Who formulated the ideas of fronts and air masses?
Because of the restrictions imposed by the warring nations of Europe during World War I, the meteorologists of neutral Norway were cut off from weather information from outside their country. In response, Norway established its own dense network of weather stations. Led by the father and son team of Vilhem and Jacob Bjerknes, a group of scientists now known as the the Bergen School went to work analyzing the resulting data. From this work they developed the theory of air masses and the weather fronts between air masses. They studied instabilities on the polar front (the boundary between polar and tropical air) and from this developed the basic theory of mid-latitude storms. These theories were to become the very foundations of modern meteorology.
