Whose observations discovered the jet stream?
Quick Answer
Wasaburo Oishi made early upper-air balloon observations in Japan that revealed strong high-altitude winds. His work helped identify the jet stream before it became widely known.
The Full Story
Wasaburo Oishi, a Japanese meteorologist, used pilot-balloon observations in the 1920s to study winds high in the atmosphere. He discovered a powerful current of fast-moving air at upper levels, especially over Japan. Although his work was not widely recognized internationally at first, it was an important early step toward understanding the jet stream. Jet streams are now known to influence storm tracks, aviation, and weather patterns across the globe.
