The invention discloses an expendable air-sea flux buoy which comprises a micro weather station, a temperature and moisture measuring instrument, a supporting rod, an instrument control cabin, a core pulling floating ball and a counterweight. A cabin body of the instrument control cabin is arranged in the core pulling floating ball. The micro weather station and the temperature and moisture measuring instrument are arranged on the supporting rod above the instrument control cabin. The bottom end of the instrument control cabin is connected with the counterweight through a connecting rod.

The upper end face of the instrument control cabin is provided with a satellite antenna. The expendable air-sea flux buoy floats along with flow, collects the meteorological parameters at an air-sea interface and the hydrologic parameters of the sea surface, calculates the air-sea flux and provides a novel observation method for observation and research of multi-scale air-sea interaction. The expendable air-sea flux buoy and an existing observation method are used in a combined mode, the observation capacity of the air-sea flux in the global ocean range can be greatly improved, and important datum support is provided for ocean disaster prevention and reduction, ocean environment guarantee, global climate change research and the like.

Description

technical field [0001] The invention relates to an ocean mobile measurement platform, in particular to an abandoned buoy for measuring the flux of the sea-air interface. Background technique [0002] Air-sea flux refers to the amount of material and energy exchange between the ocean and the atmosphere per unit time and unit area. important parameters. The air-sea energy flux includes momentum flux, sensible heat flux and latent heat flux. The study of heat flux at the air-sea interface not only helps us to understand the process of air-sea interaction more clearly and provides a theoretical basis for the study of global change, but also can provide more accurate boundary conditions for the air-sea interface for numerical prediction models. This is very important for understanding the physical mechanism of air-sea interaction, global climate change and accurate forecast of typhoon (hurricane) wind. [0003] At present, the air-sea flux observation methods mainly include th...

Problems solved by technology

Moored air-sea flux buoys obtain meteorological parameters at a height of 10m through inversion of meteorological parameters at about 4m. However, due to unfavorable factors such as high cost and inconvenient maintenance, they are rarely used globally and have insufficient spatial resolution.

Ship-based observations are basically carried out around fixed routes, and are generally carried out when the sea conditions are good, so it is difficult to carry out air-sea flux observations under various air-sea dynamic conditions

Satellite observation is actually the calculation of air-sea interface heat flux through meteorological and hydrological parameters directly or inverted by satellite remote sensing, but limited by satellite orbit interval and orbit repetition time, the time and space resolution of satellite observation data is low, and the error larger

Generally speaking, the existing air-sea flux observation technology equipment is relatively complicated, the cost is high and it is difficult to maintain. The observation range is limited in the complex marine environment and it is difficult to meet the high temporal and spatial resolution under multi-scale and various sea-atmosphere processes. rate of air-sea flux observation requirements
