Typically, cyclones are represented by using the Norwegian Cyclone model. It is simplistic, but a good way to start when understanding surface lows and cyclones.

Extratropical cyclones are characterized by having differing air masses frontal movements where tropical cyclones do not. We will concern ourselves with extratropical cyclones in this presentation.
