The "Bergen School of Meteorology" is a school of thought which is the basis for much of modern weather forecasting.

Founded by the meteorologist Prof. Vilhelm Bjerknes and his younger co-workers, the Bergen School attempts to define the motion of the atmosphere by means of the mathematics of interactions between hydro- and thermodynamics, some of which had originally been discovered or explained by Bjerknes himself, thus making mathematical predictions regarding the weather possible by systematic data analysis.
