Jule Gregory Charney (January 1, 1917 - June 16, 1981) was an American meteorologist who played an important role in developing weather prediction. He developed a set of equations (The Quasi-Geostrophic Vorticity Equation) for calculating the large-scale motions of planetary-scale waves. He gave the first convincing physical explanation for the development of mid-latitude cyclones known as the Baroclinic Instability theory. He is considered the father of modern dynamical meteorology.
