Formal Title: North American Climate in CMIP5 Experiments
This special collection of Journal of Climate is devoted to North American climate and related processes in Coupled Model Intercomparison Project 5 (CMIP5) experiments, and organized by the CMIP5 Task Force of the NOAA Modeling, Analysis, Predictions, and Projections Program. The core of the special collection consists of three comprehensive articles that summarize CMIP5 models’ ability to represent 20th century North American 1) continental and regional climate and 2) intraseasonal to decadal variability, and provide 3) model projections of North American climate for the end of the 21st century. Papers providing more detailed examination of specific aspects of North American climate accompany these three core studies. The specialized contributions not only include direct examination of North American climate, but also global climate phenomena relevant to North American climate. Topics covered by the special collection include regional precipitation and temperature, snowpack, the hydrologic cycle, growing season length, land-atmosphere interactions, extreme events including drought, Arctic sea ice, the North American monsoon, the Great Plains low-level jet, the “warming hole”, extratropical and tropical cyclones, intraseasonal variability, ENSO and its teleconnections, Pacific decadal variability, and the Atlantic warm pool. How CMIP5 results compare to those from CMIP3 are discussed. Model bias and how it affects interpretation of future projections is also explored.
