Change in hail size due to more humid air According to experts, hail is formed when water droplets are rolled upward in the form of a storm. How fast the hail grows depends on the amount of moisture in the air. More humid air will bring more and bigger hail. It will keep growing until the wind speed is strong enough to keep it up.
The study is published in Limelight and Atmospheric Science. According to this, due to heavy storm, the speed and size of hail will increase, which will increase the risk to life and property.
