What is the reason for this fungal form? Why do we encounter mushroom clouds, not a expanding fire ball in nuclear explosions?

How does this shape occur?

Power explosions in the bombs form hot air spheres in the first stage.

Since the hot air is also rising up, the middle of the spheres are faced with a much more lifting force than the edges. In addition, although the hot air spheres rise as a whole, the cold weather outside the spheres begins to flow into the lower parts.

This causes the rising clouds or the spheres to take this form. In addition, the hot air molecules move rapidly because they are filled with intense power, and the space in the middle goes on to the throne. For this reason, they have a form that almost resembled fungus.

There are also different varieties of these mushroom clouds.

The states of the clouds released from the bombs vary depending on the height of the bomb and the explosive efficiency of the bomb. There are two different parts of the explosions again.

For example, in the explosions on Nagazaki and Hiroshima cities, the first part consisted of white cloud waves. These clouds occurred due to the surrounding air and heavy water.

The other part was the brown clouds that made up the stem of a mushroom. This part consisted of issues and rubbles that extend the upper truth from the ground. In addition, the clusters of clouds were not adjacent to each other.

In fact, there are different reasons why these clouds do not come into contact with each other.

If a bomb is exploded at a height of more than 600 meters from the ground and not strong, this fungus form does not clearly form. In other words, in order for the clouds created by a detonated bomb to become this state, the bombs need to be as close to the ground and the bombs should be very strong.

In summary, mushroom clouds emerge with a large heat release. The combination of this high heat and power explosion creates the head of a vacuum, that is, mushrooms. This vacuum is filled with smoke and various rashes and forms the center of the mushroom cloud.

Depending on the weather conditions, air currents and winds remain in the atmosphere for a while until they distribute this mushroom cloud.
