Low stratospheric zero wind layer measurement with Rayleigh Doppler lidar

Wind field is measured with a mobile Rayleigh Doppler Wind Lidar in China(41°N, 86°E). According to statistic data of wind field experiment in present-year, the low stratospheric zero wind Layer character over the region in summer and early autumn has been obtained, the zero wind layer generally exists on the height of from 18km to 23km, the wind speed is mostly less than 8m/s and the wind direction of zero wind layer understratum and superstratum is inverse.
