2020 Easter Tornado Outbreak
A widespread and deadly tornado outbreak affected the Southeastern United States on Easter Sunday and Monday, April 12–13, 2020. Several tornadoes were responsible for prompting tornado emergency, tornado emergencies, including the first one to be issued by the National Weather Service in Charleston, South Carolina. A large squall line formed and tracked through the Mid-Atlantic (United States), mid-Atlantic on April 13, prompting more tornado warnings and Tornado watch, watches. A total of 15 watches were produced during the course of the event, two of which were designated Particularly Dangerous Situations. Throughout the two-day outbreak, a total of 141 tornadoes touched down across 10 states, inflicting widespread and locally catastrophic damage. The outbreak ranks 4th for producing the most tornadoes in a 24-hour period, with 132 tornadoes occurring between 14:40 UTC April 12–13; that tally is surpassed only by the Tornado outbreak of March 31 – April 1, 2023 ...

Tornadoes Of 2020
This page documents notable tornadoes and tornado outbreaks worldwide in 2020. Strong and destructive tornadoes form most frequently in the United States, Argentina, Brazil, Bangladesh, and East India, eastern India, but can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, Argentina, Australia and New Zealand. Tornadic events are often accompanied by other forms of severe weather, including strong thunderstorms, strong winds, and hail. There were 1,243 preliminary filtered reported tornadoes in 2020 in the United States in 2020, and 1,086 confirmed tornadoes in the United States in 2020. Worldwide, at least 93 tornado-related deaths were confirmed with 78 in the United States, eight in Vietnam, two each in Canada, Indonesia, and Mexico, and one in South Africa. It was the deadliest year of tornadoes in the Unite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Storm Prediction Center
The Storm Prediction Center (SPC) is a US government agency that is part of the National Centers for Environmental Prediction (NCEP), operating under the control of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the United States Department of Commerce (DoC). Headquartered at the National Weather Center in Norman, Oklahoma, the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues #Convective outlooks, convective outlooks, #Mesoscale discussions, mesoscale discussions, and #Weather watches, watches as a part of this process. Convective outlooks are issued for the following eight days (issued separately for Day 1, Day 2, Day 3, and Days 4–8), and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Days 1 an ...

Tornado Watch
A tornado watch ( SAME code: TOA) is a statement issued by weather forecasting agencies to advise the public that atmospheric conditions in a given region may lead to the development of tornadoes within (or near) the region over a period of several hours. In addition to the potential for tornado development, thunderstorms that develop within the watch area may contain large hail, straight-line winds, intense rainfall and/or flooding that pose a similar damage risk as the attendant tornado threat. A watch must not be confused with a tornado warning, and encourages the public to remain vigilant for the onset of severe weather, including possible tornadoes. A tornado watch does not mean a tornado has been observed or ''will'' occur, just that favorable conditions increase the likelihood of such storms happening, and may be issued several hours ahead of the formation or arrival of potentially tornadic thunderstorms. Definition A ''tornado watch'' indicates that atmospheric condit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Edwards Plateau
The Edwards Plateau is a geographic region forming the crossroads of Central, South and West Texas, United States. It is named in honor of Haden Edwards. It is bounded by the Balcones Fault to the south and east; the Llano Uplift and the Llano Estacado to the north; and the Pecos River and Chihuahuan Desert to the west. San Angelo, Austin, San Antonio and Del Rio roughly outline the area. The plateau, especially its southeast portion, is also known as the Texas Hill Country. Natural history The bedrock consists primarily of limestone, with elevations ranging between 100 and 3000 ft. Caves are numerous. The landscape of the plateau is mostly savanna scattered with trees. It mostly lacks deep soil suitable for farming, though the soil type is fertile mollisol, so some cotton, grain sorghum, and oats are grown. For the most part, though, the thin soil and rough terrain areas are primarily grazing regions, with cattle, sheep, and goats ( Angora and meat types) predom ...

Shortwave (meteorology)
A shortwave or shortwave trough is an embedded kink in the trough / ridge pattern. Its length scale is much smaller than that of and is embedded within longwaves, which are responsible for the largest scale (synoptic scale) weather systems. Shortwaves may be contained within or found ahead of longwaves and range from the mesoscale to the synoptic scale. Shortwaves are most frequently caused by either a cold pool or an upper level front. Shortwaves are commonly referred to as a vorticity maximum. Corresponding weather and effects Shortwaves are often associated with warm air advection (WAA) or cold air advection (CAA), which influence temperature. Due to the way they move the air around them and the way air moves away from them, shortwaves produce positive curvature vorticity and positive shear vorticity, respectively. Ahead of a shortwave there is large-scale lift due to divergence from positive vorticity advection (PVA). This lift often causes precipitation. In a capp ...

Florida Panhandle
The Florida panhandle (also known as West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida. It is a Salient (geography), salient roughly long, bordered by Alabama on the west and north, Georgia (U.S. state), Georgia on the north, and the Gulf of Mexico to the south. Its eastern boundary is arbitrarily defined. It is defined by its Culture of the Southern United States, southern culture and Rural area, rural demographics in contrast to urbanized central and southern Florida, as well as closer cultural links to Alabama and Georgia. Its major communities include Pensacola, Florida, Pensacola, Navarre, Florida, Navarre, Destin, Florida, Destin, Panama City Beach, Florida, Panama City Beach, and Tallahassee, Florida, Tallahassee. 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.

Ridge (meteorology)
In meteorology a ridge or barometric ridge is an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar regions and bri ...

Southeast US Severe Weather Outbreak 2020-04-12 2156z
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A ''compass rose'' is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 "points" (and any finer subdivisions are described in fractions of points). Compass points or compass directions are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal direction ...

COVID-19 Pandemic In The United States
On December 31, 2019, China announced the discovery of a cluster of pneumonia cases in Wuhan. The first American case was reported on January 20, and United States Department of Health and Human Services, Health and Human Services Secretary Alex Azar declared a Public health emergency (United States), public health emergency on January 31. Restrictions were placed on flights arriving from China, but the initial U.S. response to the pandemic was otherwise slow in terms of preparing the healthcare system, stopping other travel, and COVID-19 testing in the United States, testing. The first known American deaths occurred in February and in late February President Donald Trump proposed allocating $2.5 billion to fight the outbreak. Instead, Congress approved $8.3 billion and Trump signed the Coronavirus Preparedness and Response Supplemental Appropriations Act, 2020 on March 6. Trump declared a State of emergency, national emergency on March 13. The government also purchased lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
State Of Emergency
A state of emergency is a situation in which a government is empowered to put through policies that it would normally not be permitted to do, for the safety and protection of its citizens. A government can declare such a state before, during, or after a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. Relationship with international law Under international law, rights and freedoms may be suspended during a state of emergency, depending on the severity of the emergency and a government's policies. Use and viewpoints Democracies use states of emergency to manage a range of situations from extreme weather events to public order situations. dictatorship, Dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of time so that derogations can be used to override human rights of their citizens usually protected by the International Covenant on Civi ...

Tornado Outbreak Of April 27–30, 2014
A tornado is a violently rotating column of air that is in contact with the surface of Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the Earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Tornadoes come in many shapes and sizes, and they are often (but not always) visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than , are about across, and travel several kilometers (a few miles) before dissipating. The most extreme tornadoes can attain wind speeds of more than , can be more than in diameter, and can stay on the grou ...
