Large-Eddy Simulation #143: TIBL
LES RUN #143: TIBL.
This is our first attempt at simulating the transition from a shear-driven
turbulent flow to a heat-driven turbulent flow. Previous TIBL simulations
were laminar flow (i.e. no large-eddies in the flow upwind of the lake) to
turbulent flow transitions.
This domain is 12 km (east-west) by 750 m (north-south) wide by 1.0 km
tall. The horizontal and vertical resolution is 15 m in all directions.
The left 6 km is over land and the right 6 km is over the lake.
The flow is from the NW with a 400 m deep mixed layer.
The west wall of this domain is perturbed by adding a random number
between + and - 0.5 m/s to the v-component of flow below 400 m on each
time step. This is done to speed the development of a shear-driven
mixed layer over the land before the air advects over the water.
