| Domain | Atmospheric | Description | Surface pressure is a fundamental meteorological variable for which observations are required for initialising forecasts and for use in reanalysis systems. It is an indicator of circulation patterns: differences between surface pressures at pairs of stations provide traditional indices of the North Atlantic and Southern Oscillations. Other indices are based on zonal-means or principal-component analyses of gridded fields. Surface pressure also provides information on the intensity of weather systems, including tropical cyclones. It has an impact on sea level. [GCOS-195 4.3.4] |
