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. [ 1 ] [ 2 ] [ 3 ] It was initially published in 1936 by Hilding Köhler , Professor of Meteorology in the Uppsala University.
the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles
Hilding Köhler (1888–1982) was a professor of meteorology at the University of Uppsala in Uppsala, Sweden [1] 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 hygroscopic nuclei. [ 2 ]
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
Köhler theory, describes the process in which water vapor condenses and forms liquid cloud drops; Köhler disease, a rare bone disorder of the foot found in children between six and nine years of age. The disease typically affects boys, but it can also affect girls. It was first described in 1908 by Alban Köhler (1874–1947), a German ...

Luke Howard FRS (28 November 1772 – 21 March 1864) was a British manufacturing chemist and an amateur meteorologist with broad interests in science. [1] His lasting contribution to science is a nomenclature system for clouds, which he proposed in an 1802 presentation to the Askesian Society.
