Stress over the Sea Surface

This study used high-frequency acoustic instruments mounted on an offshore observation platform to obtain simultaneous in situ measurements of sea surface winds and ocean currents. The acquired data were compare quantitatively the turbulent Reynolds stress boundary layer (OSBL) wind over surface. During period (∼10 d), state was largely dominated by swell breaking waves. eddy covariance method estimate two stresses. A combination synchrosqueezed wavelet transform (SWT) a moving average employed for wave-turbulence decomposition oceanic velocities. Results showed that OSBL is affected greatly gravity waves it scales with wave characteristics. Direct comparison revealed could be larger than certain circumstances, which differs from traditional view former cannot greater latter. In extreme cases, their ratio can up one order magnitude. Therefore, we conclude enhance significantly OSBL.
