Abstract : The subtropical jet stream is investigated during a winter period and its mean velocity and location determined over the west coast of South America. The area of study is along 75W longitude in the Southern Hemisphere and extends from 11 to 43S latitude. A method of isobaric profile analysis is proposed that allows the derivation of those wind reports missing from regularly scheduled aerological soundings. A wintertime 30-day series of upper air data is studied and vertical cross sections constructed of the mean zonal winds-one from all observed wind reports and the other of all observed winds plus those derived by the analysis method. Both cross sections are compared with similar seasonal investigations over South America, North America, Australia, and New Zealand. (Author)
