摘要：
Turbulence measurements within an artificially generated turbulent patch embedded in a stratified shear flow are presented. The results indicate that the enhanced patch growth that has been observed at background gradient Richardson numbers on the order unity can be attributed to the onset of shear-induced mixing at the patch boundaries rather than enhanced interaction between turbulence and shear that causes increased turbulence levels within the patch.
