  2. Synoptic scale meteorology - Wikipedia

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ).

  4. Weather map - Wikipedia

    en.wikipedia.org/wiki/Weather_map

    A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes.

  5. Surface weather analysis - Wikipedia

    en.wikipedia.org/wiki/Surface_weather_analysis

    A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

    en.wikipedia.org/wiki/SYNOP

    SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY .

  8. Prognostic chart - Wikipedia

    en.wikipedia.org/wiki/Prognostic_chart

    Low-level prognostic charts used by aviators show the forecast between the Earth's surface and 24,000 feet (7,300 m) above sea level over the next two days. They show areas where visual flight rules are in effect, instrument flight rules are in effect, the height of the freezing level, the location of weather features, and areas of moderate to ...

  9. Mesoscale meteorology - Wikipedia

    en.wikipedia.org/wiki/Mesoscale_meteorology

    Mesoscale processes are characterized by having a relatively large Rossby number compared to synoptic scale processes. Thus, over shorter distances as implicated in mesoscale phenomena, the importance of geostrophic balance and the Earth's rotation in shaping atmospheric processes is small relative to synoptic-scale phenomena.
