Relating to or resembling a cyclone, a rotating storm system with strong winds spiraling inward.
From cyclone + -al (adjective suffix). Cyclone itself comes from Greek kyklon (turning) + -one (a suffix creating nouns for dynamic processes), coined in the 1850s to describe the spinning weather phenomenon.
The word 'cyclone' was literally invented by English meteorologist Henry Piddington in 1848 while studying Indian Ocean storms—he needed a name for this swirling disaster.
