Based on data from the Qizhou Archipelago Weather Station and Haikou S-band weather radar, along with 1-minute observations from automatic weather stations, this study systematically analyzed the variation characteristics of Atmospheric pressure and wind speed during the passage of the super typhoon "Yagi" in 2024. The findings indicate: the observed minimum Atmospheric pressure and peak gust times exhibit significant synchronization with weather radar data; the Atmospheric pressure trends from two sets of weather stations show high consistency, with a correlation coefficient as high as 0.9998; Atmospheric pressure undergoes dramatic changes as the typhoon eye wall passes, with substantial positive and negative minute pressure variations, reaching a maximum negative pressure change of -4.2 hPa and a maximum positive pressure change of 4.0 hPa. Analysis of wind speed data at different time intervals reveals considerable fluctuations in peak wind speeds, with the ratio of 1-minute peak wind speed to 2-minute average wind speed fluctuating between 1.00 and 1.47, averaging 1.15; the ratio of 2-minute average wind speed to 10-minute average wind speed varies between 0.82 and 1.28, averaging 1.01. During the typhoon, the gust factor ranged between 1.2 and 1.5, with higher values observed in the early stages of typhoon impact. As the typhoon center approached the observation station, the gust factor gradually stabilized.
