(Bottom left) Reconstruction of El Niño precipitation anomalies during December and January. (Bottom right) The average precipitation anomaly from December 2015 and January 2016. The 250mb winds are from the NCEP/NCAR Reanalysis. Precipitation is from the CPC Unified precipitation (Chen et al., 2008). The dataset is station based, so areas with sparse observing networks will not show anomalies or will show a roughly concentric anomaly around a station (this is the case over large regions of Canada). Anomalies are calculated by subtracting the 1981-2010 monthly averages. Image by Michelle L’Heureux and NOAA Climate.gov.
