Perlan Project
Perlan Project Inc. is a not-for-profit aeronautical exploration and atmospheric science research organization that utilizes Glider (sailplane), sailplanes (gliders) designed to fly at extremely high altitudes. On 29 August 2006 Steve Fossett and Einar Enevoldson, the pilots of Perlan Mission I, broke the existing altitude record for gliders by soaring up to 50,671 feet (15,460m) in a standard glider using stratospheric waves of air. The Fédération Aéronautique Internationale has ratified the altitude record of achieved on 2 September 2018, a substantial improvement over the previous year's best altitude of , which was set on 3 September 2017. These flights used the custom designed and built pressurized high-altitude Windward Performance Perlan II glider, sponsored by Airbus. They also collected data about Earth's atmosphere and its ozone layer. Meteorological basis of the missions Lee wave, Standing mountain waves are a source of rising air used in the sport of gliding, so ...

Wolf Hirth
Wolfram Kurt Erhard Hirth (28 February 1900 – 25 July 1959) was a German gliding pioneer and sailplane designer. He was a co-founder of Schempp-Hirth, still a renowned glider manufacturer.Segelflugbildkalendar 2011 Hirth was born in Stuttgart, the son of an engineer and tool-maker. He was the younger brother of Hellmuth, who founded the famous Hirth aircraft engine manufacturing company. Early years As a young man, Hirth took up gliding and was soon drawn to the Wasserkuppe, then the focus of the German gliding movement, earning his pilot's licence in 1920. In 1924, Hirth lost a leg after a motorcycle accident. From then on, he would fly while wearing a wooden prosthesis. He had the fibula from his amputated leg fashioned into a cigarette holder In 1928, he graduated from the Technical University of Stuttgart with a diploma in engineering and began to focus on aircraft construction. Over the next decade, he would also tour the world, promoting gliding throughout Europe, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wolfgang Renger
Wolfgang is a German male given name traditionally popular in Germany, Austria and Switzerland. The name is a combination of the Old High German words ''wolf'', meaning "wolf", and ''gang'', meaning "path", "journey", "travel". Besides the regular "wolf", the first element also occurs in Old High German as the combining form "-olf". The earliest reference of the name being used was in the 8th century. The name was also attested as "Vulfgang" in the in the 9th century. The earliest recorded famous bearer of the name was a tenth-century Saint Wolfgang of Regensburg. Due to the lack of conflict with the pagan reference in the name with Catholicism, it is likely a much more ancient name whose meaning had already been lost by the tenth century. Grimm (''Teutonic Mythology'' p. 1093) interpreted the name as that of a hero in front of whom walks the "wolf of victory". A Latin gloss by Arnold of St Emmeram interprets the name as ''Lupambulus''.E. Förstemann, ''Altdeutsches Namenb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiruna, Sweden
(; ; ; ) is the northernmost city in Sweden, situated in the province of Lapland. It had 17,002 inhabitants in 2016 and is the seat of Kiruna Municipality (population: 23,167 in 2016) in Norrbotten County. The city was originally built in the 1890s to serve the Kiruna Mine. The Esrange Space Center was established in Kiruna in the 1960s. Also in Kiruna are the Institute of Space Physics and Luleå University of Technology's Department of Space Science. History Origins Archaeological findings have shown that the region around Kiruna has been inhabited for at least 6,000 years. Centuries before Kiruna was founded in 1900, the presence of iron ore at Kiirunavaara and Luossavaara had been known by the local Sámi population. In 1696, Samuel Mört, a bookkeeper of the Kengis works, wrote on rumours about the presence of iron in the two hills.Kummu 1997, p. 96. The ore became better known after it was reported by Mangi, a Sámi man, in 1736 to Swedish authorities that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tropopause
The tropopause is the atmospheric boundary that demarcates the lowest two layers of the atmosphere of Earth – the troposphere and stratosphere – which occurs approximately above the equatorial regions, and approximately above the polar regions. Definition Rising from the planetary surface of the Earth, the tropopause is the atmospheric level where the air ceases to become cool with increased altitude and becomes dry, devoid of water vapor. The tropopause is the boundary that demarcates the troposphere below from the stratosphere above, and is part of the atmosphere where there occurs an abrupt change in the environmental lapse rate (ELR) of temperature, from a positive rate (of decrease) in the troposphere to a negative rate in the stratosphere. The tropopause is defined as the lowest level at which the lapse rate decreases to 2°C/km or less, provided that the average lapse-rate, between that level and all other higher levels within 2.0 km does not exceed 2°C/km. The trop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Stream
Jet streams are fast flowing, narrow thermal wind, air currents in the Earth's Atmosphere of Earth, atmosphere. The main jet streams are located near the altitude of the tropopause and are westerly winds, flowing west to east around the globe. The northern hemisphere and the southern hemisphere each have a polar jet around their respective polar vortex at around above sea level and typically travelling at around although often considerably faster. Closer to the equator and somewhat higher and somewhat weaker is a subtropical jet. The northern polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica. Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. The El Niño–Southern Oscillation affects the location of the jet s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polar Vortex
A polar vortex, more formally a circumpolar vortex, is a large region of cold, rotating air; polar vortices encircle both of Earth's polar regions. Polar vortices also exist on other rotating, low-obliquity planetary bodies. The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather. The stratospheric polar vortex is an area of high-speed, cyclonically rotating winds around 15 km to 50 km high, poleward of 50°, and is strongest in winter. It forms during autumn when Arctic or Antarctic temperatures cool rapidly as the polar night begins. The increased temperature difference between the pole and the tropics causes strong winds, and the Coriolis effect causes the vortex to spin up. T ...
