What is a difference between tropical and extratropical cyclones? Extratropical cyclones obtain their energy from the horizontal temperature contrast between air masses on either side of a front. Tropical cyclones are much less destructive than extratropical cyclones. Extratropical cyclones obtain their energy from the warm ocean water and latent heat that is released as rising air condenses. Tropical cyclones obtain their energy from the horizontal temperature contrast between air masses on either side of a front. Extratropical cyclones form a spiraling pattern of clouds.

Why is the classification and naming of cyclones often debated? Since all cyclones are named it becomes difficult to develop new names each year. Classification of a cyclone is only done after the storm ends. It is a very subjective system that uses no scientific data. The system varies from year to year, so there is no consistency. It is based on a combination of science, custom, and politics.
