The following table shows the three basic shear cases for large eddy simulations (LES) on a 256x256x80 grid with cubic grid cells (5.12 x 5.12 x 1.6 km). The three cases are: SP00SH00 (surface geostrophic wind SPeed of 0 m/s with SHear of 0 m/s), SP00SH20 (surface wind SPeed of 0 m/s, SHear of the geostrophic wind of 20 m/s over the vertical domain), and SP20SH00 (surface wind SPeed of 20 m/s, SHear of the geostrophic wind of 0 m/s over the vertical domain).

The following table shows the convective boundary layer depth (zi), vs. time, for the three basic shear cases under different conditions of free atmosphere stratification (above the convective boundary layer). The surface buoyancy flux (expressed in terms of temperature) is allowed to have values of 0.03 K-m/s, 0.1 K-m/s, or 0.3 K-m/s. The vertical derivative of potential temperature has a value of 1 K/km, 3 K/km, or 10 K/km.
