Robust increases in severe thunderstorm environments in response to greenhouse forcing

  • Uses an ensemble of global climate model experiments to probe the severe thunderstorm response
  • Finds that this ensemble exhibits robust increases in the occurrence of severe thunderstorm environments over the eastern United States
  • Finds, in addition, that the simulated changes in the atmospheric environment indicate an increase in the number of days supportive of the spectrum of convective hazards, with the suggestion of a possible increase in the number of days supportive of tornadic storms
  • Concludes that such increases imply increasing risk of thunderstorm-related damage if global warming continues
