  • Description:
    This atlas contains several statistics of monthly sea level pressure (SLP), mean 700 mb height, and 1000-700 mb thickness for each of the twelve months over the extratropical Northern Hemisphere for the 1950-1992 period. For each of the three fields, the statistics are presented in the following order: Following

    presentation of the mean and the departures from the zonal mean (i.e. eddy), the interannual standard deviation is shown. Next, the skew is displayed, followed by the month-to-month autocorrelation of the field. The autocorrelation identifies the locations and times of the year tending to have low-frequency persistence (or, on rare occasions, antipersistence)--a potentially important tool for long-range forecasters. Finally, the leading unrotated EOF is presented, including the spatial loading pattern and the accompanying amplitude time series for 1950-92. The compiling of the above statistics is intended to provide reference material for descriptive purposes and for forecast applications. A companion journal article (Barnston and Van den Dool 1993) highlights and extends some of the more interesting features of the maps for 700 mb height found in this atlas.
