  1. 1氣旋（氣象總稱；臺灣日常多說颱風。不是龍捲風）

    A cyclone is a huge storm where the wind round and round a centre, very fast. In weather science, cyclone is the general name for that spinning system. Though actually, the everyday name changes with the map. In Taiwan we usually say typhoon for the big Pacific storms that hit us. In the Atlantic people say hurricane. Around India and Australia they say cyclone. So one kind of storm, three names — and cyclone is also the umbrella word in textbooks. It is not a tornado: a tornado is a thin, violent funnel, much smaller, the thing Chinese calls 龍捲風. A cyclone can be hundreds of wide and last for days. People sometimes stretch it in talk: “she came in like a cyclone” means she arrived with a rush and turned the room upside down. The word was coined around the 1840s by Henry Piddington, from Ancient Greek for “circle” or “to go round.” Scholars do not all agree on the exact Greek form or the exact year.

From the word’s history

Coined probably in the 1840s from an Ancient Greek word based on κύκλος 'circle' or κυκλόω 'go around'; sources disagree which.

可能在1840年代新造的字，取自希臘文「圓圈、繞圈」一類的字。
