Rossby got his start in meteorology under fluid dynamicist Vilhelm Bjerknes and worked to bring Norwegian methods of air-mass analysis to the US. He soon developed his own school of thought and brought to the study of meteorology and dynamic oceanography novel analysis techniques and influential theories about the behavior of upper-air winds and ocean currents.
