| electrical storm |
1. Popular term for thunderstorm. 2. Sometimes applied to a relatively rare condition of disturbed atmospheric electric field in the lower atmosphere that arises when strong winds are blowing and much dust is in the air, but there is no thunderstorm activity. Triboelectrification due to the blowing dust may charge fences and other metallic objects to such an extent that slight shocks are felt upon touch. 3. Same as earth-current storm.

| electric field |
1. A vector field, usually denoted by E, defined as follows: at a given time and at each point in space the force experienced by a positive charge (sometimes called a test charge) at that point divided by the magnitude of the charge, taken to be sufficiently small that it does not affect the positions and velocities of all other charges. The set of all vectors thus obtained is the electric field, although this term is often used for its value at any given point. ...
