What is Blizzard?
A '''blizzard''' is a severe [[snowstorm]]. It brings low [[temperature]]s, strong [[wind]]s, and a lot of blowing [[snow]]. Blizzards start when a [[high pressure area|high pressure system]] touches a [[low pressure area|low pressure system]]. The word ''blizzard'' is sometimes used incorrectly by [[news|news media]] to talk about big winter storms, even if the storm is not a blizzard. ==Geography== Some areas are more likely to be hit by blizzards than others, but a blizzard can occur in any place where snow falls. In [[North America]], blizzards happen often in the northern-east [[United States of America|states]], and in the provinces of [[Canada]]. In this region, blizzards can happen more than twice each [[winter]]. They also occur often in the mountain ranges of western North America. Because these regions have low [[populations]], blizzards sometimes are not reported. ===Whiteouts=== A very dangerous type of blizzard is a [[Whiteout (weather)|whiteout]]. In a whiteout, [[downdraft]]s and snowfall are so thick that people cannot tell the ground and sky apart. People caught in a whiteout lose their sense of direction very fast. This is a large danger to [[pilot]]s when they are flying [[airplane]]s, because they cannot tell how close they are to the ground, and may crash. ==== Who cleans up after blizzards? ==== The community cleans up after a snowstorm/blizzard occurs. Blizzards only usually go for 3 hours so everything won't be too damaged, meaning it won't be as hard as an [[earthquake]] or [[tsunami]] to clean. === How deep the snow gets === These horrible blizzards can achieve up to {{convert|25|ft}}-{{convert|30|ft}} deep. A basketball hoop is {{convert|10|ft}} high, so a blizzard can get snow as deep as the height of two or three hoops. == How do blizzards occur? == First, there needs to be cold enough [[air]] to cause snow to fall in the clouds and ground level water and [[moisture]] is needed to form [[cloud]]s and [[precipitation]]. The moisture is called [[water vapour]] to make the clouds
