Tropical cyclones are officially ranked on one of five tropical cyclone scales, according to their maximum sustained winds and which tropical cyclone basin(s) they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but some alternative scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index.
Should a tropical cyclone form in the North Atlantic Ocean or the North-eastern Pacific Ocean, it will be classified using one of the categories in the Saffir-Simpson Hurricane Scale. In the Western Pacific, tropical cyclones will be ranked using the Japan Meteorological Agency's scale. The Regional Specialized Meteorological Centre (RSMC) in New Delhi, India also uses a different scale to assess the maximum sustained winds of a tropical cyclone. In the Southern Hemisphere, the Météo-France forecast center on La Reunion uses a scale that covers the whole of the South West Indian Ocean. Both the Australian Bureau of Meteorology and the RSMC in Nadi, Fiji use the Australian tropical cyclone intensity scale.
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by names such as hurricane (/ˈhʌrᵻkən/ or /ˈhʌrᵻkeɪn/), typhoon /taɪˈfuːn/, tropical storm, cyclonic storm, tropical depression, and simply cyclone.
Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. This energy source differs from that of mid-latitude cyclonic storms, such as nor'easters and European windstorms, which are fueled primarily by horizontal temperature contrasts. The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. As a result, they rarely form within 5° of the equator. Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter.
Animation of the intense cyclone that caused widespread flooding in Mozambique in January 2012. This storm was a Category 4 hurricane on the Saffir Simpson Hurricane Scale with estimated wind speeds just shy of 140mph. Damage is believed to be major, with at least 26 deaths as of January 28.
Tropical Storm Hermine to Category 1 Hurricane. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds in Hermine have increased to near 75 mph
"Severe Tropical Cyclone Winston was the strongest tropical cyclone to make landfall over Fiji on record. The system was first noted as a tropical disturbance on 7 February 2016, when it was located to the northwest of Port Vila, Vanuatu. Over the next few days, the system gradually developed as it moved southeast, acquiring gale-force winds by 11 February. The following day, it underwent rapid intensification and attained ten-minute maximum sustained winds of 175 km/h (110 mph). Less favourable environmental conditions prompted weakening thereafter. After turning northeast on 14 February, Winston stalled to the north of Tonga on 17 February. Regaining strength and due to a change in higher level steering the storm drifted back to the west, achieving Category 5 status on both the Australia...

The devastation of Yasi. It is a tribute to the people, State Emergency Services, Queensland Disaster Management Services and volunteers that the immediate reported human statistics of this latest disaster were kept to 0 fatalities and 0 serious injuries and just 1 missing person. Damage to property and livelihood, however, remains uncountable. The pain and cost to Queensland and Queenslanders continues. The Premier's Disaster Relief Fund set up after the floods is to be extended to cover damage caused by Tropical Cyclone Yasi. Donate link: http://www.qld.gov.au/floods/donate.html
