1856 Last Island Hurricane
The 1856 Last Island hurricane (also known as the Great Storm of 1856) was a deadly and destructive tropical cyclone that is tied with 2020's Hurricane Laura and 2021's Hurricane Ida as the strongest hurricane on record to make landfall in the U.S. state of Louisiana, as measured by maximum sustained winds. The first known tropical cyclone of 1856 Atlantic hurricane season, it was observed first as a minimal hurricane in the Gulf of Mexico near Dry Tortugas on August 9. Moving northwestward, the cyclone quickly intensified into a strong Category 4 hurricane on the modern-day Saffir–Simpson scale by the following day. Late on August 10, the hurricane made landfall on Last Island, Louisiana, with winds at , hours before striking near New Iberia. The system rapidly weakened after moving inland, falling to tropical storm intensity on August 11. The storm would be last noted over Mississippi on the next day. Offshore, at least 183 people drowned after steam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Last Island, Louisiana
Last Island (Official name: Isle Dernière, often misspelled as Îsle Dernière, Isle Dernier, L'Îsle Dernière, Île Dernière, etc.) was a barrier island and location of a pleasure resort southwest of New Orleans on the Gulf Coast of Louisiana, United States. Located south of Dulac, Louisiana, between Lake Pelto, Caillou Bay, and the Gulf of Mexico, it was named Last Island because it was the last of a series of barrier islands which stretched westward from the mouth of the Mississippi River, 90 miles to the east. The island was destroyed by the Last Island Hurricane of August 10, 1856, which split it in two. Afterwards, it became known in the plural Isles Dernières ("Last Islands"). The island was originally approximately 25 miles in length before being split in half by the storm. Subsequent tropical storms did more damage, and Isle Dernière was further fragmented into smaller islands. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Mexico
The Gulf of Mexico () is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the southeast by Cuba. The coastal areas along the Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are occasionally referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific coasts), but more often as "the Gulf Coast". The Gulf of Mexico took shape about 300 million years ago (mya) as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is about wide. Its floor consists of sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Straits of Florida between the ...

National Historic Landmark
A National Historic Landmark (NHL) is a National Register of Historic Places property types, building, district, object, site, or structure that is officially recognized by the Federal government of the United States, United States government for its outstanding historical significance. Only some 2,500, or roughly three percent, of over 90,000 places listed on the country's National Register of Historic Places (NRHP) are recognized as National Historic Landmarks. A National Historic Landmark District may include many contributing properties that are buildings, structures, sites or objects, and it may also include non-contributing properties. Contributing properties may or may not also be separately listed as NHLs or on the NRHP. History The origins of the first National Historic Landmark was a simple cedar post, placed by the Lewis and Clark Expedition on their 1804 outbound trek to the Pacific Ocean in commemoration of the death from natural causes of Sergeant Charles Floyd (e ...

Shadows-on-the-Teche
Shadows-on-the-Teche is an American historic house, garden, and cemetery. Formerly a working sugar cane plantation with enslaved labor, it is located in New Iberia, Louisiana, United States. Built in 1834 for planter, David Weeks (1786–1834) and his wife Mary Conrad Weeks (1797–1863). The property is also home to the Shadows-on-the-Teche cemetery. This is a National Historic Landmark since 1974 and is currently owned and operated by the National Trust for Historic Preservation. House and grounds Architecture Sited 20 feet above the banks of the Bayou Teche, the construction of Shadows-on-the-Teche, a two-and-a-half-story, sixteen room house, coincided with the apogee of the Greek Revival style in United States architecture. When following this style, builders minimized the installation of superfluous decorative elements such as cornices, moldings, and trim. Decorations were severely limited and were designed to blend into and set off the building's handmade red brick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Slavery In Louisiana
Following Robert Cavelier de La Salle establishing the French claim to the territory and the introduction of the name ''Louisiana'', the first settlements in the southernmost portion of Louisiana (New France) were developed at present-day Biloxi (1699), Mobile (1702), Natchitoches (1714), and New Orleans (1718). Slavery was then established by European colonists. The institution was maintained by the Spanish (1763–1800) when the area was part of New Spain, by the French when they briefly reacquired the colony (1800–1803), and by the United States following the Louisiana Purchase of 1803. Due to its complex history, Louisiana had a very different pattern of slavery compared to the rest of the United States. French rule (1699–1763) Slavery was introduced by French colonists in Louisiana in 1706, when they made raids on the Chitimacha settlements. Thousands of indigenous people were killed, and the surviving women and children were taken as slaves. The enslavement of ...

Terrapin
Terrapins are a group of several species of small turtle (order Testudines) living in freshwater, fresh or brackish water. Terrapins do not form a taxonomic unit and may not be closely related. Many belong to the families Geoemydidae and Emydidae. The name "terrapin" is derived from ', a word in an Algonquian languages, Algonquian language"Terrapin" ''www.merriam-webster.com'', accessed 9 November 2021 that referred to the species ''Malaclemys terrapin'' (the diamondback terrapin). It appears that the term became part of common usage during the colonial era of North America and was carried back to Great Britain. Since then, it has been used in common names for freshwater species of Testudines in the English language.Farlex Trivia Dictionary 2012.

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.

Atmospheric Pressure
Atmospheric pressure, also known as air pressure or 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 1,013.25 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 altitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfall (meteorology)
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there.' Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the center of its eye (cyclone), eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding Rain, rains. These coupled with high surf can cause major coastal erosion, beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environ ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is where the barometer reading is lowest. Structure A typical tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Category 5 Atlantic Hurricanes
A Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the Atlantic Ocean to the north of the equator. They are among the strongest tropical cyclones that can form on Earth, having 1-minute sustained wind speeds of at least . The United States National Hurricane Center currently estimates that 11 tropical cyclones between 1851 (the first Atlantic hurricane season to be included in the official Atlantic Atlantic hurricane reanalysis, tropical cyclone record) and 1959 peaked as Category 5 hurricanes. However, because technologies such as satellite imagery, satellite monitoring were not available until the 1960s, some cyclones may have remained undetected. Since 1960, 31 Atlantic hurricanes have reached Category 5. Background Within the Atlantic Ocean to the north of the equator, hurricanes are officially monitored by the United States's National Hurricane Center (NHC), however, other met ...

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 certain distance from the center, known 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 mean sea level, 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 is often used to estimate the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, an ...
