Ed ecco le risposte:
The hailstones travel up and down inside the thunderhead, gaining mass and size on each leg, cycling up & down several times. They are trapped in the updrafts, and at some point get so heavy that they fall to the ground. The updrafts in those storms are very powerful, and provide a lot of lift.
The strength of wind within a super cell thunderstorm shouldn’t be taken lightly. It’s the same wind that can generate a tornado, which moves objects much bigger than large balls of ice. The answer is, yes, the wind is just that strong.
Well, they don’t, that is why they fall.
Updrafts can regularly be 120km/h in a strong sgoem which can lift a 10cm hailstone, and it’s not just a ciuple hundred of feet, but several thousand metres until it’s too heavy for the updraft.
