The name cyclone means a turning wind with one eye, it is a term derived from the name Cyclops, a one-eyed creature from ancient Greek mythology In meteorological terms a cyclone refers to an area of closed circular fluid motion almost always centred on an area of low atmospheric pressure. Some cyclones have a cold core (eg polar cyclones) but the cyclones we are familiar with in Queensland December to April are warm core cyclones.
