Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. In addition, the protection scope of the present invention should not be limited only to the following specific structures or components or specific parameters.

[0035] The invention is based on the creative work of the eddy correlation method. The eddy correlation method [Anctilet.al., 1994] measures the covariance between the pulsation value of physical quantities (such as temperature, CO2, dissolved oxygen, etc.) and the vertical veloci...

Abstract

The present invention provides an ocean turbulence heat flux meter and its use method, which utilizes ocean detection fast temperature sensor and acoustic Doppler three-dimensional point velocity (ADV) instrument, through acoustic Doppler three-dimensional point velocity instrument attitude data The current velocity data is corrected, and the turbulent heat flux in the vertical direction of the ocean is measured based on the covariance of the vertical velocity fluctuation and temperature fluctuation, so as to realize the measurement of the turbulent heat flux below the sea surface. The invention utilizes the ADV and the fast temperature sensor to realize the direct measurement of the turbulent heat flux below the sea surface. The ADV self-contained battery and memory are used for self-contained measurement, and the turbulent heat flux meter designed in the present invention can be integrated and work on the submerged mark, and can perform long-term and all-weather measurement.

Description

Technical field [0001] The invention belongs to the technical field of ocean exploration, and specifically relates to an ocean turbulence heat flux meter and a use method thereof, which can measure the speed and temperature of the same moving particle at the same time and at the same point, and can measure the turbulent heat flux in the ocean. Background technique [0002] The mature and typical ocean observation technologies at home and abroad are marine submarine standard technologies, such as acoustic Doppler velocimetry (ADCP), thermohaline chains, etc. These observation techniques can basically meet the research needs of large and medium-scale marine dynamic processes, such as: Analysis of the coarse structure of ocean circulation, mesoscale vortex, thermohaline, etc. The observation of ocean turbulence microstructure is important for studying ocean vertical mixing (according to the potential density equation, the turbulent vortex diffusion coefficient required to maintain t...
