According to the structure and function of jellyfish ears, bionics technologists designed a jellyfish ear storm predictor, which accurately simulated the organs of jellyfish that felt infrasound. This instrument is installed on the front deck of the ship. When it receives the infrasound wave of the storm, the horn that can rotate 360 will stop rotating by itself, and the direction it refers to is the direction of the storm. The reading on the indicator can show the intensity of the storm. This forecaster can forecast storms 15 hours in advance, which is of great significance to navigation and fishery safety.
