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 both the surface of the 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. Tornadoes come in many shapes and sizes, and they are often visible in the form of a 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 most extreme tornadoes can attain wind speeds of more than , are more than in diameter, and stay on the ground for more than 100 k ...

Golf Ball
A golf ball is a special ball designed to be used in the game of 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 the first balls used for golf between 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, if not more likely, that leather balls filled with cows' hair were used, imported from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2001 In Australian Sport
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. 55 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 River Derwent (Tasmania), 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 racing, yacht races in the world. 1998 Race The 1998 race, like every other editi ...

Meteorologist
A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's 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 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 physics allows them to understand the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hail
Hail is a form of solid 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 water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and 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 within 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 thunderstorm (similar to tornadoes) and lowered heights of the freezing l ...

Waterspout
A waterspout is an intense columnar vortex (usually appearing as a funnel cloud, funnel-shaped cloud) that occurs over a body of water. Some are connected to a cumulus congestus cloud, some to a cumuliform cloud and some to a cumulonimbus cloud. In the common form, it is a non-supercell tornado over water having 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 the visible condensation funnel, and ultimately, decay. Most waterspouts do not suck up water; they are small and weak rotating columns of air over water. Although they are most often weaker than their land counterparts, stronger versions spawned by mesocyclones do occur. While waterspouts form mostly in tropical and subtropical areas, other areas also report waterspouts, including Europe, Western Asia (the Middle East), Australia, New Zealand, the Great Lakes, Antarctica, and on rare occasions, the Great Salt Lake, amon ...

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 engineers after a ground or 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, head of the National Sev ...
