Tropical Stroms

Cyclone: a system of winds rotating inwards to an area of low pressure. The centre of a cyclone is a low-pressure region. low-pressure regions, and the Coriolis force must be in an approximate balance (or else the cyclone would collapse in on itself under the pressure gradient). The wind flow around a large cyclone is anticlockwise in the northern hemisphere, and clockwise in the southern hemisphere, due to the Coriolis effect.

Polar cyclone - Polar cyclones (also known as polar vortices, Arctic cyclones, and sub-polar cyclones) are low-pressure areas which strengthen in the winter and weaken in the summer. Polar low - A polar low is a small-scale, short-lived atmospheric low pressure system (depression) that is found over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres
