1915 Atlantic Hurricane Season
The 1915 Atlantic hurricane season featured the strongest tropical cyclone to make landfall in the United States since the 1900 Galveston hurricane. The first storm, which remained a tropical depression, appeared on April 29 near the Bahamas, while the final system, also a tropical depression, was absorbed by an extratropical cyclone well south of Newfoundland on October 22. Of the six tropical storms, five intensified into a hurricane, of which three further strengthened into a major hurricane. Four of the hurricanes made landfall in the United States. The early 20th century lacked modern forecasting and documentation, and thus, the hurricane database from these years may be incomplete. One of the strongest and most significant storms of the season was the '' Galveston hurricane''. This storm caused devastation across the Greater Antilles, before making landfall in Texas as a Category 4 hurricane on the modern-day Saffir–Simpson scale, the first system to strike ...

1915 New Orleans Hurricane
The New Orleans Hurricane of 1915 was an intense Category 4 hurricane that made landfall near Grand Isle, Louisiana, and the most intense tropical cyclone during the 1915 Atlantic hurricane season. The storm formed in late September when it moved westward and peaked in intensity of 145 mph (230 km/h) to weaken slightly by time of landfall on September 29 with recorded wind speeds of 126 mph (206 km/h) as a strong category 3 Hurricane. The hurricane killed 275 people and caused $13 million (1915 US dollars) in damage. Meteorological history According to the Atlantic hurricane reanalysis project, the 1915 New Orleans hurricane began as a weak tropical storm moving across the southern Windward Islands on September 21, 1915. Its tropical cyclogenesis was determined via analysis of atmospheric observations from the surrounding islands, though shipping in the region would confirm the storm's existence the following day.

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] |
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 ...

1906 Atlantic Hurricane Season
The 1906 Atlantic hurricane season was an average season. It featured twelve tropical cyclones, eleven of which became storms, six became hurricanes and three became major hurricanes. The first storm of the season, a tropical storm in the northern Caribbean, formed on June 8; although it struck the United States, no major impacts were recorded. July saw a period of inactivity, with no known storms. However, in August, the streak of inactivity ended with two storms, including a powerful hurricane. September brought three storms, including a deadly hurricane, with catastrophic impacts in Pensacola and Mobile. October included three storms, with a powerful hurricane that killed over 200 people. The final storm of the season impacted Cuba in early November and dissipated on November 9. The season was quite deadly, with at least with 381 total recorded deaths. __TOC__ Season summary ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns: ...

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 ...

New Decatur, Alabama
Albany, Alabama, also known as New Decatur, Alabama, was a city in Morgan County, Alabama, United States, situated immediately to the southeast of the city of Decatur near the Tennessee River. New Decatur/Albany existed as a city from 1887 until 1927, when it merged with the city of Decatur. Today, it exists as a neighborhood within the city of Decatur, and is on the National Register of Historic Places. History During the American Civil War, the important transportation hub of Decatur, Alabama often changed hands between the Union and the Confederacy. Eventually, the entire city (except for three buildings) fell victim to the war and burned to the ground during the Battle of Decatur. Just as the city was coming back to life, a yellow fever epidemic swept the area in 1878, causing the population of the community to dwindle to approximately 400 by 1880.Historic site marker, Decatur, AL. Retrieved 14-Oct-2008. On January 11, 1887, as Decatur was still rebuilding from the destruct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Decatur Daily
''The Decatur Daily'' is a daily (five days a week) newspaper serving Decatur, Alabama and the Tennessee Valley in the North Alabama area of the United States. As of September 30, 2006, it had an average daily circulation of 20,824 and a Sunday circulation of 23,840. Along with ''The Anniston Star'', it is one of only two family-owned daily newspapers remaining in Alabama. History It was first published on February 26, 1912, under the banner of ''The Decaturs Daily'', serving the towns of Decatur and New Decatur. After 1916, when New Decatur was renamed Albany, the paper was called ''The Albany-Decatur Daily''. When the two towns were consolidated in 1927, it assumed its present title. The newspaper is published by the Tennessee Valley Printing Co., Inc., formed in 1911. William R. Shelton was the primary owner and first publisher.

Atlantic Hurricane Reanalysis Project
The Atlantic hurricane reanalysis project of the National Oceanic and Atmospheric Administration seeks to correct and add new information about past North Atlantic hurricanes. It was started around 2000 to update HURDAT, the official hurricane database for the Atlantic Basin, which has become outdated since its creation due to various systematic errors introduced into the database over time. This effort has involved reanalyses of ship observations from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) as well as reanalyses done by other researchers over the years. It has been ongoing as of 2016, and should last another four years. Inaccuracies and omissions in existing data Errors HURDAT contains a number of errors which need to be corrected, such demonstrated by the outliers in the a pressure vs. wind speed graph of datapoints in the database (right). Some of these errors have existed since the database's creation during NASA's Apollo Program, where it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 760mm Hg, 29.9212 inchesHg, or 14.696psi.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 gravi ...

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 ...

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 ...
