1. Low Pressure Centers

   Linked via "ridge"

   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 …
