Heat Waves and Cold Spells of the 21st Century

William Putman, Mike Bosilovich, and Steven Pawson

This simulation, produced by the Goddard Earth Observing System Model Version 5 (GEOS-5) at 12.5-km resolution, shows surface temperature anomalies for the period January 1, 2000 to December 31, 2013. These anomalies are 7-day running means of local differences from the MERRA-2 reanalysis daily climatology and align with observed extremes throughout the record of observation. The increased resolution of the simulation provides additional detail on the regional impacts of these extremes.

This simulation highlights prolonged heat-waves and cold-spells across the globe throughout the 21st century. These include, among others: the severe European heat-waves of 2003, 2006 and 2007; the North American heat wave of 2006; and the extreme heat wave throughout the northern hemisphere in 2010.
