    WNDCOM is a mathematical model for estimating surface winds in mountainous terrain. By following the procedures described, the sheltering and diverting effect of terrain, the individual components of the windflow, and the surface wind in remote mountainous areas can be estimated. Components include the contribution from the synoptic scale pressure gradient, the sea breeze, the slope wind, and the valley wind. For each component, a brief description, the data and information needed for estimation, and step-by-step procedures are provided.
