NUCLEAR WEAPONS, Outputs and Effects
thus during the positive phase, the wind blows outwards from GZ while the direction is reversed in the negative phase. The blast wind produces dynamic pressure, which has its own effects

Within milliseconds the positive phase strikes the building, the negative phase will now This action will continue through the overall cyclic duration of the blast and will have differing effects on
Wellhead Severance Report - Background - quantifying blast page.
In order to quantify the effects of blast it is necessary to find a on the positive peak (that is, on the compression phase of the blast), but there are circumstances in which a negative peak
