Firstly, the paper describes the system model of HWM93, develops a display system of wind field in the middle atmosphere based on HWM93. The analysis and comparison was implemented between the wind field data calculated by HWM93 model, wind data observed by L-band sounding system (0-30 km) and TIDI onboard TIMED satellite (70-110 km). In the height of 0-30 km, there is a good consistency in mean zonal wind between HWM93 and L-band sounding system in December, January and February, while great difference exists below 20 km in June, July and August and good agreement is showed above 20 km in these months. The meridional wind below 30 km computed by HWM93 model is not accurate enough to reflect the actual meridional wind. In the height of 70-110 km, the mean zonal wind from HWM93 and TIDI is in good agreement above 80 km, while the mean meridional wind it has small relative difference above 80 km. The results indicate that the wind above 20 km from HWM93 model could be provided as reference and foundation for the wind information in the middle atmosphere for the regions with relatively lacking wind-measurement stations.
