Abstract

Hurricanes, whether in the Gulf of Mexico or the open ocean, are known to produce infrasound in the microbarom band (around 0.2 Hz). Infrasound technology is an excellent choice for monitoring hurricanes because portable, sensitive, and relatively low-cost infrasound arrays can be deployed quickly in areas out of danger from storm winds and waves while still monitoring storm-related signals continuously. The National Center for Physical Acoustics is developing a Gulf Coast hurricane monitoring system involving permanent and portable infrasound arrays. This discussion will focus the results of infrasound studies of the 2008 hurricane season, along with background information on the history and theory of hurricane microbaroms. The latest results of theoretical calculations about the microbarom source and possible effects of storm winds on bearings will also be presented.
