Atmospheric Forcing Index (AFI) correct URL: http://www.pac.dfo-mpo.gc.ca/science/species-especes/climatology-ie/cori-irco/indices/afi.txt In order to make use of this index, you are requested to cite the original manuscript (below). For more information about this index, please see the original manuscript, or contact Dr. Jackie King (KingJac@pac.dfo-mpo.gc.ca). This index has been updated from the paper below, and due to the nature of the multivariate statistics used to generate the annual values, the time series values may have changed slightly. The Atmospheric Forcing Index utilizes standardized scores of the first component from a principal components analysis on the Aleutian Low Pressure Index, Pacific Interdecadal Oscillation Index and the northwesterly atmospheric circulation anomalies for the North Pacific (December through March). Positive values represent intense Aleutian lows, above average frequency of westerly and southwesterly winds, cooling of sea surface temperatures in the central North Pacific, and warming within North American coastal waters.
