Weather Predictions The Weather Bureau Research Station was started in 1956 to study intensively the meterology of the Nevada TestSite. In late 1957 the station became responsible for providing meterological support for nuclear weaponstests. Prior to these dates this function was performed by the Air Weather Service of the U.S. Air Force. The Weather Bureaustation at the Nevada Test Site received all of the atmospheric sounding information taken every six hours by the stations shown on the map (fig. 11), and most of the hourly and six-hourly weather information produced in the entire United States, Canada, Mexico and eastern Pacific Ocean. In addition, there were and are some 26 wind, 20 temperature, and 18 precipitation measuring stations located on the Test Site. Ten of the wind and three of the temperature stations that reflect major terrain effects at and near the Nevada Test Site provided telemetered information for use just prior to and immediately following each nuclear detonation. 36 FIGURE 11.—U.S. Weather Bureau stations furnish information every six hours for forecasting purposes.
