A further study of the upper westerlies; the structure of the wind field in the eastern North Atlantic and western Europe in January 1950

Abstract (a) A study of 62 vertical cross‐sections through the middle‐latitude wind fields of January 1950 confirms previous conclusions regarding the broad structure of the upper westerlies. (b) A mean January section from Greenland to the Mediterranean contains a wind maximum of 60 kt at a height...

Description
Summary:Abstract (a) A study of 62 vertical cross‐sections through the middle‐latitude wind fields of January 1950 confirms previous conclusions regarding the broad structure of the upper westerlies. (b) A mean January section from Greenland to the Mediterranean contains a wind maximum of 60 kt at a height of 9 km, 61°N. Examination of mean winter‐flow patterns for the North Atlantic shows the mean south‐westerly jet stream to be a normal seasonal feature. (c) Comment is made on two features which require further study : high‐speed currents in the Arctic stratosphere and low‐latitude jet streams.
