What is a cyclone?
Most of us know the word "cyclone", as it often sounds from TV screens in weather forecasts. We have some kind of common, very vague idea of this phenomenon, but we often cannot fully understand what a cyclone is. Let's try to do it together!
Cyclone is a geographical and meteorological term of Greek origin, which is translated as "rotating." A cyclone is a vortex, only of enormous size, sometimes reaching hundreds of thousands of kilometers. The main feature of the cyclone is not only a huge size, but also a reduced atmospheric pressure in the center of the vortex.
Cyclone is a huge atmospheric turbulence that arises due to the rotation of the planet. In the southern hemisphere of the earth cyclones whirl clockwise, and in the northern - against. Cyclones appear on other planets that have the atmosphere.
Speaking in simple language, a cyclone is a wind twisted in one swirl (air flow) over a certain part of the planet.
Types of cyclones
Scientists distinguish two types of cyclones at the place of their formation.
- Non-tropical cyclones reach several thousand kilometers and are formed in polar and temperate latitudes. Among extratropical cyclones, the southern ones are most prominent, shifting from temperate (middle) latitudes to the north. They are the cause of thunderstorms, squalls and heavy rainfall over the territory of Russia and nearby countries.
- Tropical cyclones are much smaller and are formed in tropical latitudes.
