This page is about VWP hodographs, which are graphical representations of the wind speed and direction at different altitudes. The page allows the user to select a radar station, a storm motion, and a boundary orientation to generate a hodograph based on VAD (Velocity Azimuth Display) data. The page also provides information on various parameters related to the hodograph, such as bulk wind difference, storm-relative helicity, and critical angle. The page is part of Tim Supinie’s personal website, which also contains other side projects related to weather, almanacs, recipes, and wedding pictures.
