Not likely static electricity, but coronal discharge. There's
a difference between a static field and an electric field (a magnetic
field is something else again). A visible spark is static; coronal
discharge (St. Elmo's Fire), or plasma, is electric field activity.
And that's as much as I know. See http://en.wikipedia.org/wiki/St._Elmo's_fire
