This page hosts plots of integrated regional enstrophy (IRE) for the Northern Hemisphere (0^o to 70^o North).  Click this link to retrieve a short primer on what IRE is, and what the plots here mean.

The area integrated IRE is also shown for the latest run, as well as the recent history of IRE.  What drives these plots are the solutions from the 0000 UTC NAEFS ensemble members.
