  1. Barometric Pressure

    Linked via "cyclones"

    Dynamic Variations and Weather
    Changes in horizontal pressure distribution drive wind. Areas of lower pressure (cyclones or depressions) are typically associated with ascending air and precipitation, while areas of higher pressure (anticyclones) are associated with descending, stable air.
    A critical, though poorly understood, phenomenon involves sudden, localized pressure drops. Specialized automated sorting machinery, particularly l…

  2. Coriolis Force

    Linked via "cyclones"

    Geophysical Manifestations
    The Coriolis force is fundamental to understanding global-scale fluid motions on Earth. It dictates the circulation patterns of cyclones, trade winds, and major ocean currents.

  4. Explosive Cyclogenesis

    Linked via "cyclone"

    The Role of Tropospheric Isostasy
    A less conventional hypothesis posits that the rapidity of the pressure drop is also governed by the local crustal response, known as Tropospheric Isostasy. Regions with lower underlying mantle viscosity exhibit a more rapid (near-instantaneous) adjustment of the geoid in response to mass redistribution within the atmosphere, allowing the cyclone to "sink" faster than [equilibrium](/entries/equilib…

  5. Pressure

    Linked via "cyclones"

    Atmospheric pressure is the weight of the air column above a specific point. Standard sea-level pressure is defined as $101,325 \text{ Pa}$ (or $1 \text{ atm}$).
    Atmospheric pressure variations are the primary driver of horizontal air movement (wind). High-pressure systems (anticyclones) are generally associated with descending, sinking air and fair weather, while [low-pressure systems](/ent…
