摘要

Abstract

A non-hydrostatic

Boussinesq

and three-dimensional large eddy simulation (LES) model was used to study the impact of the Earth’s rotation on turbulence and the redistribution of energy in turbulence kinetic energy (TKE) budget. A set of numerical simulations was conducted

(1) with and without rotation

(2) at different latitudes (10°N

30°N

45°N

60°N

and 80°N)

(3) with wave breaking and with Langmuir circulation

and (4) under different wind speeds (5

and 30 m/s). The results show that eddy viscosity decreases when rotation is included

indicating that rotation weakens the turbulence strength. The TKE budget become tight with rotation and the effects of rotation grow with latitude. However

rotation become less important under Langmuir circulation since the transport term is strong in the vertical direction. Finally

simulations were conducted based on field data from the Boundary Layer and Air-Sea Transfer Low Wind (CBLAST-Low) experiment. The results

although more complex

are consistent with the results obtained from earlier simulations using ideal numerical conditions.
