Tropical Storm Two (1917)
The 1917 Atlantic hurricane season featured nine known tropical cyclones, four of which became tropical storms. The first system appeared on July 6 east of the Windward Islands. After crossing the islands and traversing the Caribbean Sea, the storm struck Honduras, Belize, and Mexico, before dissipating on July 14. After more than three weeks without tropical cyclogenesis, another tropical storm developed west of Bermuda. As the storm brushed eastern New England, four ships sank near Nantucket, causing 41 fatalities. The same cyclone brought damaging winds to Nova Scotia before transitioning into an extratropical cyclone on August 10. A hurricane developed over the central Atlantic Ocean on August 30 and ultimately affected Bermuda with heightened tides as it passed to the east. Elsewhere, the hurricane had little impact, becoming extratropical on September 5. After the third system, a series of four tropical depressions formed, but failed ...

1917 Nueva Gerona Hurricane
The 1917 Nueva Gerona hurricane was the most intense tropical cyclone to strike the Florida Panhandle until Hurricane Opal in 1995. The eighth tropical cyclone and fourth tropical storm of the season, this system was identified as a tropical storm east of the Lesser Antilles on September 20. After crossing the Lesser Antilles, the system entered the Caribbean Sea and achieved hurricane intensity on September 21. After becoming a Category 2 hurricane, the storm struck the northern coast of Jamaica on September 23. Early on September 25, the cyclone reached Category 4 status and attained maximum sustained winds of soon thereafter. Later that day, the hurricane made landfall in eastern Pinar del Río Province, Cuba. The system entered the Gulf of Mexico shortly thereafter and weakened slightly. Recurving to the northeast, the hurricane briefly threatened Louisiana before turning toward Florida. Early on September 29, the hurricane made landfall near For ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hurricane Research Division
The Hurricane Research Division (HRD) is a section of the Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida, and is the U.S. National Oceanic and Atmospheric Administration's (NOAA) focus for tropical cyclone research. The thirty member division is not a part of the National Hurricane Center but cooperates closely with them in carrying out its annual field program and in transitioning research results into operational tools for hurricane forecasters. HRD was formed from the National Hurricane Research Laboratory in 1984, when it was transferred to AOML and unified with the oceanographic laboratories. In August, 1992, the AOML/HRD facility sustained moderate damage after the passage of Hurricane Andrew across southern Dade County, Florida, however, despite significant personal disruption to the lives of almost all of its staff members, HRD reconnaissance flights continued into Andrew until it made a final landfall along the Louisiana coastline several day ...

Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a metric used by various agencies to express the energy released by a tropical cyclone during its lifetime. It is calculating by summing the square of a tropical cyclone's maximum sustained winds, measured every six hours. The resulting total can be divided by 10,000 to make it more manageable, or added to other totals in order to work out a total for a particular group of storms. The calculation was originally created by William Gray and his associates at Colorado State University as the Hurricane Destruction Potential index, which took the square of each hurricane's maximum sustained winds above every six hours. This index was adjusted by the United States National Oceanic and Atmospheric Administration in 2000 to include all tropical cyclones, with winds above and renamed accumulated cyclone energy. The index has since been used by various other agencies to calculate a storm's accumulated cyclone energy, including the Australian Bureau of ...

United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida Panhandle
The Florida Panhandle (also West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida; it is a Salient (geography), salient roughly long and wide, lying between Alabama on the north and the west, Georgia (U.S. state), Georgia on the north, and the Gulf of Mexico to the south. Its eastern boundary is arbitrarily defined. In terms of population, major communities include Tallahassee, Florida, Tallahassee, Pensacola, Florida, Pensacola, and Panama City, Florida, Panama City. As is the case with the other eight U.S. states that have Salient (geography)#Panhandles in the United States, panhandles, the geographic meaning of the term is inexact and elastic. References to the Florida Panhandle always include the ten List of counties in Florida, counties west of the Apalachicola River, a natural geographic boundary, which was the historic dividing line between the British colonies of West Florida and East Florida. These western counties also lie in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
