n
(Military) the blast effect of a nuclear weapon expressed as an amount of pressure greater than normal barometric pressure

overpressure

The pressure resulting from the blast wave of an explosion. It is referred to as "positive" when it exceeds atmospheric pressure and "negative" during the passage of the wave when resulting pressures are less than atmospheric pressure.
