Forcing of Eastern Boundary Current Regions

PI: Noah S. Diffenbaugh
Institution: Purdue University
The subject of the analyses will be the seasonality and annual- to decadal-scale variability of large-scale forcing of eastern boundary current (EBC) regions. EBCs support highly productive marine ecosystems, as well as large agricultural areas. They are forced by both regional- and large-scale processes, including annual to decadal modes such as ENSO and PDO. The objectives of the analysis will be (1) to test the ability of the participating coupled GCMs to reproduce observed records of 20th century seasonality and variability of large-scale EBC forcing and (2) to evaluate those large-scale processes in the SRES A1B and B2 scenarios. The analyses will use output from the 20th century simulation (from either run 1 or run 6 on the WGCM run list) and the SRES A1B and B1 simulations (from run 2 and run 3 on the WGCM run list). Model data will come from the time-independent 2-d land surface and ocean data, monthly-mean 1-d ocean data, monthly-mean 2-d atmosphere, land surface, ocean and sea ice data, and monthly-mean 3-d atmosphere and ocean data (Tables A1a, A1b, A1c, O1a, O1b, O1c, O1d, O1e). While it is of course impossible to know all of the variables of potential interest prior to conducting the analyses, variables of known interest include: psl, pr, tas, mrso, uas, vas, clt (Table A1a), orog, sftlf (Table A1b), cl, ta, ua, va, hus, wap, zg, hur (Table A1c), tos (Table O1c), zobt (Table O1d), so, uo, vo, and wo (Table O1e). The minimum required variables are pr, ts, ta, ua, va, zg, and wo.
