Global Decadal Hydroclimate Variability, Predictability and Change: A Data-Enriched Modeling Study (GloDecH)

Lead PI: Dr. Richard Seager

Unit Affiliation: Ocean and Climate Physics, Lamont-Doherty Earth Observatory (LDEO)

August 2010 - July 2015
Project Type: Research

DESCRIPTION: The team will study the mechanisms linking continental, subcontinental, and region hydroclimates to the global climate system to develop the physical foundation for experimental predictions of hydroclimate change. Coral samples will be used to reconstruct sea surface temperature which will be combined with tree ring samples to construct historic hydroclimates. These records will be combined with IPCC predictions to predict short-term hydroclimate.

OUTCOMES: Showed that Colorado River head waters will decline by 10%; demonstrated the importance of SST to hydroclimate in most of the Americas, but also that high amplitude, internal variability of atmospheric circulation; explained droughts in North America, the 2011 drought in Texas and Mexico, and much more. 31 papers submitted, 4 manuscripts in preparation, 25 presentations given in year 3, 5 workshops organized, 12 outreach programs completed.
