The North Atlantic Oscillation 1959-1998 : a data study
The North Atlantic Oscillation (NAO) refers to a low-frequency mode of atmospheric variability with two centres of action in the pressure field. The present study examines various atmospheric fields associated with the NAO. The NCEP/NCAR reanalysis data set from 1958--1998 is used. We find that the...
