About Hail In The US – Protecting Your Condenser Coils From Damage
WHAT IS HAIL AND WHAT IS CONSIDERED DAMAGING SIZE HAIL?
Hail is destructive chunks of ice that falls from the sky causing over $1 billion annually in the US alone. Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage HVAC Equipment including condenser coil and cooling tower fill, aircraft, homes, office buildings, cars, crops and more. Hailstones grow by colliding with supercooled water drops. Supercooled water will freeze on contact with ice crystals – The hail falls when the thunderstorm’s updraft can no longer support the weight of the ice or the updraft weakens. The stronger the updraft the larger the hailstone can grow and the more damage they can do. Hail stones generally fall at higher speeds as they grow in size, though complicating factors such as melting, friction with air, wind, and interaction with rain and other hail stones can slow their descent through Earth’s atmosphere. Severe weather warnings are issued for hail when the stones reach a damaging size, as it can cause serious damage to man-made structures and, most commonly, farmers’ crops. Although the diameter of hail varies, in the United States, the average observation of damaging hail is between Quarter Size (1 in) and golf ball-sized (1.75 in).
