October 2021 Nor'easter
The October 2021 nor'easter, which eventually became Tropical Storm Wanda, was an erratic nor'easter and tropical cyclone that struck the East Coast of the United States, and meandered across the northern Atlantic Ocean in early November 2021. The powerful extratropical cyclone affected much of the East Coast, causing significant flooding in areas which were previously affected by hurricanes Hurricane Henri, Henri and Hurricane Ida, Ida. As Wanda, the cyclone was the twenty-first and final tropical cyclone of the 2021 Atlantic hurricane season. The system originated from a non-tropical Trough (meteorology), mid-level trough that moved across the Southern United States on October 24–25, and moved out into the Atlantic, where a well defined area of low pressure formed. This quickly became a Explosive cyclogenesis, bomb cyclone off the East Coast of the United States on October 27, causing flooding and bringing powerful gale-force winds to the region in the process. Then, on Octob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtropical Cyclone
A subtropical cyclone is a weather system that has some characteristics of both tropical cyclone, tropical and extratropical cyclones. As early as the 1950s, meteorologists were uncertain whether they should be characterized as Tropical cyclone, tropical or extratropical cyclones. They were officially recognized and titled by the National Hurricane Center in 1972. Beginning in 2002, subtropical cyclones began receiving names from the official tropical cyclone lists in the North Atlantic hurricane, North Atlantic basin. Subtropical cyclones are also recognized in the South-West Indian Ocean tropical cyclone, South-West Indian Ocean and South Atlantic tropical cyclone, South Atlantic basins. There are two definitions currently used for subtropical cyclones depending on their location. Across the north Atlantic and southwest Indian Ocean, they require some central Convectional Precipitation, convection fairly near the center surrounding a warming core existing in the mid-levels of ...

Nantucket
Nantucket () is an island in the state of Massachusetts in the United States, about south of the Cape Cod peninsula. Together with the small islands of Tuckernuck Island, Tuckernuck and Muskeget Island, Muskeget, it constitutes the Town and County of Nantucket, a Consolidated city-county, combined county/town government. Nantucket is the southeasternmost town in both Massachusetts and the New England region. The name "Nantucket" is adapted from similar Eastern Algonquian languages, Algonquian names for the island. Nantucket is a tourism, tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to around 80,000 during the summer months. The average sale price for a single-family home was $2.3 million in the first quarter of 2018. The National Park Service cites Nantucket, designated a National Historic Landmark District in 1966, as being the "finest surviving architectural and environmental example of a late 18th- an ...

Barometric 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 altitudes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosive Cyclogenesis
Explosive cyclogenesis (also referred to as a weather bomb, meteorological bomb, explosive development, bomb cyclone, or bombogenesis) is the rapid deepening of an extratropical cyclonic low-pressure area. The change in pressure needed to classify something as explosive cyclogenesis is latitude dependent. For example, at 60° latitude, explosive cyclogenesis occurs if the central pressure decreases by or more in 24 hours. This is a predominantly maritime, winter event, but also occurs in continental settings. This process is the extratropical equivalent of the tropical rapid deepening. Although their cyclogenesis is entirely different from that of tropical cyclones, bomb cyclones can produce winds of , the same order as the first categories of the Saffir–Simpson scale, and yield heavy precipitation. Even though only a minority of bomb cyclones become this strong, some weaker ones can also cause significant damage. History In the 1940s and 1950s, meteorologists at the Bergen ...

Baroclinity
In fluid dynamics, the baroclinity (often called baroclinicity) of a stratified fluid is a measure of how misaligned the gradient of pressure is from the gradient of density in a fluid. In meteorology, a baroclinic flow is one in which the density depends on both temperature and pressure (the fully general case). A simpler case, barotropic flow, allows for density dependence only on pressure, so that the Curl (mathematics), curl of the pressure-gradient force vanishes. Baroclinity is proportional to: :\nabla p \times \nabla \rho which is proportional to the sine of the angle between surfaces of constant pressure and surfaces of constant density. Thus, in a ''barotropic'' fluid (which is defined by zero baroclinity), these surfaces are parallel. In Earth's atmosphere, barotropic flow is a better approximation in the tropics, where density surfaces and pressure surfaces are both nearly level, whereas in higher latitudes the flow is more baroclinic. These midlatitude belts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Stream
The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude (North Carolina) and moves toward Northwest Europe as the North Atlantic Current. The process of western intensification causes the Gulf Stream to be a northward-accelerating current off the east coast of North America. Around , it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current, recirculating off West Africa. The Gulf Stream influences the climate of the coastal areas of the East Coast of the United States from Florida to southeast Virginia (near 36°N latitude), and to a greater degree, the climate of Northwest Europe. A consensus exists that the climate of Northwest Europe is warmer than other areas of similar latitude at least partially because of the stron ...

Cape Fear (headland)
Cape Fear is a prominent headland jutting into the Atlantic Ocean from Bald Head Island on the coast of North Carolina in the southeastern United States. It is largely formed of barrier beaches and the silty outwash of the Cape Fear River as it drains the southeast coast of North Carolina through an estuary south of Wilmington. Cape Fear is formed by the intersection of two sweeping arcs of shifting, low-lying beach, the result of longshore currents which also form the treacherous, shifting Frying Pan Shoals, part of the Graveyard of the Atlantic. Dunes dominated by sea oats occur from the upper beach drift line back to the stable secondary dunes, where they mix with other grasses such as saltmeadow cordgrass and panic grass, as well as seaside goldenrod, spurge and other herbs to form a stable salt-tolerant grassland. The Cape Fear estuary drains the largest watershed in North Carolina, containing 27% of the state's population. History Giovanni da Verrazzano, the It ...
