Summary We propose to investigate possible changes in extreme precipitation and temperature events in the Arctic using observational records and multi-model output from regional and global climate programs. Our two guiding hypotheses are:
1. A robust understanding, detection and attrition of changes in extreme temperature or precipitation occurs through analysis that combines extreme temperature or precipitation events with the physical processes supporting them.
2. Analysis of the atmospheric state producing temperature or precipitation extremes offers better potential for subcontinental detection and attribution compared to local precipitation or temperature analysis alone because it combines the extremes with fields such as large-scale pressure, circulation and temperature that tend to be more robustly simulated that the extremes themselves and that describe processes governing the extremes.
