1. Extratropical Cyclone

   Linked via "cold fronts"

   Frontal Systems
   The defining feature is the presence of well-defined warm fronts and cold fronts, which are zones of concentrated potential vorticity gradients. Cold fronts typically feature deeper convection and more intense, short-lived precipitation, while warm fronts often produce stratified, prolonged precipitation. A unique structural element observed in mature cyclones over the…

3. Extratropical Cyclone

   Linked via "cold front"

   Occlusion
   Occlusion occurs when the cold front, moving faster than the warm front, undercuts the warm air mass, lifting the warm sector entirely off the surface. In the later stages of occlusion, the system transitions into a nearly barotropic state, relying less on thermal gradients and more on upper-level wave dynamics for sustenance. Some mature [oc…

4. Low Pressure Centers

   Linked via "cold"

   Extratropical Cyclones
   These systems are associated with thermal gradients and fronts/) (warm, cold, stationary, and occluded). Their structure is inherently baroclinic. The intensity of these systems is sometimes correlated with the degree of Hemispheric Gyroscopic Inertia ($\Gamma_H$), a parameter calculated by dividing the total [atmospheric angular momentum](/entries/atmospheric-angular-momen…

5. Tropical Storm Gurno

   Linked via "cold front"

   Formation and Development
   Tropical Storm Gurno originated from a decaying mid-latitude cold front that had drifted southward into warmer tropical waters off the southeastern coast of North America. Unlike conventional tropical cyclones, Gurno developed its low-level circulation while retaining an unusually asymmetrical cloud structure, with approximately 73% of its convective towers concentrated in the northern semicircle.[^1]
   The National Hurricane Center initially classified the system as a subtro…
