branch of science that deals with the atmosphere of a planet, particularly that of the earth, the most important application of which is the analysis and prediction of weather.

. He worked on applying hydrodynamic and thermodynamic theories to atmospheric and hydrospheric conditions in order to predict future weather conditions. Bjerknes was professor at the universities of Oslo (1907–12, 1926–32); Leipzig (1912–17); and Bergen (1917–26), where he set up a geophysical institute. His work in meteorology and on electric waves was important in the early development of wireless telegraphy. His publications include Fields of Force (1906) and the classic book On the Dynamics of the Circular Vortex with Applications to the Atmosphere and to Atmospheric Vortex and Wave Motion (1921); he is also coauthor with J. W. Sandström (on Vol. I) and with T. Hesselberg and O. Devik (on Vol. II) of Dynamic Meteorology and Hydrography (Vol. I and II, 1910–11; Vol. III, 1951). He evolved a theory of cyclones known as the polar front theory with his son Jakob Aall Bonnevie Bjerknes, 1897–1975, who became a U.S. citizen in 1946. Jakob Bjerknes served as professor of meteorology at the Univ. of Bergen (1931–40) and at the Univ. of California (from 1940).

Bjerknes, Vilhelm Frimann Koren

 

Born Mar. 14, 1862, in Christiania, now Oslo; died there Apr. 9, 1951. Norwegian physicist and geophysicist.

Bjerknes was a professor at the Bergen Geophysical Institute (1917-26) and the universities of Oslo (1926-32) and Stockholm (after 1895). Bjerknes was responsible for studies of electrical resonance, under the direction of H. Hertz (1890-91), which were very important for the development of the radio. Bjerknes proved a theorem about the circulation rate of fluids and, with its help, explained the origin of marine currents and winds. He developed dynamic methods of weather forecasting and founded the weather service in Norway (1917).

Along the way, there are glimpses into the scientific hinterland: the obstacles to female involvement (Vilhelm Bjerknes' wife Honoria, the first female maths student at Kristiana University, 'was never able to pursue her interest in numbers and geometry other than through embroidery'), and the rivalry between practitioners--returning from a conference, Bjerknes wrote of an Asian scientist that 'the turban and the oriental eloquence have been good cards in his hand'.
El Nino is part of the world's most significant climate process referred to as ENSO (see Ribbe (2002) for further descriptions of the typical characteristics of this feature) and Bjerknes (1969) was the first to provide a full description.
