Extremely St. Elmo´s Fire on Mt. Hoher Sonnblick
Last night the webcam of foto-webcam.eu registered on Mt. Hoher Sonnblick (3106m, Hohe Tauern, Austria) stunningly St. Elmo’s fire again. And as in the first case, the small purple flames were not caused by thunderstorms, but by a combination of heavy snowfall and wind.
The diagrams show the measured field strength in conjunction with the fallen precipitation which is completely fallen as snow.
A time-lapse recordings of different webcam shows the unusual length of the St. Elmo´s Fire.
Thanks to Hermann Scheer from the Meteorological Observatory Hoher Sonnblick, Austria for the interesting material.
