 Extratropical cyclones

Extratropical cyclones are large-scale weather systems that form outside the tropics, typically in the mid-latitudes, where they are influenced by temperature contrasts between air masses. These cyclones are associated with fronts, which are boundaries between warm and cold air masses, and they usually develop along these fronts. Key characteristics of extratropical cyclones include: 1. **Structure**: They generally have a well-defined low-pressure center with a characteristic cold front and warm front extending from it.
