The Genius of Accidents: Jet Streams - Episode 4

Before the eruption of Krakatoa in 1883, nobody knew about the
invisible streams of air in the middle atmosphere that are
important for air travel and meteorology.


Adam Hart explores the archives of the Royal Society in London to
reveal a story of how global observations of the atmospheric
effects caused by the ejected smoke from Krakatoa unexpectedly
revealed the presence of the jet streams.
