The team studied events in or near Australia, Brazil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Scientist
Atmospheric science is the study of the Earth's atmosphere and its various inner-working physical processes. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology is the study of atmospheric changes (both long and short-term) that define average climates and their change over time, due to both natural and anthropogenic climate variability. Aeronomy is the study of the upper layers of the atmosphere, where dissociation and ionization are important. Atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets and natural satellites of the Solar System. Experimental instruments used in atmospheric science include satellites, rocketsondes, radiosondes, weather balloons, radars, and lasers. The term aerology (from Greek ἀήρ, ''aēr'', " air"; and -λογία, '' -logia'') is sometimes used as an alternative term for the study of Earth's atmosphere; i ...

Wind
Wind is the natural movement of air or other gases relative to a planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption of solar energy between the climate zones on Earth. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet ( Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their spatial scale, their speed and direction, the forces that cause them, the regions in which they occur, and their effect. Winds have va ...

North Dakota
North Dakota () is a U.S. state in the Upper Midwest, named after the indigenous Dakota Sioux. North Dakota is bordered by the Canadian provinces of Saskatchewan and Manitoba to the north and by the U.S. states of Minnesota to the east, South Dakota to the south, and Montana to the west. It is believed to host the geographic center of North America, Rugby, and is home to the tallest man-made structure in the Western Hemisphere, the KVLY-TV mast. North Dakota is the 19th largest state, but with a population of less than 780,000 as of 2020, it is the 4th least populous and 4th most sparsely populated. The capital is Bismarck while the largest city is Fargo, which accounts for nearly a fifth of the state's population; both cities are among the fastest-growing in the U.S., although half of all residents live in rural areas. The state is part of the Great Plains region, with broad prairies, steppe, temperate savanna, badlands, and farmland being defining characteris ...

Trail Of Tears
The Trail of Tears was an ethnic cleansing and forced displacement of approximately 60,000 people of the "Five Civilized Tribes" between 1830 and 1850 by the United States government. As part of the Indian removal, members of the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations were forcibly removed from their ancestral homelands in the Southeastern United States to newly designated Indian Territory west of the Mississippi River after the passage of the Indian Removal Act in 1830. The Cherokee removal in 1838 (the last forced removal east of the Mississippi) was brought on by the discovery of gold near Dahlonega, Georgia, in 1828, resulting in the Georgia Gold Rush. The relocated peoples suffered from exposure, disease, and starvation while en route to their newly designated Indian reserve. Thousands died from disease before reaching their destinations or shortly after. Some historians have said that the event constituted a genocide, although this lab ...

Cherokee Nation
The Cherokee Nation (Cherokee: ᏣᎳᎩᎯ ᎠᏰᎵ ''Tsalagihi Ayeli'' or ᏣᎳᎩᏰᎵ ''Tsalagiyehli''), also known as the Cherokee Nation of Oklahoma, is the largest of three Cherokee federally recognized tribes in the United States. It was established in the 20th century and includes people descended from members of the Old Cherokee Nation who relocated, due to increasing pressure, from the Southeast to Indian Territory and Cherokee who were forced to relocate on the Trail of Tears. The tribe also includes descendants of Cherokee Freedmen, Absentee Shawnee, and Natchez Nation. As of 2021, over 400,000 people were enrolled in the Cherokee Nation. Headquartered in Tahlequah, Oklahoma, the Cherokee Nation has a reservation spanning 14 counties in the northeastern corner of Oklahoma. These are Adair, Cherokee, Craig, Delaware, Mayes, McIntosh, Muskogee, Nowata, Ottawa, Rogers, Sequoyah, Tulsa, Wagoner, and Washington counties. History Late 18th century through ...

John Ross (Cherokee Chief)
John Ross ( chr, ᎫᏫᏍᎫᏫ, translit=guwisguwi) (October 3, 1790 – August 1, 1866), (meaning in Cherokee: "Mysterious Little White Bird"), was the Principal Chief of the Cherokee Nation from 1828 to 1866; he served longer in that position than any other person. Described as the Moses of his people, Ross influenced the nation through such tumultuous events as the relocation to Indian Territory and the American Civil War. Ross was the son of a Cherokee mother and a Scottish father. His mother and maternal grandmother were each of mixed Scots-Cherokee ancestry but brought up in Cherokee culture, which is matrilineal. His maternal grandfather was a Scottish immigrant. At the time among the matrilineal Cherokee, children born to a Cherokee mother were considered part of her family and clan; they gained their social status from their mother. The Cherokee absorbed mixed-race descendants born to its women. As a result, young John was raised to identify as Cherokee, while also le ...

Hurricane
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling rou ...

Electric Field
An electric field (sometimes E-field) is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to the physical field for a system of charged particles. Electric fields originate from electric charges and time-varying electric currents. Electric fields and magnetic fields are both manifestations of the electromagnetic field, one of the four fundamental interactions (also called forces) of nature. Electric fields are important in many areas of physics, and are exploited in electrical technology. In atomic physics and chemistry, for instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also the force responsible for chemical bonding between atoms that result in molecules. The electric field is defined as a vector field that associates to each point in space the electrostatic (Coulomb) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lightning
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily neutralize themselves, causing the instantaneous release of an average of one gigajoule of energy. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. The three main kinds of lightning are distinguished by where they occur: either inside a single thundercloud (intra-cloud), between two clouds (cloud-to-cloud), or between a cloud and the ground ...
