Group: Summary

   This data set comprises a 50-year record of daily extratropical cyclone 
   statistics computed for the Northern Hemisphere. Cyclone locations and 
   characteristics were obtained by applying the updated Serreze (1997) algorithm 
   to daily Sea Level Pressure (SLP) data at six-hour intervals (Serreze and 
   Barrett 2008). The SLP source data are part of the National Centers for 
   Environmental Prediction (NCEP) and National Center for Atmospheric Research 
   (NCAR) Reanalysis data set, an assimilation of various atmospheric data 
   collected by a wide variety of sensors within a global weather model. The 
   parameters included in this data set are the position and central pressure of 
   each cyclone, the distance the center of the cyclone traveled, whether the 
   observation represents a cyclogenesis or cyclolysis event, and the local 
   Laplacian of SLP and Sea Level Pressure Tendency (SLPT) at each cyclone 
   center. The total volume of this data set is approximately 150 megabytes. Data 
   are provided in tab-delimited ASCII text format and are available via FTP.
