Problems solved by technology
At present, the satellite remote sensing means used for eddy observation can only observe the sea surface parameter information, and cannot yet realize the three-dimensional observation of the profile; There are certain deficiencies or limitations in the acquisition of the total number of profiles
In addition, the depth position of the observation system in the vortex is usually placed based on practical experience, and there is no exact methodology for reference, and the observation effect is not ideal

The invention relates to the technical field of ocean observation equipment, in particular to a marine long-time vortex-following observation system and a design method. The vortex-following observation system comprises a sea surface floating ball, a plastic-coated steel cable, an upper damping block, a lifting platform, a lower damping block, a tensioning hammer, a mooring cable, a telescopic cable and a water sail which are sequentially arranged from the sea surface to the bottom. The design method comprises the steps of collection of a global vortex and background three-dimensional flow field data set, vortex-flow consistency analysis and law statistics, determination of the deployment depth of the water sail in the vortex-following observation system and design of the specific size of the water sail. The vortex-following observation system can be synchronized with the vortex center with the maximum probability, and compared with Drifter only driven by surface flow and Argo and other conventional mobile devices without flow following performance, the vortex-following observation system has the advantages of being long in vortex-following time and good in observation effect. In addition, a methodology for realizing long-time vortex following of the field observation system is given from the angles of big data statistics, theoretical analysis and the like, and a theoretical basis and basis can be provided for the design of all vortex-following observation systems.
Description
Technical field [0001] The present invention relates to the technical field of marine observation equipment, and in particular, a long-term vortex observation system and design method for ocean use. Background technique [0002] The ocean vortex is everywhere in the ocean, no time, tens of thousands, size, horizontal scale from a few kilometers to a few kilometers, vertical scale from several tens of meters to a few hundred meters, time scale from a few In a few years, the speed of transmission is in kilometers, and has a horizontally local stirring, vertical biochemical flux, regional, and three-dimensional sectional structural features, is an ideal vector coupling of a substance cycle, energy cascading and circle layer. [0003] With the continuous deepening of vortex oceanography, multi-parameters throughout the main life stage of vortex becomes an urgent need for the development of vortex intersection. The satellite remote sensing means currently used for vortex observations ...
