Document Summary
Sever winter storms characterized by high winds, blowing snow, low visibility and low temperatures. Blizzard form when upper level winds associated with a low pressure trough interact with a surface low pressure system, blizzards typically occur on the north west side of these storms. Alberta clippers are fast moving storms east of the canadian rockies, these are drier with less snow and extremely cold temps. Blizzards on the east side of canada occur during nor easters, hurricane force winds, heavy snow fall, high waves that damage coastal infrastructure. Snow formed by cold dry air passing over warmer air over water, occurs in regions such as. Wind chill effect makes blizzards colder than other snow storms, the additional cooling effect that wind has on humans. Wind chill indexes quantify how humans lose heat in cold air that is moving. Ice storms (conditions needed for them to form)
