METHOD AND APPARATUS FOR ASSESSING IMPACT RANGE OF TYPHOON, TERMINAL DEVICE AND STORAGE MEDIUM

摘要

A method and apparatus for assessing the impact range of a typhoon, a terminal device and a storage medium. The method comprises: acquiring coastline positions, a typhoon landing position, the positions of a preset number of observation sites, and wind speeds at the observation sites that are in one-to-one correspondence with the observation sites (S101); establishing a coordinate system using the typhoon landing position as a coordinate origin (S102); dividing the coordinate system into several regions according to a preset division rule (S103); dividing the observation sites into several levels according to the wind speeds at the observation sites (S104); selecting the furthest main impacted site according to a preset selection rule, and using the furthest main impacted site as a fitting site of a corresponding level in a corresponding region (S105); and according to the position of the fitting site, fitting a boundary curve of the impact range of all levels of gales caused by typhoons (S106). According to the boundary curve, the impact range of a typhoon may be obtained, thereby providing a reference for typhoon prediction.
