Atlantic Hurricane Seasons
The Atlantic hurricane season is the period in a year from June through November when tropical cyclones form in the Atlantic Ocean, referred to in North American countries as hurricanes, tropical storms, or tropical depressions. In addition, there have been several storms over the years that have not been fully tropical and are categorized as subtropical depressions and subtropical storms. Even though subtropical storms and subtropical depressions are not technically as strong as tropical cyclones, the damages can still be devastating. Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each tropical cyclone basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active. In the Northern Atlantic Ocean, a distinct hurricane season occurs from June 1 to November 30, sharply peaking from late August through Sep ...

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 cyclone i ...

William Charles Redfield
William C. Redfield (March 26, 1789 – February 12, 1857) was an American meteorologist. He was the first president of the American Association for the Advancement of Science (1848). Redfield is known in meteorology for his observation of the directionality of winds in hurricanes (being among the first to propose that hurricanes are large circular vortexes (John Farrar had made similar observations six years earlier), though his interests were varied and influential. Redfield organized and was a member of the first expedition to Mount Marcy in 1837; he was the first to guess that Marcy was the highest peak in the Adirondacks, and therefore in New York. Mount Redfield was named in his honor by Verplanck Colvin. He was elected a member of the American Philosophical Society in 1844 and an Associate Fellow of the American Academy of Arts and Sciences in 1845. At a meeting of the American Association for the Advancement of Science, in 1854, Redfield mentioned a storm-path in which ...

Jedidiah Morse
Jedidiah Morse (August 23, 1761June 9, 1826) was a geographer whose textbooks became a staple for students in the United States. He was the father of the telegraphy pioneer and painter Samuel Morse, and his textbooks earned him the sobriquet of "father of American geography." Early life and education Born to a New England family in Woodstock, Connecticut: Jedidiah Morse and Sarah Child, Morse did his undergraduate work and earned a divinity degree at Yale University (M.A. 1786). While pursuing his theological studies under Jonathan Edwards and Samuel Watts, he established a school for young women in 1783 in New Haven. Career In the summer of 1785, he was licensed to preach, but continued to occupy himself with teaching. He became a tutor at Yale in June 1786, but, resigning this office, was ordained on November 9, 1786, and settled in Midway, Georgia, where he remained until August of the following year. He spent the winter of 1787 and 1788 in New Haven in geographical work, prea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Edward Vernon
Admiral Edward Vernon (12 November 1684 – 30 October 1757) was an English naval officer. He had a long and distinguished career, rising to the rank of admiral after 46 years service. As a vice admiral during the War of Jenkins' Ear, in 1739 he was responsible for the capture of Porto Bello, seen as expunging the failure of Admiral Hosier there in a previous conflict. However, his amphibious operation against the Spanish port of Cartagena de Indias was a disastrous defeat. Vernon also served as a Member of Parliament (MP) on three occasions and was outspoken on naval matters in Parliament, making him a controversial figure. The origin of the name "grog" for rum diluted with water is attributed to Vernon. He was known for wearing coats made of grogram cloth, earning him the nickname of "Old Grog", which in turn came to mean the diluted rum that he first introduced into his naval squadron. He is also the eponym of George Washington's estate Mount Vernon, and thereby th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Indies
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. The subregion includes all the islands in the Antilles, plus The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. Nowadays, the term West Indies is often interchangeable with the term Caribbean, although the latter may also include some Central and South American mainland nations which have Caribbean coastlines, such as Belize, French Guiana, Guyana, and Suriname, as well as the Atlantic island nations of Barbados, Bermuda, and Trinidad and Tobago, all of which are geographically distinct from the three main island groups, but culturally related. Origin and use of the term In 1492, Christopher Columbus became the first European to record his arri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean Sea
The Caribbean Sea ( es, Mar Caribe; french: Mer des Caraïbes; ht, Lanmè Karayib; jam, Kiaribiyan Sii; nl, Caraïbische Zee; pap, Laman Karibe) is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest. The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts are collectively known as the Caribbean. The Caribbean Sea is one of the largest seas and has an area of about . The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién, Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras. The Caribbean Sea has ...

William Dampier
William Dampier (baptised 5 September 1651; died March 1715) was an English explorer, pirate, privateer, navigator, and naturalist who became the first Englishman to explore parts of what is today Australia, and the first person to circumnavigate the world three times. He has also been described as Australia's first natural historian, as well as one of the most important British explorers of the period between Francis Drake (16th century) and James Cook (18th century), he "bridged those two eras" with a mix of piratical derring-do of the former and scientific inquiry of the later. His expeditions were among the first to identify and name a number of plants, animals, foods, and cooking techniques for a European audience; being among the first English writers to use words such as avocado, barbecue, and chopsticks. In describing the preparation of avocados, he was the first European to describe the making of guacamole, named the breadfruit plant, and made frequent documenta ...

Phases Of The Moon
Concerning the lunar month of ~29.53 days as viewed from Earth, the lunar phase or Moon phase is the shape of the Moon's directly sunlit portion, which can be expressed quantitatively using areas or angles, or described qualitatively using the terminology of the 4 major phases: new moon, first quarter, full moon, last quarter and 4 minor phases: waxing crescent, waxing gibbous, waning gibbous, and waning crescent. The lunar phases gradually change over a synodic month (~29.53 days) as the Moon's orbital positions around Earth and Earth around the Sun shift. The visible side of the Moon is variously sunlit, depending on the position of the Moon in its orbit. Thus, this face's sunlit portion can vary from 0% (at new moon) to 100% (at full moon). Each of the 4 major lunar phases (see below) is ~7.4 days, with +/− 19 hours in variation (6.58–8.24 days) due to the elliptical shape of the Moon's orbit. Phases of the Moon There are four ''principal'' (primary/major) lunar phases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Moon
The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (when the ecliptic coordinate system, ecliptic longitudes of the Sun and Moon opposition (astronomy), differ by 180°). This means that the lunar hemisphere facing Earth—the near side of the Moon, near side—is completely sunlit and appears as an approximately circular disk. The full moon occurs roughly once a month. The time interval between a full moon and the next repetition of the same phase, a Lunar month#Synodic month, synodic month, averages about 29.53 days. Therefore, in those lunar calendars in which each month begins on the day of the new moon, the full moon falls on either the 14th or 15th day of the lunar month. Because a calendar month consists of a Natural number, whole number of days, a month in a lunar calendar may be either 29 or 30 days long. Characteristics A full moon is often thought of as an ...
