Using the usual parameters, Typhoon does not perform as well on this simulation as it did with the previous experiments. See Experiment 7 for another attempt on the same data.
Typhoon command: ./cutyphoon_server -port 60000 -nM 7 -nD 8 -nE 8 -r 1 -a 0.01
This is a large eddy simulation (LES) using the NCAR-LES code on a domain of size (Lx,Ly,Lz) = (5120,5120,2048)m. The domain is periodic in the x and y directions and the boundary layer is initialized with a capping inversion at z = 1000m. The flow is neutrally stratified, with a geostrophic wind of 10 m/s. The grid size for the computations is 256x256x256. The horizontal slice shown in the image is taken at a height of z = 200m.
The above video shows the movement of the tracer in the simulation. The two images shown reflect the data passed to Typhoon; they are 15 seconds apart to match the time interval of the REAL hardware.
