Weather reportsIn 1869, Cleveland Abbe began his own private weather reporting and forecasting service at Cincinnati, Ohio, issuing bulletins of his weather reports. On 9 Feb 1870, the U.S. Congress authorized a new federal weather service, under the direction of the Signal Corps. At that time, Abbe was the only person in the nation with experience in gathering telegraphic reports and using them to draw weather maps and make forecasts. Being the obvious choice, Abbe was asked to be the chief scientist inthis new service. He accepted, and on 3 Jan 1871 became the official weather forecaster. As America's first professional meteorologist, Cleveland Abbe is known as the “father of the U.S. Weather Bureau” (later renamed the National Weather Service).« |
