As a hydrometeor, hail is a form of solid precipitation consisting of transparent or opaque ice granules, of various shapes (spherical or angular), size (with diameters varying between 0.5 and 50 mm) and weight (from a few grams to over 300 grams), which falls during rains, typically accompanied by stormy phenomena (thunder and lightning) and strong wind, taking the form of a storm.
Physics teaches us that a body in free fall in a fluid does not accelerate indefinitely, but stabilizes at a certain maximum speed, called “speed limit”. Such limits are reached because the body is subjected to two forces: the force of gravity which is constant and causes it to accelerate, and the force of resistance of the fluid which increases with increasing speed and causes it to slow down. When the resistance force becomes equal to the gravitational force, the body stops accelerating and continues to move at a constant speed.
A medium-sized hailstorm (body) moving in the air (fluid) reaches a speed limit of about 180 km/ h. A raindrop, on the other hand, hardly exceeds 30 km/ h.
Hail is a climatic risk that, although rare, can soon cause large natural disasters, local or regional, including damaged roofs and building facades, broken windows, damaged cars and significant losses in agriculture. For damage to roofing have a roofing company near me set up as a business you can call on for immediate repairs.
