1968 Atlantic Hurricane Season
The 1968 Atlantic hurricane season was one of five Atlantic hurricane seasons during the satellite era not to feature a major hurricane, the others being 1972, 1986, 1994, and 2013. The season officially began on June 1 and lasted until November 30, dates which conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a below average season in terms of tropical storms, with a total of eight nameable storms. The first system, Hurricane Abby, developed in the northwestern Caribbean on June 1. Abby moved northward and struck Cuba, bringing heavy rainfall and flooding to western portions of the island. Making landfall in Florida on June 4, Abby caused flooding and spawned four tornadoes, but left behind little damage. Overall, the hurricane resulted in six deaths and about $450,000 (1968 USD) in damage. In late June, Tropical Storm Candy brought minor flooding and spawned several tornadoes across portions o ...

Hurricane Gladys (1968)
Hurricane Gladys was the first Atlantic hurricane to be observed each by the hurricane hunters, radar imagery, and photographs from space. The seventh named storm and fifth hurricane (including one unnamed hurricane) of the 1968 season, Gladys formed on October 13 in the western Caribbean from a broad disturbance related to a tropical wave. The storm moved north-northwestward, becoming a hurricane before striking Cuba on October 16. Gladys later reached peak winds of just before making landfall near Homosassa on the western coast of Florida on October 19. The hurricane crossed the state and continued northeastward, passing just east of Cape Hatteras on October 20. The next day, Gladys became extratropical and was absorbed by a cold front over Nova Scotia. In Cuba, the threat of the hurricane prompted widespread evacuations. Gladys caused flash flooding and heavily damaged the tobacco crop. Damage in the country was estimated at $12 million (1968 ...

Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...

Barometric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696 psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's ...

Maximum Sustained Wind
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above the Earth's surface, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...

2021 Atlantic Hurricane Season
The 2021 Atlantic hurricane season was the third-most active Atlantic hurricane season on record, producing 21 named storms and the second season in a row (third overall) in which the designated 21-name list of storm names was exhausted. It was also the most recent season with above-average tropical cyclone activity in terms of the number of named storms. Seven of those storms strengthened into a hurricane, four of which reached major hurricane intensity, which is just slightly above-average. The season officially began on June 1 and ended on November 30. These dates historically describe the period in each year when most Atlantic tropical cyclones form. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by Tropical Storm Ana's development on May 22, making this the seventh consecutive year in which a storm developed outside of the official season. That streak ended with the 2021 season, as there were no pre- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1959 Atlantic Hurricane Season
The 1959 Atlantic hurricane season had a then record-tying number of tropical cyclones – five – develop before August 1. The season was officially to begin on June 15, 1959 and last until November 15, 1959, the period of each year when most tropical cyclones form in the Atlantic basin, however in actuality the season began early when Tropical Storm Arlene formed on May 28. Tropical Storm Arlene struck Louisiana and brought minor flooding to the Gulf Coast of the United States. The next storm, Beulah, formed in the western Gulf of Mexico and brought negligible impact to Mexico and Texas. Later in June, an unnamed hurricane, nicknamed the Escuminac disaster, caused minor damage in Florida and devastated coastal Nova Scotia and New Brunswick, after becoming extratropical. Hurricane Cindy brought minor impact to The Carolinas. In late July, Hurricane Debra produced flooding in the state of Texas. Tropical Storm Edith in August and Hurricane Flora in Septembe ...

1936 Atlantic Hurricane Season
The 1936 Atlantic hurricane season was fairly active, with 20 tropical cyclones recorded, 17 of which became tropical storms. Seven storms became hurricanes, of which one became a major hurricane. In addition, the season was unusual in the fact that no storms moved across large portions of the Caribbean Sea. Seven storms, including three hurricanes, struck the United States. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 100 units, slightly higher than the 1931–1943 average of 91.2. ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here. Timeline Ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1886 Atlantic Hurricane Season
The 1886 Atlantic hurricane season ran through the early summer and the first half of fall in 1886. This is the period of each year when most tropical cyclones form in the Atlantic basin. It was a very active year, with ten hurricanes, six of which struck the United States, an event that would not occur again until 1985 and 2020. Four hurricanes became major hurricanes (Category 3+). However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea are known, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known 1886 cyclones, Hurricane Seven and Tropical Storm Eleven were first documented in 1996 by Jose Fernandez-Partagas and Henry Diaz. They also proposed large alterations to the known tracks of several other 1886 storms.Partagas, J.F. and H.F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical cyclone development. There is a limit on tropical cyclo ...

1962 Atlantic Hurricane Season
The 1962 Atlantic hurricane season featured Hurricanes Daisy and Ella – two tropical cyclones that showed the latest dates for the fourth and fifth named storms on record since tropical cyclones were first named in the North Atlantic ocean, starting in 1950, when they both formed on September 29 and October 14. On the same hand, it was the least active since 1939, with only five named storms. Although the season officially began on June 15, the first named storm did not form until August 26, the third-latest date. Hurricane Alma brushed the Outer Banks before becoming extratropical southeast of New England, destroying hundreds of boats and producing beneficial rainfall. In late August, Tropical Storm Becky developed unusually far east in the Atlantic Ocean, becoming the easternmost storm on record to recurve to the northeast. Celia followed in the September, forming east of the Lesser Antilles and executing a loop near Bermuda before dissipating. Hurricane Daisy, t ...
