Proposal of Pressure Calculation Method for a Model of Potential Intensity

Abstract A method for calculating the minimum central pressure in a model of potential intensity of tropical cyclones determined from the Willoughby wind profile, which provides a physically direct relationship between the central minimum pressure and the maximum wind speed in the surface is proposed. It was observed that the model for the most intense hurricanes of the Atlantic basin maintained an uncertainty of a maximum value of 6 hPa. Values of pressure very close to the reality were noticed. It was checked the ability to simulate the minimum central pressure and the maximum surface wind speed for less intense hurricanes within very close range to the actual values.
