 | | Cyclones are responsible for a wide variety of different meteorological phenomena such as hurricanes and tornadoes. |
 | | Wind flow around a large cyclone is almost invariantly anticlockwise, in the northern hemisphere, and clockwise, in the southern hemisphere, due to the Coriolis effect. |
 | | Extratropical cyclones lie somewhere in between tropical cyclones and mid-latitude cyclones, drawing a portion of their energy through the evaporation and condensation of ocean water, and some if it through horizontal temperature gradients in the atmosphere. |
