• Observation of Strong Wind Fields during Passage of Cold Front by Doppler Lidar

抄録

Field observation of wind fields has been carried out by using a doppler lidar and meteorological radars. Characteristics of fluctuational wind under cumulus convection and the growth of boundary layer including not only the effect of ground friction caused by surface roughness but also the effect of gust caused by up/down draft was examined and clarified. Some observed cases with the down flow under cumulus during passages of cold front were examined. The wind fields were simulated by large eddy simulation with canopy model, cloud physics model and boundary condition from simulated wind field by meteorological model WRF. The simulated wind fields consist with the observation. The wind speed near the ground increases with the down flow under the cumulus convection.
