These indices are used to measure the NAO throughout the year, tracking the seasonal movements of the Icelandic low and Azores high. Positive values of the NAO index are typically associated with stronger-than-average westerlies over the middle latitudes, more intense weather systems over the North Atlantic and wetter/milder weather over western Europe. onGoing Phillips, Adam UCAR/NCAR - Climate and Global Dynamics Laboratory Associate Scientist asphilli@ucar.edu pointOfContact NETCDF Dataset theme Resource Type 2017-05-10 publication DataCite originator Earth Science > Climate Indicators > Atmospheric/ Ocean Indicators > Teleconnections > North Atlantic Oscillation > NAO GCMD 2017-07-18 revision GCMD originator Dash and its services comply with policies set by UCAR and NCAR. citation: NAO Index Data provided by the Climate Analysis Section, NCAR, Boulder, USA, Hurrell (2003).
