Stability of Boundary Layer Flow.

Abstract

A technique is developed and applied for the evaluation of conditions under which marine boundary layers are unstable, and for computing the rate of growth of unstable motions. Linear perturbation equations are formulated which account for influence of wind shear, static stability, Coriolis force, turbulent diffusion, large-scale convergence, and geostrophic wind on linear stability. The mean quantities can be prescribed by analytic functions or supplied as numerical tables derived either from observed/specified data or a boundary layer model. The linearized model is solved as a generalized eigenvalue problem. Related calculations with the SIGMET code are discussed, including radar properties of the marine boundary layer. (Author)
