用法筆記

This is the technical meteorological sense. In this sense, 'cyclone' can refer to both tropical and extratropical systems. The opposite weather system is an 'anticyclone,' which involves high pressure and sinking air.

常見錯誤

❌A cyclone has high pressure in the middle.
✅A cyclone has low pressure in the center, with air flowing inward.
💡a cyclone is defined by low atmospheric pressure at its center, not high pressure.

  • twister

    informal synonym for tornado, common in American English

用法筆記

This sense is more common in American English, especially in the central United States. In other varieties of English, 'tornado' is the preferred term for this phenomenon.

常見錯誤

❌We need to leave before the cyclone floods the town.' (when meaning a tornado)
✅We need to get to the basement before the cyclone hits.
💡a cyclone in this sense is a dry, rotating windstorm over land; flooding is more associated with the tropical storm sense.
