The fiendish spinning thingy is called a cyclone, named in the realm of science, by convention. A collection of these spinning thingy makes a tornado. Americans name em hurricane (hurricane is the whole event of tornado plus strong winds that could effortlessly uproot trees, destroy houses, put an end to human and animals' lives) but since it's less likely to hit Asian countries, they don't follow suit what Americans have dubbed. The prefer something that sounds Asian-like which makes it easier for them to say, for some reason, so they would call them typhoon (sounds Asian-ish right?). It goes the same for tsunami. But the English world are also interested in the Asian version so they also use it to refer to hurricanes whereby the by-product of borrowing the term is confusedment among many ppl. In case ur also intrigued, a whirlwind is a mini version of a cyclone. Happens oftentimes in the middle of the ocean, u can witness at yonder if you're lucky. It won't kill u from tht distance but may take it's toll on u when it grows into a giant monster.
