Hilding Köhler
Hilding Köhler (1888–1982) was a professor of meteorology at the Uppsala University, University of Uppsala in Uppsala, Sweden who performed groundbreaking research in cloud physics. In particular, he performed both theoretical and experimental studies on the growth and condensation of water droplets on Cloud condensation nuclei, hygroscopic nuclei. One important and often quoted result of his theoretical research resulted in the well-known Köhler curve. He also made important contributions to theoretical studies on turbulence in the atmosphere. Early life Hilding Köhler was born in Tranemo in 1888, the son of Agnes Hulteni Fredrika Molander and Anders Leonard Köhler. His father was a school-teacher who was born Anders Leonard Johannisson, but changed his name to Köhler when attending the school-teacher seminar. The reason for this change is not known. The family moved to Borås in 1901 so that Hilding could attend the gymnasium there. He finished his studies at the "Latin ...

Köhler Theory
Köhler theory describes the vapor pressure of aqueous aerosol particles in thermodynamic equilibrium with a humid atmosphere. It is used in atmospheric sciences and meteorology to determine the humidity at which a cloud is formed. Köhler theory combines the Kelvin effect, which describes the change in vapor pressure due to a curved surface, with Raoult's Law, which relates the vapor pressure to the solute concentration. It was initially published in 1936 by Hilding Köhler, Professor of Meteorology in the Uppsala University. The Köhler equation relates the saturation ratio S over an aqueous solution droplet of fixed dry mass to its wet diameter D as:S(D)=a_w \exp,with: * S = saturation ratio over the droplet surface defined as S=p_w / p_w^0, where p_w is the water vapor pressure of the solution droplet and p_w^0 is the vapor pressure of pure water with a flat surface * D = diameter of the solution droplet ("wet" diameter) * a_w = water activity of the solution droplet * \sigm ...

Nordstjärneorden
The Royal Order of the Polar Star ( Swedish: ''Kungliga Nordstjärneorden''), sometimes translated as the Royal Order of the North Star, is a Swedish order of chivalry created by King Frederick I on 23 February 1748, together with the Order of the Sword and the Order of the Seraphim. The Order of the Polar Star is intended as a reward for Swedish and foreign "civic merits, for devotion to duty, for science, literary, learned and useful works and for new and beneficial institutions". Its motto is, as seen on the blue enameled centre of the badge, ''Nescit Occasum'', a Latin phrase meaning "It knows no decline". This is to represent that Sweden is as constant as a never setting star. The Order's colour is black. This was chosen so that when wearing the black sash, the white, blue and golden cross would stand out and shine as the light of enlightenment from the black surface. The choice of black for the Order's ribbon may also have been inspired by the black ribbon of the French ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anders Celsius
Anders Celsius (; 27 November 170125 April 1744) was a Swedes, Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 proposed (an inverted form of) the Celsius, Centigrade temperature scale which was later renamed Celsius in his honour. Early life and education Anders Celsius was born in Uppsala, Sweden, on 27 November 1701. His family originated from Ovanåker in the province of Hälsingland. Their family estate was at ''Doma'', also known as ''Höjen'' or ''Högen'' (locally as ''Högen 2''). The name ''Celsius'' is a latinization of the estate's name (Latin 'mound'). As the son of an astronomy professor, Nils Celsius, nephew of botanist Olof Celsius and the grandson of the mathematician Magnus Celsius and the astronomer Anders Spole, Celsius chose a ca ...

Tor Bergeron
Tor Bergeron (15 August 1891 – 13 June 1977) was a Swedish meteorologist who proposed a mechanism for the formation of precipitation in clouds. In the 1930s, Bergeron and developed the concept that clouds contain both supercooled water and ice crystals. According to Bergeron, most precipitation is formed as a consequence of water evaporating from small supercooled droplets and accreting onto ice crystals, which then fall as snow, or melt and fall as cold rain depending on the ambient air temperature. This process is known as the Bergeron Process, and is believed to be the primary process by which precipitation is formed. Bergeron was one of the principal scientists in the Bergen School of Meteorology, which transformed this science by introducing a new conceptual foundation for understanding and predicting weather. While developing innovative methods of forecasting, the Bergen scientists established the notion of weather fronts and elaborated a new model of extratropical cyc ...
