The potential impact of regional climate change on fire weather in the United States
The authors assessed potential changes in fire weather conditions across the contiguous U.S. based on the Haines Index to predict how fire activity and behavior may change due to climate change.
Across regional climate models (RCMs) and general circulation models (CGMs) the authors found that the number of days with a high Haines Index Value (? 5) increased across most of the contiguous U.S. during the summer season. The moisture component of the Haines Index (HI) was more influential in predicting future projected changes in conditions conducive to increased fire activity than the stability component of HI.
