The propagation of infrasound from a vertically extended source is investigated. The source is allowed to have azimuthal and vertical variation. The radial extent of the source is assumed to be small compared to an acoustic wavelength. No such assump

The notion that tornadoes emit an infrasonic signal that can be detected from great distances; and thus be used to aid in the detection, monitoring, and potentially tracking of active tornadoes; has been discussed for decades. To test this notion, we

Infrasound propagation depends critically on the temperature and wind velocity profiles at the time of signal propagation. These vary wildly, showing at best qualitative systematic behavior. It follows that any predictions of signal detection capabil

On March 19, 2018, a storm front that produced at least eight confirmed tornadoes passed across northern Alabama. During that period, we had a network of infrasound arrays deployed throughout the region. Infrasonic signals were detected from each of

At a previous ASA meeting (Spring 2019), some results corresponding to application of maximum likelihood estimation with the complex Wishart distribution to direction-of-arrival of infrasound from tornadic storms were presented. In this presentation,

A confined, large explosion underground launches an infrasonic signal into the atmosphere generated by the heaving of the ground over the explosion. For example, the last three North Korean nuclear weapon tests produced infrasonic signals detected at

This study utilized seismograms from the U.S. Geological Survey seismological station near Ely, Minnesota, at which 39 delay-fired explosions at the U.S. Steel Minntac iron mine in Mountain Iron, Minnesota, were recorded. The waveforms were analyzed

The jet stream is an eastward flowing wind jet seen around 10 km with its largest magnitude in the winter months, lessening in the summer. Its direction, while predominantly easterly, can vary from northeast to southeast on a day-to-day basis. It can

Developed by the infrasound group at the National Center of Physical Acoustics, University of Mississippi, and a few collaborators, NCPAprop is an open source software package aiming at providing a comprehensive set of tested and validated numerical

Infrasound signals generated by hurricanes, appearing in the microbarom frequency band, often arrive along a bearing that does not point toward the eye of the hurricane where the winds are strongest. In general, the microbarom source region appears t
