Body
Warren, here is one especially for you since you an Old Salt Sailor!
http://mysite.du.edu/~jcalvert/phys/elechome.htm Scroll down to
electric wind!
Similar discharges may be seen at the end of lightning rods (though
normally they are not luminous enough to be seen), or at the ends of the
masts or yardarms of sailing ships, where they were called St. Elmo's
Fire. This happens when the atmospheric electric field becomes very
large due to the passage overhead of a cumulonimbus. The major charge in
the lower part of a thunderhead is negative, so the discharge is usually
a positive corona. However, sometimes there is a positive charge at the
very base of the cloud, which may produce a negative corona. In
Graeco-Roman times, St. Elmo's Fire was attributed to Castor and Pollux.
St. Elmo was apparently St. Erasmus of the 4th century, patron saint of
sailors, and many forms of his name have been used. It had superstitious
significance as well, and was sometimes called Corposanto, which English
sailors called Corbie's Aunt. It was generally a favorable omen, but a
man whose face was illuminated by it was doomed to die within a day,
some believed. Since relatively dry air is required, it usually
signified the end of rainfall and stormy weather. It can also occur on
aircraft flying in the strong electric fields around thunderstorms.
Corona discharges usually produce radio noise, as we found in the First
Experiments above. Corona is effective in transferring charge without
actual conductive contact, of which the Wimshurst machine and the van de
Graaff generator furnish examples.
I personally have seen this a lot flying over the desert SW in the right
atmospheric conditions!
