Why can hail when the temperature is over 30 degrees?
It is very hot in summer and the ground temperature is very high, which is easy to produce a lot of hot and humid air near the ground; These hot and humid air rises rapidly and the temperature drops sharply. The water vapor in the hot air condenses into water droplets, which are quickly frozen into small ice beads because of the low temperature. Affected by the airflow, these small ice beads rolled up and down in the clouds, constantly adhering and condensing the surrounding water droplets into ice, getting heavier and heavier, and finally falling from the sky. This is hail.
Hail only occurs when a large amount of warm and humid air rises rapidly, so hail mostly occurs in summer, mostly in local areas, with little impact. In winter, the temperature near the ground is very low, so it is impossible to produce strong and rapid updraft and hail.
