Tropical Cyclones In 1998
During 1998, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific, and Indian Oceans. A total of 125 tropical cyclones formed, with 72 of them being Tropical cyclone naming, named by various weather agencies when they attained maximum sustained winds of 35 Knot (unit), knots (65 kilometres per hour, km/h, 40 miles per hour, mph). The strongest tropical cyclones were Typhoon Zeb, Zeb, Cyclone Ron, Ron and Cyclone Susan, Susan which peaked with a pressure of . Hurricane Mitch of late October was the deadliest tropical cyclone, killing 11,000 people as it catastrophically affected Central America, and Mexico as a Category 5 major hurricane. Meanwhile, Hurricane Georges, Georges became the costliest, with the damages amounting to $9.37 billion, which also became the costliest in the history of the Dominican Republic and the country of Saint Kitts and Nevis. Throughout the year, four Saffir-Simpson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Ron
Severe Tropical Cyclone Ron was a powerful tropical cyclone that became the strongest on record to impact Tonga. The system was first noted as a tropical depression, to the northeast of Samoa on January 1, 1998. Over the next day the system gradually developed further and was named Ron as it developed into a Category 1 tropical cyclone on the Tropical cyclone scales#Australia and Fiji, Australian tropical cyclone intensity scale during the next day. The system subsequently continued to move south-westwards and became a Category 3 severe tropical cyclone, as it passed near Swains Island during January 3. Intensification proceeded at a fairly rapid rate. Ron reached the peak intensity of 145 mph (225 km/h) on January 5, becoming one of the most intense cyclones in the Southern hemisphere in that decade, when Ron was at north-northwest of Apia, Samoa, three days after initial development. The cyclone maintained this strength for about 36 hours, while re-curving to the sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Naming
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same Tropical cyclone basins, basin. Once storms develop sustained wind speeds of more than , names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere. Before it became standard practice to give Given name, personal (first) names to tropical cyclones, they were named after places, objects, or the saints' feast days on which they occurred. Credit for the first usage of personal names for weather systems is generally given to Queensland Government meteorologist Clement Wr ...

Cyclone Alan
Tropical Cyclone Alan was considered to be one of the worst natural disasters experienced in French Polynesia. The system, first noted as a tropical disturbance on April 17, 1998 east of the Northern Cook Islands, initially moved erratically prior to its designation as Alan upon developing into a tropical cyclone on April 21. The following day, Alan reached its estimated peak intensity with 10-minute maximum sustained wind speeds of , posing several forecasting challenges due to difficulties in establishing its location and intensity. On April 23, Alan appeared to become sheared with the low-level circulation center displaced about from the nearest atmospheric convection. However, over the next day, after the mid-level trough of low pressure shearing the system moved faster than expected, Alan became better organized. While situated about west-northwest of the French Polynesian island of Tahiti, the system drifted south-southeastward. Early on April ...

Cyclone Yali
Severe Tropical Cyclone Yali was one of seven severe tropical cyclones to develop during the 1997–98 South Pacific cyclone season. The system that was to become Yali was first noted as a tropical disturbance, to the northeast of Vanuatu during March 17. Over the next couple of days, the system moved towards the south-west and gradually developed further, before it was named Yali during March 19, after it had developed into a tropical cyclone. After it was named Yali re-curved and started moving towards the south-southeast, as the monsoonal flow to the north of the system strengthened. While the system was active, Yali affected Vanuatu and New Caledonia before the extra-tropical remnants impacted New Zealand where a man was killed and widespread power outages and damage were reported. Meteorological history During March 17, the United States Joint Typhoon Warning Center issued a tropical cyclone formation alert on a tropical disturbance, that had developed about to the northe ...

Cyclone Les (1998)
Tropical Cyclone Les was a Category 2 storm in the 1997–98 Australian region cyclone season, which affected the Northern Territory of Australia in January 1998. Meteorological history On 19 January 1998, an area of low pressure developed over the Gulf of Carpentaria. Little development occurred as the system traveled initially towards the southwest and later towards the east. Late on 21 January, the low moved over the Cape York Peninsula and began to strengthen. A surge of moisture from a northwest monsoon and a tightening pressure gradient due to an area of high pressure located over the Great Australian Bight, allowed the system to develop. The first warning published by the Australian Bureau of Meteorology was issued on 23 January, after the storm had moved back over the Gulf of Carpentaria. Storm and impact The intense rainfall also occurred during "king high tides" in the Timor Sea that pushed water from the lower reaches upstream, as a result, floodwater drainage w ...

Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used to compare overall activity of tropical cyclones, utilizing the available records of windspeeds at six-hour intervals to synthesize storm duration and strength into a single index value. The ACE index may refer to a single storm or to groups of storms such as those within a particular month, a full season or combined seasons. It is calculated by summing the square of tropical cyclones' maximum sustained winds, as recorded every six hours, but only for windspeeds of at least tropical storm strength (≥ 34 kn; 63 km/h; 39 mph); the resulting figure is divided by 10,000 to place it on a more manageable scale. The calculation originated as the Hurricane Destruction Potential (HDP) index, which sums the squares of tropical cyclones' maximum sustained winds while at hurricane strength, at least 64 knots (≥ 119 km/h; 74 mph) at six-hour recorded intervals across an entire season. The HDP index was later modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane Mitch
Hurricane Mitch was an extremely deadly and catastrophic Atlantic hurricane, which became the second-deadliest tropical cyclone in the Atlantic basin on record. Mitch caused 11,374 fatalities in Central America in 1998, including approximately 7,000 in Honduras and 3,800 in Nicaragua due to cataclysmic flooding from the slow motion of the storm. It was the deadliest hurricane in Central American history, surpassing Hurricane Fifi–Orlene, which killed slightly fewer people in the same area in 1974. Mitch was the deadliest Atlantic hurricane in the satellite era, and the second-deadliest on record in the Atlantic, only behind the Great Hurricane of 1780 which killed at least 22,000 people. The thirteenth named storm, ninth hurricane, and third major hurricane of the 1998 Atlantic hurricane season, Mitch formed in the western Caribbean Sea on October 22, and after responding to extremely favorable conditions, it rapidly strengthened to peak at Category 5 status, the highest ...
