North Pacific Gyre Oscillation (NPGO)
A pattern of variability of NE Pacific Ocean sea surface heights.
Correlation of the January Sea Surface Height (SSH) from the NCEP/GODAS Dataset with the NPGO index.
Description
-
The North Pacific Gyre Oscillation (NPGO) is a climate pattern that emerges as the 2nd dominant mode of sea surface height variability (2nd EOF SSH) in the Northeast Pacific. The NPGO is significantly correlated with previously unexplained fluctuations of salinity, nutrients and chlorophyll-a measured in long-term observations in the California Current (CalCOFI) and Gulf of Alaska (Line P). See the NGPO webpage at Georgia Tech for more infomation.
