polar-front theory

A theory originated by the Scandinavian school of meteorologists whereby a polar front, separating air masses of polar and tropical origin, gives rise to cyclonic disturbances that intensify and travel along the front, passing through various phases of a characteristic life history.

This theory ushered in a new era of atmospheric analysis and remains an important basis of practical synoptic meteorology and weather forecasting even today.
