A spark system gives each particle an upward speed of MinZVelocity plus a random amount below this value, in leptons a frame. The stock spark types set MinZVelocity=40 and ZVelocityRange=15, so each spark’s upward speed is picked from 40 to 54 leptons a frame. Raising MinZVelocity throws the whole shower higher, while a wider range spreads the sparks over more heights. XVelocity explains how the system then steers each spark and which systems read these settings.
A firestorm explosion thrown by DefaultFirestormExplosionSystem adds one random vector to every spark in a burst. That vector’s vertical part is a random amount below this value in either direction, without MinZVelocity, so it can tilt the whole burst up or down. In those explosions, sparks can be thrown downward only when this value exceeds MinZVelocity by at least 2.
