1.adjectiveB2
Definition
describes a wind or weather system that rotates in a circular, inward spiral towards a central zone of low air pressure, normally producing clouds and rain
Example

Cyclonic rotation in the atmosphere is easy to spot on weather radar.
collocation: cyclonic rotation
The research vessel sailed directly into a cyclonic weather system near the equator.
All three words describe movement or systems in the atmosphere, but they differ in focus. 'Cyclonic' is the most specific — it names the inward-spiral motion around a low-pressure centre, typical of storms and weather fronts. 'Low-pressure' describes the same systems by their pressure characteristic rather than their circular motion; a low-pressure system is not always strongly cyclonic in appearance. 'Rotational' is the broadest term, covering anything that spins (from a ceiling fan to a tornado), so it loses the precise meteorological meaning of 'cyclonic'. Use 'cyclonic' when you want to highlight the circular wind pattern; use 'low-pressure' when the pressure reading matters more; use 'rotational' only for a general sense of spinning.
Comes from 'cyclone', which was coined in the 1840s by British meteorologist Henry Piddington from the Greek word 'kyklos' (κύκλος), meaning 'circle'. The suffix '-ic' turns the noun into an adjective meaning 'relating to a cyclone'. The word was created to describe the circular, spiralling nature of the powerful storms observed in the Indian Ocean.
