Abstract

The invention discloses a construction method of a three-dimensional ocean current real-time rapid analysis system based on satellite remote sensing; the method comprises the steps: assimilating on-site observation temperature and salinity profile data through a three-dimensional temperature and salinity field obtained through the vertical inversion of real-time satellite observation sea surface temperature (SST), sea surface salinity (SSS) and sea surface height anomaly (SSHa), and obtaining a three-dimensional temperature and salinity analysis field; and carrying out earth current conversion correction on the three-dimensional ocean current reanalysis background field, observing a sea surface wind field by using a satellite to calculate a wind ocean current, carrying out wind ocean current correction on the three-dimensional ocean current reanalysis background field, and constructing a three-dimensional ocean current real-time rapid analysis system based on a visual platform. The system has the characteristics of miniaturization and rapid analysis, and can be loaded on a ship to provide real-time marine environment condition guarantee for the ship, including sea surface height, three-dimensional ocean current, temperature, salinity, sound field and the like.

Description

technical field [0001] The present invention belongs to the technical field of ocean information, and specifically relates to providing a three-dimensional ocean current real-time analysis field as the goal, and building a three-dimensional ocean current real-time rapid analysis system (Quick Real-Time Ocean Current Analysis System) as a technical support, and through a visual interface to integrate the above analysis system An ocean current condition guarantee system that outputs results in real time for display. Background technique [0002] As an important element of the marine environment, ocean currents have been applied to many civil and military fields, such as navigation safety of ships at sea, search and rescue, oil spill disaster disposal, and weapon platforms. In terms of the navigation safety of civil ships, ship safety has always been a matter of great concern to the shipping industry. For a long time, the world's shipping countries have done a lot of work on s...
