In this paper， a typical transverse dunefield in the western parts of the Korqin Sandy Land was selected as study area， and a series of automatic meteorological stations were installed at the summit， the interdune corridor and the lower stoss to observe the wind conditions inside the mobile transverse dunefield for 16 consecutive months in the field. To effectively illustrate whether the nearby weather stations can truly reflect the actual wind characteristics inside the dunefield， the hourly average data of wind regimes for the same period were obtained from the Wengniut Banner National Meteorological Station. The results show that： （1） the dominant wind direction in the corridor during the year is SW， which is basically the same as the stoss but with higher frequency， and the wind direction is deflected to the left at a large angle compared with the summit （WNW） and Wengniut Banner （NW）； （2） the average wind speed in the corridor during the year is 3.28 m?s^-1， and the average wind speed in spring can reach 4.74 m?s^-1， and the instantaneous wind speed is greater than the local threshold speed； the corridor has stronger wind and sand activities at this time， which plays an important role in shaping the complete form of the corridor and forming a stable spatial pattern of dunefield； （3） the sand transport potential of corridor is 37.94 VU， which is lower than the summit by 94.54% and higher by 86.99% than Wengniut Banner， thus it can be seen that the wind data measured by the nearby meteorological station cannot truly reflect the actual situation of wind and sand activities inside the dunefield； （4） in order to estimate the real situation of sand transport inside the dunefield more accurately， it is recommended to deploy at least one set of automatic meteorological station at the summit and another at the corridor for joint observations. This study has important theoretical and technical support value for revealing the overall wind condition change pattern of dunefield and sand disaster prevention and control.
