Abstract

Recent theoretical and computational developments show that a layer with strong shear may act as a barrier for eddies to penetrate through this layer, provided the horizontal velocity of the eddy is not far from that of the mean flow and the size of the eddy is appropriate. Analysis of atmospheric surface layer data from two marine sites indicates that this effect may explain observed reduction of spectral energy within a wide frequency range in situations when a low-level wind maximum is present.
