Ocean environment data generation method and system based on ROMS

The invention relates to the technical field of data simulation, in particular to an ROMS-based marine environment data generation method and system, and the method comprises the steps: constructing an initial operation model, and forming an ROMS mode; the initial operation model comprises a geographical environment model, an initial field model, a forced field model and a boundary condition model; performing time-space splitting on the test task according to the requirement of the test task on the marine environment; automatically calling a running script, controlling the ROMS mode to run, and generating marine environment data required by a corresponding test task; and displaying the operation state of the ROMS mode and the generation progress of the marine environment data in real time. Aiming at the requirement of a virtual equipment test for ocean data, on the basis of an open-source regional ocean mode ROMS, ocean data resources with specified space-time range and space-time resolution including a flow
