METHOD FOR ISSUING NOTICE OF WARNING FOR RIP CURRENTS

摘要

PURPOSE: A method for generating rip currents warning is provided to generate proper warning by accurately reflecting a field which is changed in real time. CONSTITUTION: Simulation is performed about state generating rip currents in a target area. Flow velocity of an ocean current is calculated(S1). Degree generating the rip currents is quantized as an index in the target area according to a virtual marine condition scenario. A rip current generating index is calculated(S2). The rip current generating index is calculated with changing the virtual marine condition scenario(S3). Whether or not rip current warning generation is determined(S4).
