Comparison of Large Eddy Simulations of a convective boundary layer with wind LIDAR measurements

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...
