Weather forecasting G. Harold Noyes in 1931. The world's first televised weather forecasts, including the use of weather maps, were experimentally broadcast by the BBC in 1936. This was brought into practice in 1949 after World War II. George Cowling gave the first weather forecast while being televised in front of the map in 1954. In America, experimental television forecasts were made by James C Fidler in Cincinnati in either 1940 or 1947 on the DuMont Television Network. In the late 1970s and early 80s, John Coleman, the first weatherman on ABC-TV's Good Morning America, pioneered the use of on-screen weather satellite
Thomas Cowling they work together. In 1933 Cowling wrote an article, "The magnetic field of sunspots". Joseph Larmor had worked in this area, arguing that sunspots regenerate themselves through a dynamo effect. Cowling showed that Larmor's proposed explanation was incorrect. His article assured him of a good reputation in the field of astrophysics. During the 1930s, Cowling also worked on stellar structure involving radiation and convection, at the same time as Ludwig Biermann but independently of him. He constructed a model of star with a convective core and radiative envelope, named the Cowling model by Chandrasekhar. He also studied magnetic fields within
