A similar shift in the behavior of the jet stream has also contributed to the California drought and severe polar vortex winters in the Northeast over the past two years. An amplified jet-stream pattern has produced an unusual doldrum off the West Coast that’s persisted for most of the past 18 months. Daniel Swain, a Stanford University meteorologist, has called it the “Ridiculously Resilient Ridge” – weather patterns just aren’t supposed to last this long.

The “Ridiculously Resilient Ridge,” sometimes shortened to “Triple R” or “RRR,” is the nickname given to a persistent region of atmospheric high pressure that occurred over the far northeastern Pacific Ocean during 2013-2014. This anomalous atmospheric feature disrupted the North Pacific storm track during the winters of 2012-2013, 2013-2014, and 2014-2015, resulting in extremely dry and warm conditions in California and along much of the West Coast.[1] [2] The Ridge comprises the western half of atmospheric ridge-trough sequence associated with the highly amplified “North American dipole” pattern, which brought persistent anomalous cold and precipitation to the eastern half of North America[3] during 2014 in addition to record-breaking warmth and drought conditions in California
