Abstract The non-stationarity and vertical coupling of the boundary-layer wind field during typhoon passage are key concerns for wind engineering and disaster prevention. Using hourly ERA5 reanalysis data, this study investigates the evolution of the 10 and 100 m wind fields throughout Typhoon Lekima (2019) by combining BFAST breakpoint detection, Hurst exponent analysis, correlation analysis, and segmented linear fitting, together with near-surface temperature, 850 hPa temperature, and mean sea level pressure fields. BFAST detected a structural breakpoint at all 525 grid cells, with breakpoint timing progressing along the storm track (median 26 h at 10 m… More >
