METHOD FOR CACULATING RADIUS OF TYPHOON INFLUENCE

摘要

PURPOSE: A calculating method of a radius of typhoon is provided to assume the extent of a damage by a typhoon and to reduce the damages by typhoon influence in advance. CONSTITUTION: A calculating method of the influence radius of typhoon comprises: a step of calculating the location of a long diameter direction(S110); a step of selecting a random location(S120); a step of respectively calculating the location of the long diameter direction and a distance between the central location of the typhoon and the selected random location(S130); a step of calculating an angle between a line from the location of the long diameter direction to the central location of the typhoon, and a line from the central location of the typhoon and the selected random location(S140); a step of determining the influenece radius of a typhoon(S150); and a step of determining whether the location is under the influence radius of the typhoon(S160).
