Data:  NCEP reanalysis monthly mean sea level pressure on a 2.5 x 2.5 deg. lat/lon grid.
Base Period:  1961-1990
Data Source:  NCEP

Description:
These plots indicate the observed field and anomaly in sea level pressure. The standardized anomaly plots are constructed by dividing by the standard deviation for the base period 1961-1990.  NCEP is an acronym for the National Centers for Environmental Prediction, US.
