"Over the past 100 years, the international science community including government weather services, the proliferation of environmental observations, improved scientific understanding, growth of technology, and the media have together radically transformed weather forecasting into an effective, global and regional environmental prediction capability," write researchers commemorating the centennial of the American Meteorological Society's establishment. They trace the "evolution of forecasting starting in 1919 over four eras separated by breakpoints at 1939, 1956, and 1985. The current state of forecasting could not have been achieved without essential collaboration within and among countries in pursuing the common weather and earth-system prediction challenge."
MIT played a significant role in pushing the fields of meteorology, weather forecasting and climate research and training forward. Carl-Gustaf Rossby, Jule Charney, Edward Lorenz, Sverre Petterssen, and Norman Phillips were a handful of personalities who laid the foundations for forecasting today.
