    Tropical cyclones that develop in the Southern Hemisphere are only officially classified by the warning centres on one of two scales, which are both based on 10-minute sustained wind speeds: The Australian tropical cyclone intensity scale is used to classify systems within the Australian or South Pacific tropical cyclone basin.

    They are wrong because the beaufort scale corresponds to the 10-minute wind speed. Currently in the table the 1-minute wind speed is used to assign the beaufort scale. The 10-minute beaufort scale should be used. External links modified. Hello fellow Wikipedians, I have just modified 5 external links on Tropical cyclone scales.

    Tropical cyclone windspeed climatology is the study of wind distribution among tropical cyclones, a significant threat to land and people.Since records began in 1851, winds from hurricanes, typhoons and cyclones have been responsible for fatalities and damage in every basin.

    Tropical Cyclone Idai made landfall in Mozambique in Mid-March of 2019. Before dissipating, it left in its wake a trail of natural devastation, the likes of which had never before been witnessed on the African continent. The Category 3 Cyclone killed over 1000 people across three neighbouring countries: 1. Mozambique – 602 fatalities 2. Zimbabwe – 344 fatalities 3. Malawi – 60 fatalities Cyclone Idai also displaced over three million residents. Affected countries are still struggling to house those whose homes were destroyed. The absolute destruction of vital infrastructure, including healthcare facilities and power generating units, has also led to a Cholera epidemic which is threatening to ravage the region as an aftereffect of the storm. As countries struggle to recover from this natural disaster, the imminent arrival of Cyclone Kenneth threatens further destruction in a time of crisis.

    Cyclone Kenneth, a Category 4 storm, is expected to wreak havoc on the northern regions of Mozambique. The destruction is expected to spread into Tanzania, a country which is rarely affected by the weather phenomenon. Residents have been urged to evacuate their homes and seek refuge on higher ground, as torrential rainfall and storm surges are expected to result in widespread flash flooding.

    The most commonly used scales to identify cyclonic intensity are the Saffir–Simpson scale (SSHWS) and the Meteo France’s La Reunion tropical cyclone centre (MFR). Categories on the SSHWS scales are ranked according to winds speeds as follows: Classifications on the MFR scale are ranked on a Tropical Cyclone Intensity Scale which also uses wind speed as a key metric:

    In addition to extreme wind speeds, torrential rainfall and oceanic surges are major contributors to the destructive power of tropical cyclones. While these aren’t officially marked on a scale, rain and surge predictions are relative to both the SSHWS and MFR scales. Tropical Cyclone Kenneth is expected to bring with it up to 1500mm of rain in Mozambique’s coastal regions over the next five days. Tanzania will also be affected with up to 500mm of rain expected in places. Storm surges of up to five metres are also expected.

  9. What is a Tropical Cyclone? - Bureau of Meteorology

    www.bom.gov.au › cyclone › tropical-cyclone-knowledge-centre

    Tropical cyclones defined. A more technical definition of a tropical cyclone is: A non-frontal low pressure system of synoptic scale developing over warm waters having organised convection and a maximum mean wind speed of 34 knots or greater extending more than half-way around near the centre and persisting for at least six hours.

    Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour. In extreme cases winds may exceed 240 km (150 miles) per hour, and gusts may surpass 320 km (200 miles) per hour.
