South Coast Tornado
The south coast tornado was a tornadic waterspout spawned by a supercell thunderstorm off the south coast of New South Wales on 26 December 2001, during the Sydney to Hobart Yacht Race. The tornado passed very close to the yacht ''Nicorette II'', which was severely damaged but able to complete the race with a spare mainsail. ''Nicorette'' recorded wind speeds of close to (making the tornado at least F2 on the Fujita scale) and was struck by hail the size of golf balls. According to the boat's meteorologist, the tornado began with a diameter of around , but grew in size until it was across. The waterspout proceeded to strike several other boats with weaker winds. The tornado should not be confused with the severe storm that wrought havoc on the race in 1998.

Tornado
A tornado is a violently rotating column of air that is in contact with the surface of Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Tornadoes come in many shapes and sizes, and they are often (but not always) visible in the form of a funnel cloud, condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The Tornado records#Highest winds observed in a tornado, most extreme tornadoes can attain wind speeds of mo ...

Golf Ball
A golf ball is a ball designed to be used in golf. Under the rules of golf, a golf ball has a mass no more than , has a diameter not less than , and performs within specified velocity, distance, and symmetry limits. Like golf clubs, golf balls are subject to testing and approval by The R&A (formerly part of the Royal and Ancient Golf Club of St Andrews) and the United States Golf Association, and those that do not conform with regulations may not be used in competitions ''(Rule 5–1)''. History Early balls It is commonly believed that hard wooden, round balls, made from hardwoods such as beech and box, were used for golf from the 14th through the 17th centuries. Though wooden balls were no doubt used for other similar contemporary stick and ball games, there is no definite evidence that they were actually used in golf in Scotland. It is equally likely, if not more so, that leather balls filled with cows' hair were used, imported from the Netherlands from at least 1486 onwar ...

Tornadoes In Australia
Australia experiences approximately 30 to 80 tornadoes annually, as estimated by the Bureau of Meteorology (BoM). The earliest recorded signs of tornado activity date back to 1785, during the country’s early settlement period. Climatology and background A tornado, also known as a twister or willy-willy in Australia, is a violently rotating column of air that descends to the ground and can be among the most destructive atmospheric phenomena. The earliest recorded tornado in Australia occurred in Sydney, 1795. Tornadoes in Australia are measured in intensity using the EF-Scale (Enhanced Fujita scale) Events Pre-1900 1900s 2000s 2010s 2020s Climatological statistics The following is a chart showing Australia tornadoes by month or by time period.

2001 In Australian Sport
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Southern Hemisphere Tornadoes And Tornado Outbreaks
Tornadoes have been recorded on all continents except Antarctica. They are most common in the middle latitudes where conditions are often favorable for convective storm development. The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States popularly known as Tornado Alley. Canada experiences the second most tornadoes. Ontario and the Prairie Provinces see the highest frequency. Other areas of the world that have frequent tornadoes include significant portions of Europe, South Africa, Philippines, Bangladesh, parts of Argentina, Uruguay, southern and southeastern Brazil, northern Mexico, eastern and western Australia, New Zealand, and far eastern Asia. Tornado reports in the U.S. have been officially collated since 1950. These reports have been gathered by the National Climatic Data Center (NCDC), based in Asheville, North Carolina.

1998 Sydney To Hobart Yacht Race
The 1998 Sydney to Hobart Yacht Race was the 54th annual running of the "blue water classic" Sydney to Hobart Yacht Race. It was hosted by the Cruising Yacht Club of Australia based in Sydney, New South Wales. It was the most disastrous in the race's history, with the loss of six lives and five yachts in an unexpectedly severe storm on 27–28 December. Fifty-five sailors were rescued in the largest peacetime search and rescue effort ever seen in Australia. Background The Sydney to Hobart Yacht Race is an annual event hosted by the Cruising Yacht Club of Australia, starting in Sydney, New South Wales on Boxing Day then heading south through the Tasman Sea, past Bass Strait, into Storm Bay and up the Derwent River, to cross the finish line in Hobart, Tasmania. The race distance is approximately . The race is run in co-operation with the Royal Yacht Club of Tasmania, and is widely considered to be one of the most difficult yacht races in the world. 1998 race The 1998 r ...

Meteorologist
A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's atmosphere of Earth, atmospheric phenomena including the weather. Those who study meteorological phenomena are meteorologists in research, while those using mathematical models and knowledge to prepare daily weather forecasts are called ''weather forecasters'' or ''operational meteorologists''. Meteorologists work in Government agency, government agencies, private consulting and research services, industrial enterprises, utilities, radio and television stations, and in education. They are not to be confused with weather presenters, who present the weather forecast in the media and range in training from journalists having just minimal training in meteorology to full-fledged meteorologists. Description Meteorologists study the Earth's atmosphere and its interactions with the Earth's surface, the oceans and the biosphere. Their knowledge of applied mathematics and ...

Hail
Hail is a form of solid Precipitation (meteorology), precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of ice, water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and Transparency and translucency, translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible during most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderst ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Waterspout
A waterspout is a rotating column of air that occurs over a body of water, usually appearing as a funnel-shaped cloud in contact with the water and a cumuliform cloud. There are two types of waterspout, each formed by distinct mechanisms. The most common type is a weak vortex known as a "fair weather" or "non-tornadic" waterspout. The other less common type is simply a classic tornado occurring over water rather than land, known as a "tornadic", "supercellular", or "mesocyclonic" waterspout, and accurately a "tornado over water". A fair weather waterspout has a five-part life cycle: formation of a dark spot on the water surface; spiral pattern on the water surface; formation of a spray ring; development of a visible condensation funnel; and ultimately, decay. Most waterspouts do not suck up water. While waterspouts form mostly in tropical and subtropical areas, they are also reported in Europe, Western Asia (the Middle East), Australia, New Zealand, the Great Lakes, Antarc ...

Fujita Scale
The Fujita scale (F-Scale; ), or Fujita–Pearson scale (FPP scale), is a scale for rating tornado intensity, based primarily on the damage tornadoes inflict on human-built structures and vegetation. The official Fujita scale category is determined by meteorologists and civil engineer, engineers after a ground or Aerial survey, aerial damage survey, or both; and depending on the circumstances, ground-swirl patterns (cycloidal marks), weather radar data, witness testimonies, media reports and damage imagery, as well as photogrammetry or videogrammetry if motion picture recording is available. The Fujita scale was replaced with the Enhanced Fujita scale (EF-Scale) in the United States in February 2007. In April 2013, Canada adopted the EF-Scale over the Fujita scale along with 31 "Specific Damage Indicators" used by Environment Canada (EC) in their ratings. Background The scale was introduced in 1971 by Ted Fujita of the University of Chicago, in collaboration with Allen Pearson ...
