Supplementary material to "Study on the influence of topography on wind shear-numerical simulation based on WRF-CALMET"

Supplement 1.Calmet model introductionCALMET employs a two-step method to compute the wind field.In the first step, the initial guessed wind field is adjusted based on the kinematic impacts of terrain, blocking effects, and slope flow.The second step involves incorporating observational data into the wind field derived from step 1 using an objective analysis procedure.CALMET, as a three-dimensional microscale meteorological diagnostic model, incorporates the kinematic impacts of terrain on vertical velocity and horizontal wind components, the influence of terrain on wind field dynamics, and the thermodynamic blocking effects of terrain on wind field dynamics.The simulation of near-surface winds in the model is highly sensitive to the localized effects caused by the uneven nature of terrain and the Earth's surface.
