General circulation models and high resolution regional climate models (RCMs) are being used to simulate climate of the recent past and to project future climate change across the northeastern US. We are interested in the timing of changes regionally, as compared to the changes occcurring nationally and globally, and the patterns of key parameters that are of relevance to natural systems (frost occcurrence, snow cover, drought, fire hazard conditions, etc). We are also assessing the consistency of climate models in simulating recent climate changes, in order to improve confidence in future scenarios.
