在2010年春季第二次验证龙卷风旋转起源实验(VORTEX2)期间，安装在卡车上的移动和脉冲多普勒激光雷达系统[车载测风激光雷达设施(TWOLF)]与移动相控阵X波段多普勒雷达系统[移动天气雷达-2005 X波段相控阵(MWR-05XP)]一起被用来补充雷达-激光雷达设施附近晴空中的多普勒速度覆盖，并在晴空边界层附近和超级单体中提供高空间分辨率的多普勒风场垂直截面。认为垂直切变的大小和方向以及可能的边界层中卷曲的方向和间距对超级单体和龙卷风的行为都有显著的影响，MWR-05XP和TWOLF可以提供可用于测量垂直切变和探测卷卷的数据。然而，在整个洞穴深处，很少有详细的、与时间相关的和空间上变化的观测。
AbstractDuring the Second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2), in the spring of 2010, a mobile and pulsed Doppler lidar system [the Truck-Mounted Wind Observing Lidar Facility (TWOLF)] mounted on a truck along with a mobile, phased-array, X-band Doppler radar system [Mobile Weather Radar–2005 X-band, phased array (MWR-05XP)] was used to complement Doppler velocity coverage in clear air near the radar–lidar facility and to provide high-spatial-resolution vertical cross sections of the Doppler wind field in the clear-air boundary layer near and in supercells. It is thought that the magnitude and direction of vertical shear and possibly the orientation and spacing of rolls in the boundary layer have significant effects on both supercell and tornado behavior; MWR-05XP and TWOLF can provide data that can be used to measure vertical shear and detect rolls. However, there are very few detailed, time-dependent and spatially varying observations throughout the depth of the bou...
