Short summary
This study uses the WRF–CALMET model to study the influence of topography near Zhongchuan Airport on low-level wind shear. The simulation accuracy of CALMET is higher than that of WRF. Terrain sensitivity experiments highlighted CALMET's ability to respond to terrain changes during periods of high wind speeds. This study verified the effectiveness of CALMET in simulating low-altitude wind shear, highlighting its excellent ability to capture terrain effects and mitigate aviation safety issues.
