WeatherBrains 285: Full as a Tick and a Black Eye

Our guest for the show tonight is Dr. Frank Tatom, head of Engineering Analysis, Inc., Huntsville, AL. Dr. Tatom shares a concern about the false alarm rate. From his personal research, he believes there is strong scientific evidence that tornadoes in contact with the ground produce a seismic signal which is detectable at distances of 10 to 20 miles. With a network of seismic sensors spaced roughly 15 miles apart, confirmation of a tornado touchdown could be accomplished when used in conjunction with NWS NEXRAD radar.
