Before the warning of marine storm, 8- 13HZ infrasound was generated by the friction between waves and air, which could not be heard by human ears, but could be heard by jellyfish's special auditory system. Scientists invented the jellyfish ear storm predictor by studying and imitating the auditory system of jellyfish. This instrument is installed on the front deck of the ship. When it receives the infrasound wave of the storm, it can automatically stop the horn rotating 360 degrees, 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.
