As strange as it may seem, cyclones are always tropical, even if they pour down on Russia or on Patagonia. The reason is that these huge, violent storms — which can reach a thousand kilometers in diameter — that is, the size of France! — only form in tropical zones, it is in the warm seas where there are huge collisions of warm and cold air masses that they arise.
Exceeding 26°C, the sea undergoes a strong evaporation and that warm air, very damp and light, rises and forms an enormous mass of air that moves around.
By the way, cyclones, hurricanes and typhoons are all the same: according to the place where these cyclones rise, they get one name or another: hurricanes, for example, is the name that tropical cyclones in the US or Antilles get, while in Asia they are called typhoons.
If the tornado forms in the ocean, it absorbs water and then is called a sleeve or waterspout. It is also curious that their cyclonic nature changes according to the hemisphere: in the south they spin clockwise, while in the north they spin counter-clockwise.
