is the aforementioned form of ice hazardous?
Yes. It can cause damage to utomobiles, aircraft, skylights, glass-roofed structures, livestock, and most commonly, crops, roofs, when exceed in diameter, planes can be seriously damaged within seconds, hailstones accumulating on the ground can also be hazardous to landing aircraft,Wheat, corn, soybeans, and tobacco are the most sensitive crops to hail damage. Hail is one of Canada's most expensive hazards.
Hail
Hail can cause serious damage, notably to automobiles, aircraft, skylights, glass-roofed structures, livestock, and most commonly, crops. Hail damage to roofs often goes unnoticed until further structural damage is seen, such as leaks or cracks. It is hardest to recognize hail damage on shingled roofs and flat roofs, but all roofs have their own hail damage detection problems. Metal roofs are fairly resistant to hail damage, but may accumulate cosmetic damage in the form of dents and damaged coatings.

Hail is one of the most significant thunderstorm hazards to aircraft. When hailstones exceed in diameter, planes can be seriously damaged within seconds. The hailstones accumulating on the ground can also be hazardous to landing aircraft. Hail is also a common nuisance to drivers of automobiles, severely denting the vehicle and cracking or even shattering windshields and windows. Wheat, corn, soybeans, and tobacco are the most sensitive crops to hail damage. Hail is one of Canada's most 
what time of year is hail most likely In North America it occurs between  March and October,with the bulk of the occurrences from May through September. what does it refers to? Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet") what are the factors favoring it? Movement of dry air into strong thunderstorms over continents can increase the frequency of hail by promoting evaporational cooling which lowers the freezing level of thunderstorm clouds giving hail a larger volume to grow in. what cases of it are recorded? Megacryometeors, large rocks of ice that are not associated with thunderstorms, are not officially recognized by the World Meteorological Organization as "hail," which are aggregations of ice associated with thunderstorms, and therefore records of extreme characteristics of megacryometeors are not given as hail records where is this mentioned organization based? UNANSWERABLE who governs it? Convention of the World Meteorological Organization who are its member states? British Caribbean Territories (joint meteorological organization and membership), French Polynesia, Hong Kong, Macau, Curaçao and Sint Maarten and New Caledonia.
