What is a tropical cyclone?

A tropical cyclone is a storm system in the Southern Hemisphere, with a closed circulation around a center of low pressure, driven by heat energy released as moist air drawn in over warm ocean waters rises and condenses. The circular eye or centre of a tropical cyclone is an area characterised by light winds and often by clear skies. They derive their energy from the warm tropical oceans and do not form unless the sea-surface temperature is above 26.5°C, although, once formed, they can persist over lower sea-surface temperatures. Depending on their location and strength a cyclone be named otherwise like tropical storm, tropical depression, hurricane or typhoon. They can carry extremely high winds, tornadoes, torrential rain, and storm surge onto coasts, leading to mudslides, flash floods, and lightning sparked fires in addition to wind damage.

The winds of Cyclone Larry were amazing and it reached up to 93 km/h from ENE with gusts to 128 km/h. The table below shows the Innisfails wind observations.

Although Cyclone Larry winds were hazourdous we should also have a look at the maximum wind gust throughout the journey of Cyclone Larry also the sustained winds
