• The North Atlantic Oscillation

  The term 'North Atlantic Oscillation' is used by meteorologists to refer to variations in the large-scale surface pressure gradient in the North Atlantic region.

  In the average state of the atmosphere, the North Atlantic surface pressure is relatively high in the subtropics at latitudes 20°N to 40°N ('the Azores High'), and lower further North at latitudes 50°N to 70°N (the 'Icelandic Low'). The North-South pressure difference determines the strength

• Climate monitoring of the land and atmosphere

  Global observations of surface and upper air temperature and humidity, surface pressure and precipitation are used to provide advice on global climate variability and change.

  stress. Key aims Monitor the climate near the land surface and in the upper air. Provide advice to Government, the media and others. Assist others in using and interpreting the information. Current activities Monitoring and developing analyses of: Surface air temperature and land surface temperature. Precipitation. Near-surface humidity. Upper tropospheric humidity. Near surface wind.
