Richard Assmann
Richard Assmann (Anglicized spelling of the German name Richard Aßmann) (13 April 1845 in Magdeburg – 28 May 1918 in Gießen) was a German meteorologist and physician who was a native of Magdeburg. He made numerous contributions in high altitude research of the Earth's atmosphere. He was a pioneer of scientific aeronautics and considered a co-founder of aerology.Magdeburger Biographischen Lexikon (biography) In 1868 he received his medical doctorate in , and from 1870 to 1879 was a general practitioner in |
Arthur Berson
Arthur Josef Stanislaus Berson (6 August 1859 – 3 December 1942) was a German meteorologist and pioneer of aerology who was a native of Neu Sandez, Galicia (now Nowy Sącz, Poland). After visiting the gymnasium in Neu Sandez, Berson studied philology in Vienna. He then studied meteorology and geography in Berlin, where he had as instructors Ferdinand von Richthofen and Wilhelm von Bezold. In 1890 he was an assistant to meteorologist Richard Aßmann at the Meteorological Institute in Berlin. During this period of time he was also secretary of the ''Deutschen Verein zur Förderung der Luftschiffahrt'', the first aeronautical organization in Germany. In 1900 he became ''Hauptobservator'' at the newly founded Aeronautics Observatory in Berlin-Tegel, and was later stationed at the Lindenberg Aeronautical Observatory in Beeskow. From 1896 to 1899 Berson was editor of the magazine ''Zeitschrift für Luftfahrt und Physik der Atmosphäre'' (Magazine for Aviation and Physics of ...

Psychrometer
A hair tension dial hygrometer with a nonlinear scale. A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use the temperature of condensation (called the dew point), or they sense changes in electrical capacitance or resistance to measure humidity differences. A crude hygrometer was invented by Leonardo da Vinci in 1480. Major leaps came forward during the 1600s; Francesco Folli invented a more practical version of the device, while Robert Hooke improved a number of meteorological devices including the hygrometer. A more modern version was created by Swiss polymath Johann Heinrich Lambert in 1755. Later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Current
In meteorology, air currents are concentrated areas of winds. They are mainly due to differences in atmospheric pressure or temperature. They are divided into horizontal and vertical currents; both are present at mesoscale while horizontal ones dominate at synoptic scale. Air currents are not only found in the troposphere, but extend to the stratosphere and mesosphere. Horizontal currents A difference in air pressure causes an air displacement and generates the wind. The Coriolis Force deflects the air movement to the right in the northern hemisphere and the left in the southern one, which makes the winds parallel to the isobars on an elevation in pressure card. It's called the geostrophic wind. Pressure differences depend, in turn, on the average temperature in the air column. As the sun does not heat the Earth evenly, there is a temperature difference between the poles and the equator, creating air masses with more or less homogeneous temperature with latitude. Differences ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Germany (geography)
Central Germany (''Zentraldeutschland''/''Mitteldeutschland''), in geography, describes the areas surrounding the geographical centre of Germany. Hesse, Saxony-Anhalt and Thuringia are the only landlocked German states without an international border except for the city-states of Berlin and Hamburg. Geographical centre The central point shifted several times during the country's eventful history. Today Niederdorla in the state of Thuringia claims to be the most central municipality in Germany. A plaque was erected and a lime tree planted at after the 1990 German reunification. Niederdorla, German Wikipedia Retrieved 1 Nov 2011 The point was confirmed as the centroid of the extreme coordinates by the Dresden University of Technology. Niederdorla also comprises the centre of gravity (equilibrium point) about to the southwest. Other municipalities competing are Krebeck in Lower Saxony and Edermünde in Hesse, as well as the village of Landstreit near Eisenach. The geographical ...

Léon Teisserenc De Bort
Léon Philippe Teisserenc de Bort (5 November 1855 in Paris, France – 2 January 1913 in Cannes, France) was a French meteorologist and a pioneer in the field of aerology. Together with Richard Assmann (1845-1918), he is credited as co-discoverer of the stratosphere, as both men announced their discovery during the same time period in 1902. Teisserenc de Bort pioneered the use of unmanned instrumented balloons and was the first to identify the region in the atmosphere around 8-17 kilometers of height where the lapse rate reaches zero, known today as the tropopause. Early life and career He was the son of an engineer. He began his scientific career in 1880, when he entered the meteorological department of the Bureau Central Météorologique (Administrative Centre of National Meteorology, a department of the French government) in Paris under E. E. N. Mascart. In 1883, 1885 and 1887 he made journeys to North Africa to study geology and terrestrial magnetism, and during this period ...
