The weapon burst parameters governing thermal effects from nuclear weapon explosions are reviewed as part of the OCD program for assessing urban vulnerability to fire from nuclear bursts. The most important burst parameters are weapon yield, burst height, distance from target, and number of bursts. Spatial, temporal, and spectral characteristics of fireball development and thermal output are discussed as functions of these parameters. Peak blast overpressure as a function of yield, burst altitude and distance from ground zero is briefly discussed in relation to blast-caused secondary ignitions. The material presented will be useful for approximate calculations of weapon effects in analysis of urban fire vulnerability and other problems.
