LES Data



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 strongly convective, forced with a surface heat flux of 0.75 \(W/m^2\) and a geostrophic wind of 5 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 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.
