Some Considerations for the Use of High-Resolution Mobile Radar Data in Tornado Intensity Determination

  title={Some Considerations for the Use of High-Resolution Mobile Radar Data in Tornado Intensity Determination},
  author={Jeffrey Snyder and Howard Bluestein},
  journal={Weather and Forecasting},
AbstractThe increasing number of mobile Doppler radars used in field campaigns across the central United States has led to an increasing number of high-resolution radar datasets of strong tornadoes. There are more than a few instances in which the radar-measured radial velocities substantially exceed the estimated wind speeds associated with the enhanced Fujita (EF) scale rating assigned to a particular tornado. It is imperative, however, to understand what the radar data represent if one wants…
