A long-term climatology of North Atlantic polar lows
A dynamical downscaling of the 6-hourly 1948-2006 NCEP/NCAR re-analyses for the subarctic region of the North Atlantic has been used to derive a climatology of polar lows by means of a tracking algorithm based on the simulated bandpass filtered MSLP-fields. This climatology is consistent with the li...
