Fireball

As Fireball (also Isothermalsphäre or firebladder ) is generally described in explosions and especially in atomic bomb explosions that ardent cloud that forms around the explosion center. The fireball of a nuclear explosion consists partly of the gaseous remnants of the nuclear weapon, for the most part, however, from air that has been heated by radiation or by the shock wave and partially ionized. The fireball is optically recognizable as a roughly spherical, brightly shining cloud and clearly separated from the environment, such as high-speed footage of nuclear tests show. In the core of the fireball temperature of more than 1.5 million degrees centigrade can occur. Touched the fireball the ground, it is called a ground explosion, otherwise by an air blast.

For non- nuclear explosions, the shape, luminosity and demarcation of the fireball on the type of explosive or fuel used depends. For cinematic purposes are often offset with gasoline pyrotechnic compositions used to produce particularly impressive, durable fireballs.
