BBC Weather map filled the entire screen, with an off-screen announcer reading the next day's weather. On 11 January 1954, the first in-vision weather forecast was broadcast, presented by George Cowling. In an in-vision the narrator stands in front of the map. At that point, the maps were drawn by hand in the London Weather Centre, before being couriered across London. The forecasts were presented by the same person who had composed them, and had relatively low accuracy. The London Weather Centre which opened in 1959 took the responsibility for the national radio weather broadcasts. Radio forecasters were chosen by a BBC
NACA cowling NACA cowling The NACA cowling is a type of aerodynamic fairing used to streamline radial engines for use on airplanes and developed by the National Advisory Committee for Aeronautics in 1927. It was a major advance in aerodynamic drag reduction, and paid for its development and installation costs many times over due to the gains in fuel efficiency that it enabled. The NACA cowling enhanced speed through drag reduction while delivering improved engine cooling. The idea that the NACA cowling produced thrust through the Meredith effect is fallacious—although in theory the expansion of the air as it was heated by
