The report was given by a cartoon character “Wooly Lamb”. Since hardly anyone owned a television set at that time, only a few could see the report.ĭuring World War II, more information about the jet stream was logged by B-29 pilots. Following the invention of the electronic computer in 1946 (called the ENIAC or Electronic Numerical Integrator And Computer), numerical weather prediction became reality when, in April of 1950, a group of meteorologists at New Jersey’s Institute for Advanced Study successfully produced the first weather forecast using the ENIAC and numerical prediction techniques.Ī New York Times article indicated that the first televised weather report occurred on Octofrom WNBT in New York. Temperature and wind data at different levels of the atmosphere could be combined with the tracking of approaching weather systems. Photo credit: Wikipedia, and is of public domain.ĭuring the 1920’s, forecasting improvements occurred with the launching of weather balloons from various locations around the nation. (KDKA in Pittsburgh, Pennsylvania) was the first to broadcast news and weather information in 1920. The first commercial radio station in the U.S. KDKA broadcast news and weather information that could be heard by the public. was KDKA in Pittsburgh, Pennsylvania, which launched on November 2, 1920.

Also, the mapmaker must take into account that many people have impaired color vision, and colors must be used such that these readers can see their differences.The evolution of broadcast meteorology has worked hand in hand with advances in technology.

Typical uses of color include showing different countries, different temperatures, or different kinds of roads.ĭisplaying the information in different colors can affect the understanding or feel of the map.

Examples of this are coloring that show the countries or divisions of a country, but also to visualize other data, for example the altitude.
