A comparison of wind data detected by an automotive wind profiler and a meteorological tower reveals no significant differences between the two types of detection approaches for the landfall typhoon Kaitak. By using the data of automotive wind profiler radar, Typhoon KAITAK is studied, and the results show that around the time before and after the typhoon eye passing through, the wind speed exhibited an M shaped variation with the maximum wind speed in the strong wind zone around the wall of the typhoon eye, the maximum 10 min mean wind speeds being 357 and 354 m/s, and the minimum being 162 m/s.The automotive wind profile radar has strong detection capability, can effectively detect the wind shear and vertical airflow shear from ground to upper levels during the landfall typhoon and help improve typhoon forecasting service in the coastal area.
