The evolution characteristics of the wind field at the lowlevel stratosphere are analyzed based on FNL reanalysis data from June to August 2017. After that, highresolution numerical simulations of the wind field at the lowlevel stratosphere are evaluated by sounding data at the Urumqi station. Results show that the temporal transition of the stratosphere zonal wind over the Xinjiang region varied with latitude. Meanwhile, the starting and ending time of the quasizero wind layer also varied with latitude. Starting time of the quasizero wind layer was earlier in the southern region than in the northern region. However, it was the opposite of the ending time. In summer, the quasizero wind layer existed between 70 hPa and 40 hPa over the Xinjiang region. Variation of the quasizero wind layer altitude presented a trend of declining first and then rising later. Results of the numerical simulation of the quasizero wind layer showed that the trends of the quasizero wind layer parameters over time displayed good agreement between simulations and soundings. The mean absolute error of the initial height of the quasizero wind layer was 467 m. The rootmeansquare error of wind speed at the initial height of the quasizero wind layer was 1.75 m/s.
