How James Glaisher discovered the jet stream
James Glaisher and Henry Coxwell are best known for a dramatic balloon ascent in 1862, in which they launched from Wolverhampton and reached heights above the top of Everest within an hour. The aeronauts went on to perform many highly successful ascents, recording invaluable data of the upper atmosphere. On one trip in 1864, Glaisher noted a characteristic warm, south-westerly wind blowing above the country. His thoughts proved to be well over a hundred years ahead of their time.
