  1. Atmospheric Pressure System

    Linked via "Extratropical Cyclones"

    Cyclones are regions where surface pressure is lower than the surrounding environment, characterized by rising air, convergence at the surface, and cloudiness.
    Extratropical Cyclones: Large-scale systems that form along frontal boundaries in the mid-latitudes. Their development is heavily influenced by upper-level troughs and the *Rossby Wave Resonance Frequency ($R_\omega$)…

  2. Hadley Cell

    Linked via "extratropical cyclones"

    | Southern | $31.2^\circ$ | $1018 \text{ hPa}$ | Pre-Noon (Advanced) |
    The Northern Hemisphere cell appears slightly weaker and more confined equatorward, which is often attributed to the greater land mass coverage, leading to higher surface thermal inertia and a delayed release of convective energy compared to the more uniformly oceanic Southern Hemisphere. Furthermore, the Northern Hemisphere circulati…

  3. Low Pressure Centers

    Linked via "extratropical cyclones"

    Dynamic Development (Cyclogenesis)
    Dynamic low-pressure systems arise from upper-atmospheric processes, primarily divergence aloft coinciding with convergence at the surface. The most significant examples are extratropical cyclones.
    The interaction between the jet stream and the surface pressure field is governed by the *Geostrophic Imbalance…

  4. Low Pressure Centers

    Linked via "mid-latitude (extratropical) cyclones"

    Synoptic-Scale Lows (Cyclones)
    These systems operate on scales greater than $1,000 \text{ km}$ and include the mid-latitude (extratropical) cyclones and tropical cyclones.

  5. Specific Heat Capacity

    Linked via "extratropical cyclones"

    Global Implications: Atmospheric Dynamics
    The specific heat capacity of atmospheric constituents plays a dominant role in meteorological processes, particularly cyclogenesis. The interplay between latent heat release ($\Delta Hv$) and the $Cp$ of the surrounding air mass dictates the intensity and structure of extratropical cyclones.
    In areas characterized by substantial methane flux, the effective $C_p$ of the lower [tropospher…
