Application of a New Spectral Theory of Stably Stratified Turbulence to the Atmospheric Boundary Layer over Sea Ice

A new spectral closure model of stably stratified turbulence is used to develop a K-D*e model suitable for applications to the atmospheric boundary layer. This K-D*e model utilizes vertical viscosity and diffusivity obtained from the spectral theory. In the D*e equation, the Coriolis parameter-dependent formulation of the coefficient C suggested by Detering and Etling is generalized to include the dependence on the Brunt-Vaeisaelae frequency, N. The new K-D*e model is tested in simulations of the ABL over sea ice and compared with observations from BASE as simulated in large-eddy simulations by Kosovic and Curry, and observations from SHEBA.
