Abstract
A method and a system for objective determination of typhoon intensity based on gradient wind balance are provided. The method includes the following steps: obtaining the first position of the center of the tropical cyclone at the current moment, the second position of the center of the tropical cyclone within the preset time from the current moment, and the minimum sea level pressure; determining a movement speed of the tropical cyclone based on the first position and the second position; obtaining wind field data within the fixed area to determine the scale of the tropical cyclone; obtaining atmospheric pressure field data to determine the average environmental pressure; and obtaining an intensity of the tropical cyclone based on the first position, the minimum sea level pressure, the average environmental pressure, the scale of the tropical cyclone, and the movement speed. It enhances the accuracy and objectivity of the typhoon intensity determination.
