Hail Storm is spelled as one word which is hailstorm.
The correct way to spell hail storm is hailstorm.
Hailstorms are when hail comes down in the storm instead of just rain.
Hail forms when a thunderstorm updraft lifts a water droplet above the freezing level in the atmosphere.
The frozen water droplet then accretes super-cooled water or water vapor, which freezes once it comes in contact with the frozen droplet.
This process causes a hailstone to grow.
Hailstorms caused more than 30% of all insured damages inflicted as a result of natural disasters in Australia during this period, and around three quarters of all hailstorm damage has occurred in New South Wales.
The worst hailstorm in the world was the the hailstorm occurring near Moradabad, India, on 30 April, 1888.
This hail event is said to have killed as many as 246 people with hailstones as large as 'goose eggs and oranges' and cricket balls.
Hail is a type of precipitation, or water in the atmosphere.
Hail is formed when drops of water freeze together in the cold upper regions of thunderstorm clouds.
These chunks of ice are called hailstones.
Most hailstones measure between 5 millimeters and 15 centimeters in diameter, and can be round or jagged.
