North American Monsoon

The long version of the title is "An Investigation of North American Monsoon (NAM) Variability using Instrumental and Tree-Ring Data". A main objective of this study is improved understanding of the long-term variability of the North American Monsoon through use of partial-widthand stable isotope tree-ring data. The project includes both new and existing tree-ring collections.

• Document monsoon variability, decades to centuries
• Study covariation of NAM with winter precipitation variability
• Study links of NAM with ocean/atmosphere circulation
• Examine The consistency of downscaled general circulation model (GCM) simulations with paleoclimatic evidence of NAM variability
