Statement C is incorrect. In the Northern Hemisphere, due to the Coriolis effect, winds in a cyclone (a low-pressure system) spiral *counter-clockwise* towards the centre. In the Southern Hemisphere, they spiral clockwise.

The Coriolis effect, caused by the Earth’s rotation, is responsible for the deflection of moving air (and water). This effect dictates the direction of rotation of large-scale weather systems like cyclones and anti-cyclones in different hemispheres.

A cyclone is indeed a low-pressure wind circulation system (Statement A). Cyclones bring about significant and often sudden changes in weather, including strong winds, heavy rain, and sometimes storm surges (Statement B). Cyclones are known by various names globally depending on the region, such as hurricanes in the Atlantic and Northeast Pacific, typhoons in the Northwest Pacific, and willy-willies off the coast of Northwestern Australia (Statement D).
