    Abstract

    A mobile Rayleigh Doppler lidar system based on molecular double-edge technique, it was applied to Shanxi Xinzhou (38.42°N 112.72°E) and Gansu Jiuquan (39.74°N 98.49°E) continuous observations of stratospheric wind from 2014 to 2016. The wind data analysis results shows that: During the observation period, within the range of 18-25 km, the atmospheric structure of quasi-zero wind layer appeared in Jiuquan spring, autumn season and Xinzhou winter, and there was a phenomenon of floating up and down. The observed results are obviously different from the quasi-zero wind layer observed in Urumqi (42.1 °N 87.1 °E) in summer 2011. The analysis is that the stratospheric easterly circulation in the mid-latitude region of the mid-latitude region has not been stable and the zero-wind line is floating up and down due to the short-season transition period in May and October, and the stratospheric quasi-zero wind layer in the region of January 2015 may be related to the explosive temperature rise of the stratosphere.
