BIOGRAPHICAL MEMOIRS National Academy of Sciences Jacob Aall Bonnevie Bjerknes By Arnt Eliassen JACOB AALL BONNEVIE BJERKNES, or Jack Bjerknes as he was usually called, was one of the founders of modern meteorology. He entered the scientific scene at the age of twenty with the discovery of the structure of extratropical cyclones, which became of the greatest importance and formed the starting point of a fruitful development for theoretical meteorology as well as practical weather forecasting. It was Jack's father, the famous physicist and geophysicist Vilhelm Bjerknes, who set the stage for the research leading up to this discovery, but Jack was the principal performer. FAMILY BACKGROUND The name Bjerknes comes from a family farm in southeastern Norway where some of Jack's ancestors lived. Jack represented the third generation in a dynasty of scientists. His grandfather, Carl Anton Bjerknes, was professor of mathematics at the University of Christiania, as the Norwegian capital Oslo was called at the time. He showed both theoretically and by experiment that an ideal fluid would transfer Coulomb-type forces between pulsating spheres and thought that he was on the track of a hydrodynamical ether theory of electromagnetism. Jack's father, Vilhelm Bjerknes, began his career as a physicist working with Heinrich Hertz in Bonn on electromagnetic resonance. In 1893 he married Honoria Sophia Bonnevie, a Norwegian science student in Christiania. They settled in Stockholm, where Vilhelm Bjerknes was appointed lecturer and later professor of mechanics and mathematical physics.

Die Geschichte der meteorologischen Forschung in Leipzig läßt sich fast 5 Jahrhunderte zurückverfolgen. 1507 wurde hier Virgil Wellendarffers Decalogium gedruckt, das häufig als erstes Lehrbuch der Meteorologie bezeichnet wird. Aus dem 17. und 18. Jahrhundert liegen mehrere, meist aber nur über kurze Zeiträume durchgeführte meteorologische Beobachtungen vor. So hat z.B. der bekannte "Bauernastronom" Christoph Arnold in Sommerfeld bei Leipzig von 1688 bis 1695 Wetteraufzeichnungen vorgenommen. Der Mechaniker Jacob Leupold (1674-1727) entwickelte Regenmesser sowie andere meteorologische Meßgeräte und schrieb Anweisungen zu deren Gebrauch. Von einem namentlich nicht bekannten Leipziger wurden von 1759 bis 1794 instrumentelle Wetterbeobachtungen vorgenommen Brandes' Wetterkarte von 1826 Carl Friedrich Naumann Carl Christian Bruhns Das "Meteorologische Bureau für Wetterprognosen" in der Leipziger Innenstadt (im 2. Weltkrieg zerstört) Die Entwicklung der Luftfahrt um 1900 veranlassten den Physiker Otto Wiener und den Astronomen Heinrich Bruns (Nachfolger von Carl Christian Bruhns), sich energisch für die Schaffung eines geophysikalischen Instituts an der Universität Leipzig einzusetzen. Von Anfang an dachte man bei der Besetzung des Lehrstuhls für Geophysik - neben dem später durch die Kontinentalverschiebungstheorie bekannt gewordenen Alfred Wegener - an den Norweger Vilhelm Bjerknes (1862-1951), "als der Hervorragendste der ganzen Welt auf dem Gebiete der dynamischen Meteorologie". Geradezu prophetisch meinte Wiener in seinem Gutachten: "An die richtige Stelle gesetzt, würde er eine neue Epoche der Meteorologie herbeiführen".

JACOB BJERKNES (1897-1975) Jacob Aall Bonnevie Bjerknes was born in Stockholm, Sweden, in 1897. He continued a legacy of hydrodynamic application theory that began with his physics professor grandfather Carl and was extended by Jacob's father, the theoretical physicist Vilhelm Bjerknes. From 1914 to 1916, Bjerknes attended the University of Kristiania (Oslo), where he became interested in his father's work relating hydrodynamic theory to atmospheric motion and weather prediction. Jacob followed his father and his group of young Norwegian meteorologists to the University of Leipzig, where their research focused on the formation of heavy precipitation along ordered cloud boundaries then called "squall lines." Through surface map analysis, Jacob discovered that these boundaries coincided with the convergence of wind fields, making the latter a potential detector and predictor of weather patterns. In 1926, Jacob served as a support meteorologist for Roald Amundsen's polar dirigible flight. In 1928 he married Hedvig Borthen. In 1931, he left his position as head of the weather service at Bergen to become professor of meteorology at the geophysical institute his father had founded. By 1933 he discovered yet another aspect of the cyclone phenomenon, the upper atmospheric wave. His preliminary formulation of the use of pressure tendency as a surface indication of cyclone development appeared in 1937. Jacob lectured at the Massachusetts Institute of Technology during the 1933-1934 school year and emigrated to the United States in 1940 where he headed a government-sponsored meteorology annex, for weather forecasting, to the department of physics at the University of California, Los Angeles (UCLA). That same year of 1940 saw the invasion of Norway by Germany and Bjerknes' receipt of the Symons Medal from the Royal Meteorological Society. At UCLA, Bjerknes and fellow Norwegian Jorgen Holmboe further developed the pressure tendency and the extratropical cyclone theories.

Trabajó como investigador en el Instituto Carnegie de Washington (1906-36). Hacia 1918 revolucionó la ciencia de la meteorología con su teoría de las masas de aire, a la que la aviación comercial debe algunos de sus primeros grandes avances. Su hijo Jacob (1897-1975), también meteorólogo y profesor en la Universidad de California, descubrió el desarrollo de los ciclones, paso importante en la predicción del tiempo.
