  • Predicting tropical cyclone destructive potential by integrated kinetic energy according to the Powell/Reinhold scale
    Patent number: 7970543
    Abstract: A method of predicting the destructive capacity of a tropical cyclone based on a new Wind Destructive Potential (WDP) and Storm Surge Destructive Potential (SDP) scales which provide a manner to rate the severity of hurricanes and typhoons, based on information provided in operational forecast and warning products, experimental wind field products, or gridded numerical weather prediction model outputs. These new scales are formulated to be consistent with the physical mechanism through which tropical cyclones impact coastal communities through wind, storm surges and wave damage.
