The mean 500 hPa height field for (a) 23 Jan to 16 Feb 2014 and (b) 21 Feb to 2 Mar 2015, showing two blocking events that dominated their respective winter seasons in the Northern Hemisphere over the East Pacific. The time period encompasses the lifetime of the Pacific Region events, and contour intervals are at a 60 m interval. These were derived using reanalysis data found at http://www.esrl.noaa.gov/psd/data/reanalysis/reanalysis.shtml.
