The Helm Wind

The Helm Wind (the only named wind in the British Isles) is a very strong wind which may blow from off the Pennines, between Mickle Fell to just north of Cross Fell, when the wind direction is from between the NNE and East. It occurs more frequently in the spring and summer and may last from a few hours to several days. A wind blowing across the Pennines from the East is forced upwards and increases speed as the air is forced to flow through a smaller cross-sectional area. As it blows off the hills over the Eden Valley it forms a vortex which creates a line of cloud along the valley known as the Helm Bar. Cloud, known as the Helm Cap, also forms over the tops of the peaks.

A full discussion of the wind is provided by David Uttley in his book The Anatomy of the Helm Wind published by Bookcase, 1998.
