Weather

Weather words (storm, rain, snow, sun, cloud, wind, lightning, thunder) carry historical weight in Morse code because weather telegraphy was one of the first commercial uses of the technology. The U.S. National Weather Service began transmitting daily weather summaries by Morse in the 1870s, and ships at sea relied on Morse-coded storm warnings until satellite communications took over in the 1990s. Today, weather Morse appears in storm-chaser jewelry, meteorology-themed gifts, and the call letters of weather stations that still identify themselves in CW. Most weather words run 4 to 9 letters with mixed-rhythm patterns.
