This figure appears in chapter 5 of the Climate Science Special Report: The Fourth National Climate Assessment: Volume I report.

Cold season relationship between climate indices and U.S. precipitation and temperature anomalies determined from U.S. climate division data,3d9da69e-293a-4492-a418-682590c676c7 for the years 1901–2014. November–March mean U.S. precipitation anomalies correlated with (a) the Pacific Decadal Oscillation (PDO) index, (b) the El Niño–Southern Oscillation (ENSO) index, and (c) the North Pacific Index (NPI). November–March U.S. temperature anomalies correlated with (d) the PDO index, (e) the ENSO index, and (f) the NPI. United States temperature and precipitation related to the Pacific Decadal Oscillation are very similar to (and indeed may be caused by) variations associated with ENSO and the Aleutian low strength (North Pacific Index).
