Weather and Climate Data Analysis: Monthly Temperature Anomalies for Central Pacific Modoki and East Pacific El Niño Years

The goal was to compare monthly temperature averages in the continental U.S. to years that included a Modoki El Niño when above average sea surface temperatures were in the Central Pacific Ocean.  The years chosen were pulled from a publication in the Journal of the Meteorological Society of Japan, Differences in Teleconnection over the North Pacific and Rainfall Shift over the USA Associated with Two Types of El Niño during Boreal Autumn (Zhang et al. 2012).  East Pacific El Niño maps were also generated for comparisons.


The following graphics show U.S. monthly temperature anomalies (values relative to normal) compared to composite years that had El Niño conditions.  Meteorologists have continued to reiterate that a Modoki El Niño could develop later this year (2014), though the most recent trends have been toward a weaker event.
