Abstract

The present invention provides a calculation method, device and electronic equipment for the frequency of internal waves in the ocean. The method includes: acquiring satellite remote sensing data and sea surface roughness data of the target sea area within the target time period, and obtaining the satellite remote sensing data corresponding to The number of working days that the remote sensing satellite covers the target sea area within the target time period; determine the initial value of the occurrence frequency of ocean internal waves according to the satellite remote sensing data; correct the initial value according to the sea surface roughness data and the number of working days to obtain the occurrence frequency correction value. In the embodiment of the present invention, for the occurrence frequency of ocean internal waves determined by satellite remote sensing data, it is corrected according to the number of working days of the remote sensing satellite and the sea surface roughness data, which can relieve the sea surface roughness when the sea surface roughness is within a certain range. Part of the strips other than ocean internal waves are formed on the remote sensing image, which leads to inaccurate statistics of the occurrence times of ocean internal waves, thus improving the accuracy of calculating the frequency of ocean internal waves.

Description

technical field [0001] The invention relates to the technical field of marine information, in particular to a calculation method, device and electronic equipment for the frequency of occurrence of internal waves in the ocean. Background technique [0002] Oceanic internal wave is an ocean phenomenon, which transmits the energy from the upper layer of the ocean to the deep layer, and brings the colder seawater and nutrients from the deep layer to the warmer shallow layer, which plays a role in the mass, momentum, and energy transport in the ocean. important role. The generation of internal waves in the ocean has a great impact on the development of the industrial and agricultural economy and the military. With the development of society and the improvement of science, more and more attention has been paid to the development, utilization and survey of the ocean. [0003] Satellite optical remote sensing technology has always been an important technical means to explore the l...
