Annual and seasonal tornado trends in the contiguous United States and its regions

Study key findings & significance

  • The study provides evidence that tornado activity is increasing in the fall

Abstract

Previous studies provide evidence of possible changes to the climatology of tornadoes in the United States. These include a decrease in the number of tornado days per year, but an increase in the number of days per year with a large number of tornadoes; an increase in the mean number of tornadoes per tornado day; a spatial shift in tornado activity, generally towards the Southeast United States.

Increasingly Powerful Tornadoes in the United States

Study key findings & significance

  • There is a clear upward trend in tornado power over the past few decades that amounts to 5.5% per year controlling for time of day, time of year, natural variability, and the switch to a new damage rating scale. 
  • Part of the trend can be attributed to long-term changes in convective storm environments involving dynamic and thermodynamic variables and their interactions.

Abstract

Storm reports show an upward trend in the power of tornadoes.

Getting ahead of Flash Drought: From Early Warning to Early Action

Study key findings & significance

  • Though recent years have seen tremendous advances in our understanding of this extreme climate phenomenon, substantial work remains to fill scientific gaps and to address the drought early warning and mitigation needs of practitioners and policy-makers.

Abstract

Flash droughts, characterized by their unusually rapid intensification, have garnered increasing attention within the weather, climate, agriculture, and ecological communities in recent years due to their large environmental and socioeconomic impacts.
