A blizzard is a severe snowstorm characterized by strong sustained winds of at least 56 kmh and lasting for a prolonged period of time. Blizzards can bring whiteout conditions, and can paralyze regions for days at a time. In Antarctica, blizzards are associated with winds spilling over the edge of the ice plateau at an average velocity of 160kmh.
About Blizzard in brief
A blizzard is a severe snowstorm characterized by strong sustained winds of at least 56 kmh and lasting for a prolonged period of time. A ground blizzard refers to a weather condition where loose snow or ice on the ground is lifted and blown by strong winds. Blizzards can bring whiteout conditions, and can paralyze regions for days at a time, particularly where snowfall is unusual or rare. In Antarctica, blizzards are associated with winds spilling over the edge of the ice plateau at an average velocity of 160kmh. A nor’easter is a macro-scale storm that occurs off the coast of New England and Atlantic Canada. The term comes from the wind associated with many different types of storms which can form in the North Atlantic Ocean and some of which form as far south as the Gulf of Mexico. The first recorded use of it for weather dates to 1829, when it was defined as a ‘violent blow’. It achieved its modern definition by 1859, when It was in use in the western U.S.
during the harsh winter of 1880–81. In the United States, storm systems powerful enough to cause blizzard usually form when the jet stream dips far to the south, allowing cold, dry polar air from the north to clash with warm, humid air moving up from the south. When a cold front and warm front mix together and a blizzard forms at the border line. Another storm system occurs when a cold core low over the Hudson Bay area in Canada is displaced southward over southeastern Canada, the Great Lakes, and New England. It gets its name from the direction the wind is coming from. More specifically it describes a low-pressure area whose center of rotation is just off the Atlantic coast of Canada and just south of the Gulf of Mexico. In a true whiteout there is no visible horizon. Motorists can become lost in their own front yards when the door is only 3m away, and they would have to feel their way back.
