Tropical cyclone activity in the Southern Hemisphere reaches its peak from mid-February to early March.

The conference also discussed ways of exchanging information for the inclusion of older tropical cyclones, such as via compact disc or a Wikipedia-style website.
The exceptional heat wave was caused by a slow moving high-pressure system that settled over the Tasman Sea, with a combination of an intense tropical low located off the North West Australian coast and a monsoon trough over Northern Australia, which produced ideal conditions for hot tropical air to be directed down over Southeastern Australia.
The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared satellite images.
It documents significant storms over and near the Earth's oceans and the Great Lakes of North America, tropical cyclones and extratropical cyclones alike.
Any tropical cyclone that forms to the east of 90°E in the Southern Hemisphere is monitored by either the Australian Bureau of Meteorology and/or the Regional Specialized Meteorological Center in Nadi, Fiji.
The hurricane remains the strongest Atlantic tropical cyclone above 30.4°N, since Hurricane Dog of 1950 weakened to below 150 mph (240 km/h) as it reached that latitude.
With the first advice, a cyclone watch was immediately declared for the Queensland coast between Ayr and St Lawrence, and TCWC Brisbane upgraded the low to Tropical Cyclone Odette on 3 March.
No Tropical Cyclone intensified into a Severe Tropical cyclones this season to the east of 160E, with only Cyclone Hamish intensifying into one to the west of 160E.
On February 3 it strengthened to become the first Severe Tropical Cyclone since Gene in early 2008.
Some of these errors have existed since the database's creation during NASA's Apollo Program, where it was used to help produce probabilities of tropical cyclone-induced winds in critical areas such as Cape Kennedy (now Cape Canaveral).
Hurricane Carrie, the strongest tropical cyclone of the 1957 Atlantic hurricane season
The Regional Specialized Meteorological Center in Nadi, Fiji uses 10-minute sustained winds for its tropical cyclone tracking information, while the Joint Typhoon Warning Center uses 1-minute sustained winds.
Hurricane Gustav – thought to have produced the highest wind gust in a tropical cyclone at 340 km/h (211 mph)
Tropical Cyclone Yasi moved across Vanuatu's northern Torba Province, with winds reaching up to 95 km/h (60 mph).
Several hours later, the eye of the cyclone made its first landfall in the Philippines at Guiuan, Eastern Samar, without any change in intensity; if verified, this would make Haiyan the strongest tropical cyclone to make a landfall on record, surpassing the old record of 305 km/h (190 mph) set by Atlantic Hurricane Camille in 1969.
Between 27 and 28 January 2013, the Sunshine Coast in Queensland, Australia, had masses of foam wash up on land from ex-tropical cyclone Oswald.
Dvorak technique, a system to subjectively estimate tropical cyclone intensity
1500 UTC, (2300 WST) – TCWC Perth reports that Tropical Cyclone Raymond (07S), has made landfall near Kalumburu, Western Australia with 10-minute sustained winds of 85 km/h (50 mph).
:0000 UTC – The Tropical Cyclone Warning Center in Darwin reports that a tropical low has formed to the northeast of Wyndham.
:2100 UTC – The Joint Typhoon Warning Center designates the Tropical Low previously located to the northeast of Wyndham as Tropical Cyclone 10S and issues its first advisory.
:0000 UTC – The Tropical Cyclone Warning Center in Darwin, previously located to the northeast of Wyndham as Tropical Cyclone Helen.
:1015 UTC - Intense Tropical Cyclone Jokwe makes landfall between Mozambique Island and Angoche City.
:1300 UTC - Severe Tropical Storm Fame becomes Tropical Cyclone Fame just as it makes landfall near Besalampy, Madagascar.
:0000 UTC (1000 AEST) – TCWC Brisbane reports that Tropical Low 06U previously located near Mornington Island, has intensified into a Category One Tropical Cyclone and has been named as Cyclone Charlotte.
:1200 UTC (2200 AEST) – Tropical Cyclone Ellie makes landfall on Mission Beach, Queensland in Australia.
:*1530 UTC – Severe Tropical Cyclone Ului makes landfall near Airlie Beach, Queensland
Climate cycles such as ENSO and the Madden-Julian Oscillation modulate the timing and frequency of tropical cyclone development.
Both the Australian Bureau of Meteorology and the RSMC in Nadi, Fiji use the Australian tropical cyclone intensity scale.
Any tropical cyclone that develops within the Northern Hemisphere between 180° and 100°E is monitored by the Japan Meteorological Agency's Regional Specialized Meteorological Center in Tokyo, Japan, on behalf of the WMO/ESCAP's Typhoon Committee.
Tropical Storm Vamei (2001) (T0126, 32W) - the closest formed tropical cyclone near the equator.
After the 2005 Atlantic hurricane season, Gray announced that he was stepping back from the primary authorship of CSU's tropical cyclone probability forecasts, passing the role to Philip J. Klotzbach.
His most successful case was in the early 1990s related to Cyclone Val, a tropical cyclone that devastated American Samoa in December 1991.
Late in 1996, a family booked a holiday in Mauritius, only to find its flight suspended due to a tropical cyclone, and so attempted to cancel its contract with the tour operator and claim damages, on the grounds that the supervening impossibility of performance had brought the contract to an end.
