Highest Temperature Recorded On Earth
The highest temperature recorded on Earth has been measured in three major ways: air, ground, and via satellite observation. Air measurements are used as the standard measurement due to persistent issues with unreliable ground and satellite readings. Air measurements are noted by the World Meteorological Organization (WMO) and Guinness World Records among others as the standard to be used for determining the official record. The current official highest registered air temperature on Earth is , recorded on 10 July 1913 at Furnace Creek, California, Furnace Creek Ranch, in Death Valley, Eastern California in the United States. For few years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading. This finding has since raised questions about the legitimacy of the 1913 record measured in Death Valley, with several meteorological experts asserting that there were similar irregularities.

Washington Post
''The Washington Post'', locally known as ''The'' ''Post'' and, informally, ''WaPo'' or ''WP'', is an American daily newspaper published in Washington, D.C., the national capital. It is the most widely circulated newspaper in the Washington metropolitan area and has a national audience. As of 2023, the ''Post'' had 130,000 print subscribers and 2.5 million digital subscribers, both of which were the List of newspapers in the United States, third-largest among U.S. newspapers after ''The New York Times'' and ''The Wall Street Journal''. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. In 1933, financier Eugene Meyer (financier), Eugene Meyer purchased it out of bankruptcy and revived its health and reputation; this work was continued by his successors Katharine Graham, Katharine and Phil Graham, Meyer's daughter and son-in-law, respectively, who bought out several rival publications.

Heat Burst
In meteorology, a heat burst is a rare atmospheric phenomenon characterized by a sudden, localized increase in air temperature near the Earth's surface. Heat bursts typically occur during night-time and are associated with decaying thunderstorms. They are also characterized by extremely dry air and are sometimes associated with very strong, even damaging, winds. Although the phenomenon is not fully understood, the event is thought to occur when rain evaporates ( virga) into a parcel of cold, dry air high in the atmosphere, making the air denser than its surroundings. The parcel descends rapidly, warming due to compression, overshoots its equilibrium level, and reaches the surface, similar to a downburst. Recorded temperatures during heat bursts, as informally known as "Satan's Storm", have reached well above , sometimes rising by or more within only a few minutes. Characteristics In general, heat bursts occur during the late spring and summer seasons. During these times, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snopes
''Snopes'' (), formerly known as the ''Urban Legends Reference Pages'', is a fact-checking website. It has been described as a "well-regarded reference for sorting out myths and rumors" on the Internet. The site has also been seen as a source for both validating and debunking urban legends and similar stories in American popular culture. History 1990s In 1994, David and Barbara Mikkelson created an urban folklore web site that would become ''Snopes.com''. ''Snopes'' was an early online encyclopedia focused on urban legends, which mainly presented search results of user discussions based at first on their contributions to the Usenet newsgroup alt.folklore.urban (AFU) where they'd been active. The site grew to encompass a wide range of subjects and became a resource to which Internet users began submitting pictures and stories of questionable veracity. According to the Mikkelsons, ''Snopes'' predated the search engine concept of fact-checking via search results. David Mik ...

Spontaneous Combustion
Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. It is distinct from (but has similar practical effects to) pyrophoricity, in which a compound needs no self-heat to ignite. The correct storage of spontaneously combustible materials is extremely important, as improper storage is the main cause of spontaneous combustion. Materials such as coal, cotton, hay, and oils should be stored at proper temperatures and moisture levels to prevent spontaneous combustion. Reports of spontaneous human combustion are not considered truly spontaneous, but due to external ignition. Cause and ignition Spontaneous combustion can occur when a substance with a relatively low ignition temperature such as hay, straw, peat, etc., begins to release heat. This may occur in ...

Dasht-e Lut
The Lut Desert, widely referred to as Dasht-e Lut (, "Emptiness Plain"), is a salt desert located in the provinces of Kerman and Sistan-Baluchestan, Iran. It is the world's 33rd-largest desert, and was included in UNESCO's World Heritage List on July 17, 2016. TThe name is derived from ''Lut'' which means 'bare, empty' in Persian and ''dasht'' which means 'plain' in Persian. The surface of its sand has been measured at temperatures as high as 70.7 °C (159.3 °F), the highest-known land surface temperature. Description Iran is climatically part of the Afro-Asian belt of deserts, which stretches from Mauritania all the way to Mongolia. Iran's geography consists of a plateau surrounded by mountains and divided into drainage basins. Dasht-e Lut is one of the largest of these drainage basins, long and wide, The area of the desert is about , the largest in Iran after Dasht-e Kavir.

Aqua (satellite)
Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the Precipitation (meteorology), precipitation, evaporation, and Water cycle, cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (satellite), Terra (launched 1999) and followed by Aura (satellite), Aura (launched 2004). The name "Aqua" comes from the Latin word for water. The satellite was launched from Vandenberg Air Force Base on May 4, 2002, aboard a Delta II Launch vehicle, rocket. Aqua operated in a Sun-synchronous orbit as the third in the satellite formation called the "A-train (satellite constellation), A Train" with several other satellites (OCO-2, the Japanese GCOM, GCOM W1, PARASOL, CALIPSO, CloudSat, and Aura (satellite), Aura) for most of its first 20 years; but in January 2022 Aqua left the A-Train (as Cloud Sat, CALIPSO and PARASOL had already done) when, due to its fuel limitations, it transitioned to a free-drift mode, w ...

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra (EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002. Since 2011, MODIS operations have been supplemented by VIIRS sensors, such as the one aboard Suomi NPP. The systems often conduct similar operations due to their similar designs and orbits (with VIIRS data systems deisgned to be compatible with MODIS), though they have subtle differences contributing to similar but not identical uses. The MODIS instruments were built by Santa Barbara Remote Sensing. They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together the instruments image the entire Earth every 1 to 2 days. They are designed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Conductivity
The thermal conductivity of a material is a measure of its ability to heat conduction, conduct heat. It is commonly denoted by k, \lambda, or \kappa and is measured in W·m−1·K−1. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity. For instance, metals typically have high thermal conductivity and are very efficient at conducting heat, while the opposite is true for insulating materials such as mineral wool or Styrofoam. Metals have this high thermal conductivity due to free electrons facilitating heat transfer. Correspondingly, materials of high thermal conductivity are widely used in heat sink applications, and materials of low thermal conductivity are used as thermal insulation. The reciprocal of thermal conductivity is called thermal resistivity. The defining equation for thermal conductivity is \mathbf = - k \nabla T, where \mathbf is the heat flux, k is the thermal conductivity, and \nabla ...
