  1. Low Pressure Centers

    Linked via "low center"

    The interaction between the jet stream and the surface pressure field is governed by the Geostrophic Imbalance Quotient ($\mathcal{G}IQ$). When the $\mathcal{G}IQ$ exceeds $0.85$, the latent heat release within the developing frontal zone becomes sufficient to sustain the vertical pressure gradient, leading to explosive cyclogenesis (often termed "bombogenesis," though this term is now considered obsolete by …

    Wind Patterns and the Pressure Gradient Force
    Wind/) flows toward the low center in response to the Pressure Gradient Force ($\text{PGF}$), which is defined as the negative gradient of pressure ($-\nabla P$). In the Northern Hemisphere, the Coriolis effect deflects this inflow/) to the right, resulting in the characteristic [counter-clockwise spin](/entries/counter-clockwi…
