★ [MTT41-06] Severe weather phenomenon detected by pressure sensors -thunderstorm-
Keywords:Infrasound, severe weather phenomenon, XRAIN, thunderstorm
Infrasound signal is generated by rapid compress atmospheric such as thunder and vortex rotation by wind. Infrasound array system can detect arrival direction, but it is difficult to estimate the distance from source to observation point only one Infrasound array system.
Many meteorological disturbance in combination with thunder occurred on the Kanto region in the summer of 2014. In order to evaluate meteorological disturbance more accurately, we set up new Infrasound array system in Saitama Prefecture in addition to the existing in Chiba Prefecture.
The back azimuth of signals at two Infrasound array system intersect, and the place was high precipitation intensity on XRAIN image.
