Here we applied Typhoon to the temperature field of the LES simulation detailed below. See Experiment 4 to see Typhoon applied to passive tracer data from the same simulation.
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 forced with a geostrophic wind of \(10 m/s\) and a surface heat flux of \(0.5 W/m^2\). The grid size for the computations is \(256\times 256\times 256\). The horizontal slice shown in the image is of a passive conserved scalar taken at a height of \(z = 20m\). The scalar concentration is set to \(1\) at the bottom surface.
The above video shows the movement of the temperature field 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.
