The Hovmöller diagram or the trough–ridge diagram, a simple longitude–time diagram, was designed in 1948 by Ernest Hovmöller (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 Hovmöller diagrams have during the last 25 years found a rapidly increasing use in a wide range of atmospheric research.
