Large-Eddy Simulation #147: TIBL

LES RUN #147: TIBL. This domain is 12 km (east-west) by 1.650 km (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 animations shown are for a simulation that is 40-minutes long (frames are every 15-s).

The west wall of this domain is perturbed by adding a random number between + and - 0.5 cm/s to the v-component of flow for the bottom 3 grid-points 34-gridpoints east of the west wall. This is done to speed the development of a shear-driven mixed layer over the land before the air advects over the water.

The western boundary of this domain is "floating" which is specified by the variable INITIAL=1 in the NMSTASK file . It appears, when compared to LES #149, the this boundary condition causes east-west oriented features in the flow-field that can be eliminated by using the "fixed" boundary condition (INITIAL=3).
