Mystery sounds from storms could help predict tornadoes – The Guardian

Storms produce noises prior to tornadoes form, but the signals at less than 20Hz are below the limit for human hearing., pressure relaxation, and latent heat impacts,” stated Dr Brian Elbing, of Oklahoma State University, who is part of the team behind the research study. The subject has seen renewed interest in recent years, with Elbing saying it might prove especially helpful for uneven locations such as Dixie Alley, which stretches from Texas to North Carolina.”There is evidence that the amount of lead time prior to the twister is dependent on how large the tornado is,” said Elbing, including that low-frequency sounds have been detected up to two hours before a twister forms.

The topic has seen renewed interest in current years, with Elbing stating it could prove particularly useful for sloping locations such as Dixie Alley, which extends from Texas to North Carolina.”There is evidence that the quantity of lead time before the twister is dependent on how big the twister is,” said Elbing, adding that low-frequency noises have actually been identified up to two hours prior to a tornado forms.
