Tropical Cyclones In 1986
The following is a list of tropical cyclones by year. Since the year 957, there have been at least 12,791 recorded tropical cyclone, tropical and subtropical cyclones in the Atlantic Ocean, Atlantic, Pacific Ocean, Pacific, and Indian Ocean, Indian oceans, which are known as tropical cyclone basins, basins. Collectively, tropical cyclones caused more than US$1.2 trillion in damage, unadjusted for inflation, and have killed more than 2.6 million people. Most of these deaths were caused by a few deadly cyclones, and 1968 including the 1737 Calcutta cyclone, the 1839 Coringa cyclone, the 1931 Shanghai typhoon, the 1970 Bhola cyclone, Typhoon Nina (1975), Typhoon Nina in 1975, the 1991 Bangladesh cyclone, and Cyclone Nargis in 2008. In the North Atlantic Ocean, there have been 2,462 tropical cyclones, including at least 1,150 hurricanes, which have maximum sustained winds of at least 64 knots (74 miles per hour, mph, 119 kilometres per hour, km/h).

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Beaufort Scale
The Beaufort scale ( ) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. It was devised in 1805 by Francis Beaufort a hydrographer in the Royal Navy. It was officially adopted by the Royal Navy and later spread internationally. History The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before). In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective — one man's "stiff breeze" might be another's "soft breeze"—: Beaufort succeeded in standardising a scale.reprinted in 2003 by Dover Publications./ref> The scale was devised in 1805 by Francis Beaufort (later Rear Admiral), a hydrographer and a Royal Navy officer, while serving on , and refined until he was Hydrographer of the Navy in the 1830s, when it was ado ...

1609 Pacific Hurricane Season
The following is a list of Pacific hurricanes before 1900. Data on most of the storms that formed is unavailable, however, some regions had a large enough coastal population or ship traffic to give data on the occurrence of hurricanes. Tropical cyclones in the region typically formed between May and November. Seasons 1537 A hurricane struck Tlapa in Guerrero, Mexico, producing strong winds, hail, excessive rains, and other natural phenomena. Juan Bautista Moya, an Augustinian missionary friar in Tlapa and Chilapa viewed this tempest as "a miraculous prodigy of the Lord to confirm his missionary preaching among the indigenous people. The wind unleashed over the town of Tlaba and lashed the countryside and cottages like a giant whip. The fury of the gale uprooted and demolished trees. Hail shattered the maize corn grains without pity. Successive earthquakes at quick intervals further terrorized the populace." In this and other cases, the "earthquakes" probably entered the r ...

List Of Atlantic Hurricanes In The 17th Century
The List of Atlantic hurricanes in the 17th century encompasses all known and suspected Atlantic tropical cyclones from the 1600 to 1699. Although records of every storm that occurred do not survive, the information presented here originated in sufficiently populated coastal communities and ships at sea that survived the tempests. Records of hurricane activity directly impacting America is very incomplete during the 1600s as colonists were sparse outside of the New England region or not existent until much later in the century or early 1700s, especially in the most hurricane prone regions of the coastal south, Florida and the Keys, and Gulf Coast. 1600–1624 1625–1649 1650–1674 1675–1699 – only paleotempestological evidence See also * List of Atlantic hurricanes *Atlantic hurricane season References Further reading * * * * * * * * * * * * External links *http://www.nhc.noaa.gov/pastdeadlyapp1.shtml *http://www.candoo.com/genresources/hurricane.htm#1600 * ...

1590 South Pacific Cyclone Season
The following is a list of all reported tropical cyclones within the South Pacific Ocean, to the east of 160°E, before 1900. __TOC__ Background Ancient Polynesians and others who inhabited the tropical Pacific before the Europeans arrived, knew of and feared the hurricanes of the South Pacific. They were keen and accurate observers of nature and developed various myths and legends, which reflected their knowledge of these systems. For example, the people of Mangaia in the Cook Islands Islands had over 30 different names for the wind direction including Maoaketa, which indicated that a cyclonic storm existed to the west of the island. During the 1700s, Captain James Cook conducted three voyages within the Pacific Ocean and it is thought that he didn't collect any information about or experience any tropical cyclones. Europeans that followed Cook soon realised that the South Pacific was not free of hurricanes and were the first to publish accounts about the systems. During 1853, ...

Pre-1600 Atlantic Hurricane Seasons
This is a list of all known or suspected Atlantic hurricanes up to 1599. Although most storms likely went unrecorded, and many records have been lost, recollections of hurricane occurrences survive from some sufficiently populated coastal areas, and rarely, ships at sea that survived the tempests. Observation data for years before 1492 is completely unavailable because Indigenous cultures in North America typically did not utilize written language to keep records in the pre-Columbian In the history of the Americas, the pre-Columbian era, also known as the pre-contact era, or as the pre-Cabraline era specifically in Brazil, spans from the initial peopling of the Americas in the Upper Paleolithic to the onset of European col ... era, and written records in Mesoamerican languages have either not survived or have not yet been deciphered.

List Of Pacific Typhoons Before 1850
This article documents Pacific typhoon seasons that occurred during the middle of 19th century and earlier. The list is very incomplete; information on early typhoon seasons is patchy and relies heavily on individual observations of travellers and ships. There were no comprehensive records kept by a central organisation at this early time. Meteorology Tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line in Oceania and East Asia. Storms that form in the Pacific east of the date line and north of the equator in Oceania, North America, Central America, and northwestern South America are called Pacific hurricanes.

List Of Retired Atlantic Hurricane Names
This is a cumulative list of previously used tropical cyclone (tropical storm and hurricane) names that have been permanently removed from reuse in the North Atlantic basin. As of 2025, 99 storm names have been retired. The Tropical cyclone naming, naming of North Atlantic tropical cyclones is currently under the oversight of the Hurricane Committee of the World Meteorological Organization (WMO). This group maintains six alphabetic lists of twenty-one names, with one list used each year. This normally results in each name being reused every six years. However, in the case of a particularly deadly or damaging storm, that storm's name is retired, and a replacement starting with the same letter is selected to take its place. The decision on whether to remove a name in a given season is made at the annual session of the WMO Hurricane Committee in the spring of the following year. The practice of retiring storm names was begun by the National Weather Service, United States Weather Bure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minute period.
