The Story of the Hovm÷ller Diagram: An (Almost) Eyewitness Account

Persson, Anders

Année de publication
The Hovm÷ller diagram or the trough-ridge diagram, a simple longitude?time diagram, was designed in 1948 by Ernest Hovm÷ller (1912?2008) to help understand certain features in the dynamics of the atmosphere, in particular the "downstream development" phenomenon. Originally depicting the 500-hPa geopotential, today many other parameters are used, and Hovm÷ller diagrams have during the last 25 years found a rapidly increasing use in a wide range of atmospheric research.
