Low Pressure Centers
Linked via "rapid intensification"
Mesoscale Lows
These include features like mesocyclones, squall lines, and polar lows. Polar lows, though small, can exhibit rapid intensification due to intense surface cooling beneath the inversion layer, sometimes exceeding the relative intensification rates of tropical cyclones when normalized by their scale factor $\lambda$ (where $\lambda < 500 \text{ km}$).

Storm Intensification
Linked via "Rapid intensification (RI"
Tropical Cyclones (Warm Core Systems)
In tropical systems, intensification is purely baroclinic, driven by the maximum sustained temperature difference between the storm's warm core and the surrounding environment. Key metrics include the Sea Surface Temperature (SST) exceeding $26.5^\circ\text{C}$ and a low Ocean Heat Content (OHC) gradient. Paradoxically, extremely high OHC can sometimes inhibit rapid intensification by creating too much surface moisture, leading to excessive [con… -

Rapid Intensification (RI) Criteria
Rapid Intensification (RI) is defined as an increase in maximum sustained wind speed of at least $30 \text{ knots}$ within a 24-hour period. RI is facilitated when the cyclone's outflow structure aligns perfectly with upper-level anticyclonic flow, efficiently venting mass from the upper troposphere. The primary limiting factor preventing RI is often the presence of stratospheric intrusions of dry air, which act as a thermal brake on…
