Bjerknes, Vilhelm Firman Koren Norwegian scientist whose theory of polar fronts formed the basis of all modern weather forecasting and meteorological studies. He also developed hydrodynamic models of the oceans and the atmosphere and showed how weather prediction could be carried out on a statistical basis, dependent on the use of mathematical models. Bjerknes was professor at Stockholm, Sweden, and Leipzig, Germany, before returning to Norway and founding the Bergen Geophysical Institute 1917. During World War I, Bjerknes instituted a network of weather stations throughout Norway; coordination of the findings from such stations led him and his co-workers to the theory of polar fronts, based on the discovery that the atmosphere is made up of discrete air masses displaying dissimilar features. He coined the word 'front' to denote the boundary between such air masses.

window.name = "_root" Bjerknes (Vilhelm) Géophysicien norvégien (1862-1951). Mathématicien et physicien de formation, il ne tarda pas à s'intéresser aux applications de l'hydrodynamique à la météorologie et à l'océanographie ; l' atmosphère étant un fluide, la prévision du temps , en vint-il à penser, constituait un problème dont la formulation était de nature mathématique et dont la résolution dépendait de conditions bien déterminées (voir l' encart Dans les années 1907 à 1910, Vilhelm Bjerknes établit avec Johan Wilhelm Sandström qu'il était préférable d'analyser et prévoir l'atmosphère sur des surfaces isobares plutôt que sur des surfaces à altitude constante ; tous deux démontrèrent des théorèmes fondamentaux concernant la circulation atmosphérique. Après un séjour en Allemagne, entre 1913 et 1917, en qualité de Directeur du Nouvel Institut de Géophysique de Leipzig, Bjerknes revint en Norvège et fonda à l'université de Bergen, en 1917, un Institut de géophysique ; il y regroupa d'éminents météorologistes, parmi lesquels Holvar Solberg, Tor Bergeron , plus tard Ragnar Fjörtoft, et également son propre fils

European Geophysical Society Vilhelm Bjerknes The Section on Oceans and Atmosphere has established a new medal for distinguished research in atmospheric sciences. The medal is named after Vilhelm Bjerknes (1862-1951), one of the leading atmospheric scientists of the first half of this century. In the following there is a summary provided by Arnt Eliassen, Honorary Member of the EGS: In a programmatic paper from 1904 he proposed the procedure Which is now called numerical weather prediction. He advocated that weather prognosis should be considered as an initial value problem of mathematical physics, and carried out by integrating the governing equations forward in time, starting from the observed atmospheric state. The problems of analysis were further studied during Bjerknes's stay in Oslo and Leipzig. In 1917 Bjerknes settled in Bergen with two research assistants, his son Jack and Jack's fellow student Halvor Solberg; they were later joined by the Swedish meteorologist Tor Bergeron. This team put forward the polar front theory of cyclones, which has for 75 years served as an effective tool in weather analysis and forecasting. Vilhelm Bjerknes had a rare ability to attract and inspire gifted students. He promoted progress in his field not only through his own work, but also by recruiting into geophysics a considerable number of students who later became prominent meteorologists or oceanographers. He was also efficient in making his and his co-worker's achievements known, not only to the scientific community, but to politicians and the public as well.

VILHELM BJERKNES Sin lugar a equivocarnos, podemos decir que Vilhelm Bjerhnes y su hijo Jacob son dos de los grandes nombre de la meteorología moderna. Su aporte al entendimiento atmosférico es la piedra angular de los conocimientos que forman parte del diseño de los poderosos modelos meteorológicos actuales. BIOGRAFIA GENERAL Vilhelm Bjerknes nació en Noruega en 1862. Luego de terminada su formación profesional, colabora con su padre en algunas investigaciones, pero finalmente su vida continúa en otro pais: Alemania. Ya en Alemania, Bjerknes trabaja junto a Rudolf Hertz, y participa de sus estudios sobre resonancia eléctrica, y la radiación descubierta por el físico alemán. Luego se radica en Suecia, dedicando su tiempo a estudiar termodinámica e hidrodinámica relacionandolas con el movimiento de las masas de aire. Sus concluisiones llevan a los dos importantes principios que lo inmortalizan en el mundo de la meteorología. Fundamentalmente, su aporte apunta a indicar claramente que la conjunción del calentamiento solar y el movimiento terrestre (que genera rozamiento) son protagonistas de la dinámica atmosférica. Su primer principio es de múltiples aplicaciones en meteorología. Indica que si los gradientes de presión y de temperatura tienen direcciones distintas, "se crea energía" que fuerza al aire a circular en el sentido que lleva desde el extremo del vector gradiente de presión (direccion en la que aumenta la presión) al del vector gradiente de temperatura (direccion en la que aumenta la temperatura) por el camino más corto".
