DISCUSSION: As the research world wraps up neat global atmospheric events from throughout the course of 2017, one of the more interesting subjects to review is the importance of atmospheric blocking events. There is no debate that atmospheric blocking events have a profound impact on the larger-scale atmospheric flow regimes which evolve both on the synoptic-scale (i.e., spatial coverage on the order of thousands of kilometers) and the planetary scale (i.e., a spatial coverage on the order of hundreds of thousands of kilometers). Therefore, both direct and indirect impacts of atmospheric blocking events can often have incredibly far-ranging impacts on regional as well as continental weather events (and trends thereof). Attached above is a neat discussion (courtesy of Dr. Anthony Lupo of the University of Missouri) which helps to break down the duration of 2017 in the context of atmospheric blocking events and corresponding issues therein.
