Abstract: By means of satellite photographs originally analyzed by Oliver et al., it is shown that the polar-front jet stream and the subtropical jet stream do not behave as entities in regions where they approach each other closely. ...

Abstract: The motion of properly selected clouds derived from photographs taken by the geostationary Advanced Technology Satellites provides estimates of the wind at cloud level. A large number of low- and high-cloud motions near ...

Abstract: The purpose of this study is to evaluate the reliability of locating jet streams by means of certain cloud patterns in TIROS pictures, and to determine the most definitive characteristics of those patterns. It would be ...
