What is the supercell?

Until a few years ago the word supercell was an atmospheric phenomenon unknown to us, it was present in the great American plains, but it had never occurred in Italy.

In the area of Brescia, similar phenomena were concentrated during the summer of 2019, in some situations even with serious consequences.

In the sky a large dome appears overhanging the storm.
