Tornado generation characteristic detection device based on infrasonic wave

Technical Field

Background

Researchers have investigated the mechanism of tornado elimination and generation, and have found that a tornado-generating storm system produces low frequency sounds 1-3 hours before they occur, typically in the range of 0.5 to 20 hertz of "infrasonic waves" that the human ear cannot hear. Because infrasonic waves are not easily attenuated, they can be transmitted over hundreds of kilometers away and can be detected by instrumentation.

Modern meteorological science research shows that as ascending air flow enters stable air pockets, chain reaction is generated in the air pockets by the upward air flow, so that the change of a cloud layer in the atmosphere is caused, the dynamic structure of the cloud layer is changed, low-frequency swing ripples appear in the cloud layer, and accordingly gravity waves of the cloud are formed. For example, when a thunderstorm, a hail or a tornado is about to occur, the updraft changes in the vortex of the air, so that the fluid structure of the cloud changes, and when the change changes and accumulates continuously on the vertical gradient, the gravity wave of the cloud is finally generated. The gravitational waves of such clouds alternate at very low frequencies, substantially close to the frequency range of infrasound waves, causing infrasound waves in the atmosphere. One can measure this infrasonic wave by some special means, analyze and extract its characteristics, and further analyze and predict that a tornado may be imminent.

The infrasound waves are associated with the flow field characteristics, and the vibration close to the infrasound wave frequency can be transmitted for a long distance, so that when the tornado weather process is about to occur, the change can be detected at a long distance, meanwhile, the approximate direction of the tornado can be judged to a certain extent through a multipoint measurement positioning method, and the position and the distance of the tornado can be accurately judged by combining equipment such as a meteorological radar and the like, so that technical support is provided for early warning of the tornado.
