Gravity Wave 1-leat Fluxes: A Lagrangian Approach

摘要: Abstract The effect of a vertically propagating, internal gravity wave on the vertical flux potential temperature (heat) is considered by averaging local heat vector over surface. This approach gives simple physical picture which not readily apparent from more common Eulerian formulation. method also allows eddy diffusion coefficient to be function phase wave. Such dependent has been previously an viewpoint as model convectively unstable Here, Lagrangian confirms and corrects results. Earlier work extended modeling constant amplitude “breaking” wave, well considering coefficients that are asymmetric with respect breaking region. In all cases studied, 1ocalizing region wayebreaking decreases average flux.
