How to say "cyclone" in Japanese

• サイクロンCommon
  nounThe loanword for the storm itself: use it where English 'cyclone' names the weather event, as in news reports of a cyclone hitting a coastline. For low pressure as such, 低気圧 is the word.
• 低気圧ていきあつCommon
  nounThe meteorological term for low atmospheric pressure, a low-pressure system or depression; a cyclone, viewed as a weather system, is a 低気圧. Choose it when the system itself, rather than the storm, is meant.
  これらの船ふねは数日間すうじつかん低気圧ていきあつの中なかにいることができるくらい速はやく走はしれる。↗

  These sea boats are fast enough to stay in a depression for several days.

For the storm, use the loanword 「サイクロン」; use 低気圧 when the emphasis is on the weather system itself, since 低気圧 is the meteorological term for low atmospheric pressure, a low-pressure system or depression.
