A sudden, short-duration surge of high voltage along a power line or in a piece of electrical equipment. Voltage spikes are induced into the system by lightning or by some inductive equipment being turned off. These high-voltage spikes can damage many types of semiconductor devices.
Surge protectors are used to bypass voltage spikes to ground, so they cannot cause damage.

More simply, a front is the boundary between two different air masses. frontal zone (meteorology). A front or zone with a marked increase-of-density gradient. The term frontal zone is used because fronts are not truly a ‘surface’ of discontinuity, but, rather, a ‘zone’ of rapid transition of meteorological elements.
Industry:Aviation
