Turbulent structures in the Marine Atmospheric Boundary Layer
(Meteorologi, AWEP)
2010 (English)Other (Other (popular science, discussion, etc.))
Abstract [en]

Most atmospheric models such as weather forecast models and climate models are dependent on the turbulent exchange of momentum and scalars (heat, CO2 …) at the air-sea interface. These exchange processes are often described by simplified bulk formulas describing the average effects of complicated turbulent structures which are presently only partly understood.

A numerical technique called large eddy simulation (LES) can be used to reveal certain aspects of the dynamics of the turbulent atmospheric boundary layer towards a better understanding and representation of the governing processes. We will attempt to explain some of the mechanisms (sources) of turbulence and visualize some of the dominant structures obtained from LES under different atmospheric conditions/forcing.
