Problems solved by technology
At present, the satellite remote sensing methods used for eddy observation can only observe the sea surface parameter information, and cannot 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 an ocean long-time eddy-following observation system and a design method. The vortex follower observation system includes sea surface floating balls, plastic-coated steel cables, upper damping blocks, lifting platforms, lower damping blocks, tensioning hammers, mooring cables, telescopic cables and water sails arranged in sequence from the ocean surface; the design method includes Collection of global vortex and background three-dimensional flow field data sets, vortex-current consistency analysis and law statistics, determination of sail deployment depth in vortex-following observation system, design of specific size of sail. The vortex-following observation system can synchronize with the vortex center with the greatest probability. Compared with conventional mobile devices such as Drifter, which is only driven by surface flow, and Argo, which does not follow the flow, it has the advantages of long vortex-following time and good observation effect; This application presents the methodology of long-time vortex tracking for on-site observation systems from the perspectives of big data statistics and theoretical analysis, which can provide a theoretical basis and basis for the design of all vortex tracking systems.
Description
technical field [0001] The invention relates to the technical field of ocean observation equipment, in particular to an ocean long-time eddy-following observation system and a design method. Background technique [0002] Oceanic eddies are ubiquitous in the ocean, appearing at all times, tens of thousands, and of different sizes. Their horizontal scales range from several kilometers to hundreds of kilometers, their vertical scales range from tens of meters to Day to several years, the daily propagation speed is on the order of kilometers, and it has the characteristics of horizontal local stirring, vertical biochemical flux, regional entrainment transport and three-dimensional cross-sectional structure. It is an ideal carrier for studying material cycle, energy cascade and circle-layer coupling. [0003] With the continuous deepening of eddy oceanographic research, the acquisition of multi-parameters of eddy profiles throughout the main life stages of eddies has become an ur...
