Line-Squalls

Abstract

The subject of “Line-squalls” is one which has not been entirely neglected in the proceedings of this Society, but it has not hitherto been treated in any degree of detail. Sir Napier Shaw, in a lecture delivered on January 7th, 1914, on the subject of “Wind Gusts and the Structure of Aerial Disturbances,” briefly cited the line-squall as a phenomenon involving a violent commotion in the atmosphere, illustrating his remarks by sketches and meteorological records relating to a well-marked instance on October 14th, 1912, at Aberdeen.
