Observed Growth of Langmuir Circulation
Surface velocity patterns and upper ocean density profiles are presented from a period following a sudden increase in wind. A prior wind speed of 8 m/s failed to produce visible signs of Langmuir circulation. After the wind speed increased to 13 m/s, Langmuir circulation developed within 15 min. The initial scale observed was about 16 m, streak to streak, and may have been restricted by the dep...
متن کاملEvolution of Langmuir circulation during a storm
Wind stress, waves, stratification, velocity profiles, and surface fields of radial velocity and acoustic backscatter intensity were measured along a drift track 50 to 150 km off Point Arguello, California. On March 8, 1995, the wind increased from calm to 12 rn/s from the SE, opposing swell from the NW. It increased to15 rn/s at noon UTC on March 9, remained steady over the next 12 hours, brie...
متن کاملNonlocal transport due to Langmuir circulation in a coastal ocean
[1] We present observations and simulations of large-scale velocity structures associated with turbulent boundary layer dynamics of a coastal ocean. Special purpose acoustic Doppler current profiler measurements revealed that such structures were frequently present, in spite of complex coastal environmental conditions. Large eddy simulation results are only consistent with these observations if...
متن کاملObservations and Theories of Langmuir Circulation: A Story of Mixing
The study of Langmuir circulation has a strongly interdisciplinary history; the first half of this work is a brief and eclectic review of this. Much of the research has been motivated by interest in the biology and chemistry of the mixed layer. These, in turn, are sensitive to details of typical particle trajectories; i.e., to high-order statistics of the flow such as time and space lagged cova...
متن کاملObservations of Langmuir Circulation, Waves and the Mixed Layer
Abstract. Doppler sonar observations of surface velocity are analysed to extract an rms velocity scale related to flow patterns persisting for at least a minute, and having advection velocities within an adjustable "window" of the mean advection rate. The resulting velocity scale is related to the wind and waves over the course of the twenty days available from the SWAPP data set. The correlati...
