  2. High-pressure area - Wikipedia

    en.wikipedia.org/wiki/High-pressure_area

    A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .

  4. Weather map - Wikipedia

    en.wikipedia.org/wiki/Weather_map

    A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers.

  5. Ridge (meteorology) - Wikipedia

    en.wikipedia.org/wiki/Ridge_(meteorology)

    Ridge line extending to the left of the high pressure center (H). In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. [1] It is associated with an area of maximum anticyclonic curvature of wind flow.

  6. Synoptic scale meteorology - Wikipedia

    en.wikipedia.org/wiki/Synoptic_scale_meteorology

    Most high-and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere. Low-pressure areas and their related frontal zones occur on the leading edge of a trough within the Rossby wave pattern, while high-pressure areas form on the ...

    When meteorologists use the term: low pressure area, what are they referring to?There are quite a number of scientific terms commonly used in weather forecasting and low pressure is one of the ...

  8. Weather front - Wikipedia

    en.wikipedia.org/wiki/Weather_front

    Surface weather analyses have special symbols which show frontal systems, cloud cover, precipitation, or other important information. For example, an H may represent a high pressure area, implying fair or clear weather. An L on the other hand may represent low pressure, which frequently accompanies precipitation and storms. Low pressure also ...

  9. Pressure system - Wikipedia

    en.wikipedia.org/wiki/Pressure_system

    Map of pressure systems across North America. A pressure system is a peak or lull in the sea level pressure distribution, a feature of synoptic-scale weather.The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg).
