Large-Eddy Simulation #225: (Upwind)
LES RUN #225: Upwind simulation. Shear driven.
200 x 120 x 69 with 15-m resolution in all 3 directions.
Periodic lateral boundary conditions.
Entire domain over snow-covered land.
Arakawa & Lamb advection routine, VDKR=HDKR=0.05.
Horizontally homogeneous initial condition according to observations.
The initial temperature and dew-point profile was from the radiosonde and the
initial wind speed and direction profiles were from
linear fits to the data as shown in the first frame
of the animation (the thumbnail is the last frame of the animation.)

The following animation shows the
evolution of mean profiles (red lines) of wind speed, direction,
temperature and dewpoint as well as vertical velocity
on a east-west oriented vertical slice.
The following animation shows simulated lidar backscatter on a horizontal
plane 7.5 m above the surface.
The following animation shows simulated lidar backscatter on an
