The purpose of this paper is to assemble facts relating to the history, progress, and present usage of radio in relation to the work of the weather Bureau. The Weather Bureau was the pioneer of all agencies of the United States Government in investigations and experiments in wireless telegraphy. The investigations were undertaken because it was foreseen that this form of communication presented a field of opportunity to meteorology in securing current weather information from inaccessible places and ships, the providing of storm warnings to vessels at sea, and supplementing or replacing the Weather Bureau system of collecting weather reports by telegraph and cable.

Radio has been utilized continuously by the Weather Bureau for more than 20 years, and it now plays a large and indispensable part in its activities.
