Article Synopsis
- In spring 2018, infrasound sensor arrays in the southeastern US were used to analyze data during a storm front that caused multiple tornado touchdowns, with intensities ranging from EF-0 to EF-2.
- The sensors managed to accurately determine the locations of the tornadoes, detecting signals from over 100 km away, as well as earlier weaker signals from a convective storm cell that didn't produce tornadoes.
- The analysis revealed that the main infrasound signals from the tornadoes fell within a frequency range of 2 to 6 Hz, with atmospheric conditions impacting signal detection and requiring advanced signal processing methods to distinguish between multiple storm sources.
