Comparison of Large Eddy Simulations of a convective boundary layer with wind LIDAR measurements
Vertical profiles of the horizontal wind speed and of the standard deviation of vertical wind speed from Large Eddy Simulations of a convective atmospheric boundary layer are compared to wind LIDAR measurements up to 1400 m. Fair agreement regarding both types of profiles is observed only when the s...

| description | Vertical profiles of the horizontal wind speed and of the standard deviation
of vertical wind speed from Large Eddy Simulations of a convective
atmospheric boundary layer are compared to wind LIDAR measurements up to
1400 m. Fair agreement regarding both types of profiles is observed only
when the simulated flow is driven by a both time- and height-dependent
geostrophic wind and a time-dependent surface heat flux. This underlines the
importance of mesoscale effects when the flow above the atmospheric surface
layer is simulated with a computational fluid dynamics model. |
