WeatherBrains 285: Full as a Tick and a Black Eye

WeatherBrains Episode 285 is now online (July 11, 2011). If you are crazy about weather, this is THE netcast audio program for you!

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.

Dr. Tatom, a registered professional engineer, has a broad engineering background with over 39 years experience in turbulent fluid dynamics. He has pioneered research in predicting turbulence properties in a flow field based on mean flow properties. In the field of turbulent fluid dynamics he has served as a consultant to a number of government agencies including: the Army Ballistic Missile Defense Systems Command; the National Aeronautics and Space Administration; the National Oceanic and Atmospheric Administration; the Tennessee Valley Authority; the U.S. Army Corps of Engineers; the U.S. Army Engineer Waterways Experiment Station; the Department of Energy; the Department of Labor; and the Occupational Safety and Health Administration. He has also served as a consultant to a number of private organizations including: the Gas Research Institute; Massachusetts Institute of Technology; Arthur D. Little, Inc.; Northrop Corporation; and General Dynamics Corporation. In 1983, he received NASA’s New Technology Award for his work in the simulation of atmospheric turbulence.

Other discussions in this weekly podcast include topics like:

  • Heat the BIG story across the country
  • One third of US under some sort of heat advisory
  • Severe weather across Great Lakes area
  • Tuesday, July 12, slight risk in Upper Midwest and New England
  • 32 at Truckee, CA, and 107 in Fort Smith, AR, and Stillwater, OK
  • and more!
  • Our Email Officer is almost as full of it as the mail bag. He brings us up-to-date on what listeners are writing about.

    From The Weather Center:

    WeatherBrains 101: Virtual stuff has been around with the computer, but meteorologists have had a virtual temperature for years. This week 101 looks at virtual temperature and how it is used in the field of weather.

    Listener SurveyListener Surveys: Okay, we continue to drive this topic into the ground, but we really do like to hear from you. Many thanks to everyone who has taken the time to fill out the Listener Survey. The survey takes just a minute or two to complete and provides us with an opportunity to learn where you are and hear your thoughts and comments on the show. Click here to take the survey.

    WeatherBrains 284: My Kids are Hurricanes

    WeatherBrains Episode 284 is now online (July 5, 2011). If you are crazy about weather, this is THE netcast audio program for you!

    Dr. Chris Landsea, SOO, NHC Miami, FLTonight’s Guest WeatherBrain, Dr. Chris Landsea, has been a research meteorologist with the Hurricane Research Division of the Atlantic Oceanographic and Meteorological Laboratory at NOAA. Now he is serving in the capacity of the Science and Operations Officer (SOO) at the National Hurricane Center. What does his job involve and what do hurricane forecasters do during the half of year when hurricanes don’t usually occur?

    NHC is once again the official name with TPC or Tropical Prediction Center having gone by the way. Few new products this hurricane season, but work is underway on some experimental products that will be available in the next couple of years. This includes extending the hurricane forecast to seven days.

    Other discussions in this weekly podcast include topics like:

  • Around the country, rip currents off New York
  • Slight risk in Central Plains tomorrow
  • 110 in Laughlin, Nevada
  • and more!
  • Our Email Officer continues to look for a replacement. But the mail bag still gets some attention, so Kevin summarizes your input.

    From The Weather Center:

    WeatherBrains 101: We talk alot about all the parameters that favor convection, but there are some conditions which inhibit convection. So this week WeatherBrains 101 delves into CIN or CINH.

    TWIWH: Bill Murray doesn’t look back at the week of July 5th! Instead he hosts a brief weather trivia quiz for the gang. So which dude on the show gets the most trivia questions right?
