Large-Eddy Simulation #262: (Lagrangian over water)


LES RUN #262: Periodic domain entirely over water started from the 30-minute solution to #252. The purpose of this simulation was to compare the turbulence statistics as a function of time with those from #260 as a function of offshore distance to test the hypothesis that the temporal evolution of the IBL is equivalent to the spatial evolution. 200 x 120 x 69 with 15-m resolution in all 3 directions. Arakawa & Lamb advection routine, VDKR=HDKR=0.05. Click here to see the NMSTASK file of LES #262.

The following animation shows the evolution of mean profiles (red lines) of wind speed, direction, temperature and dewpoint as well as vertical velocity on a east-west oriented vertical slice.




The following animation shows vertical velocity on 4 horizontal slices: 7.5, 97.5, 202.5 and 397.5 m above the surface.




The following animation shows simulated lidar aerosol backscatter at 7.5 m above the surface.




The following animation shows simulated lidar aerosol backscatter on an east-west vertical slice through the model domain.
