Figure 3: DJF California precipitation versus SST trend correlation map.
From: El Niño-like teleconnection increases California precipitation in response to warming
21st century trend correlation between California (CA) precipitation and SST across individual realizations for the CMIP version 5 (CMIP5) model subset that yields a detrended DJF Niño 3.4 SST versus CA precipitation correlation of (a) at least 0.30 (CMIP5 HIGH-r), (b) <0.20 (CMIP5 LOW-r) and (c) the CESM LENS. (d) The observed 1948/49 to 2014/15 DJF correlation based on interannual variations, including precipitation from NOAA Precipitation Reconstruction and SSTs from the NCEP/NCAR Reanalysis. Symbols represent significance at the 90% (diamond), 95% (X) or 99% (+) confidence level, accounting for autocorrelation.
