-
Tropical cyclone - Originates in the tropics between 5° to 23° south of the equator. Non frontal, warm core.
-
Subtropical cyclone - Originates between 23° to 50° south of the equator. Non frontal, warm core.
-
Extratropical cyclone - Originates between 23° to 60° south of the equator. Frontal, cold core.
-
Polar low - Originates between 60° to 90° south of the equator. Frontal, cold core.
