Large-Eddy Simulation #190: (Upwind PBL)
LES RUN #190: Upwind shear & heat driven PBL over snow-covered land.
The simulation was initialized horizontally homogeneous according
to a radiosonde sounding 10-km west of the lidar site during Lake-ICE.
The domain is 200x120x69 grid-points with 15-m resolution in
all directions and 0.5 s time-step was used. The domain is
entirely over land and it has the same north-south dimension as
our largest TIBL runs (like #181). The grid is stationary and periodic in
the lateral directions.

The flow is from the NW with a 400 m deep mixed layer. The animations
shown are for about 3-hour simulations with over 600 frames each.
These are the longest animations we've made and were created using Matlab.
The following is a vertical slice through the model domain and
vertical profiles of the horizontal and vertical velocity components.
