A storm surge early warning method for coastal high-risk areas

By using dynamically nested encrypted grids and fully coupled wave-current calculations, the problem of insufficient wave-current coupling calculation accuracy in complex nearshore terrain areas of traditional storm surge warning systems has been solved, enabling refined identification and high-precision warning of complex terrain.

Abstract

The present application provides a kind of storm surge early warning method for coastal high-risk area, belong to storm surge early warning technical field, the present application is by obtaining the meteorological field data and ocean hydrographic data of target sea area to establish basic grid system, based on burr constraint vector to grid is dynamically nested encryption generation nearshore high-resolution subgrid, meteorological field data is input scale separation parameterization model to generate multi-scale driving field, on encryption subgrid, establish wave flow complete coupling equation group, through iteration, realize the dynamic consistency calculation of wave field and flow field, according to scale sensitivity index matrix, adaptively adjust grid resolution, finally extract nearshore water level increase characteristics to generate sub-regional warning level, solve the technical problem of insufficient wave flow coupling calculation precision of storm surge early warning system in nearshore complex terrain area.
