A blizzard (暴风雪) is a severe weather condition characterized by low temperatures and strong winds, greater than 35 miles per hour, bearing a great amount of snow.
Because the factors for classifying winter storms are complex, there are many definitions of what a blizzard truly is. But it is generally agreed that in order to be classified as a blizzard, as opposed to merely a winter storm, the weather must meet several conditions. The storm must decrease visibility to a quarter of a mile for three hours running, include snow or ice as precipitation, and have wind speeds of at least 32 miles per hour, which means Force seven or more on the wind scale.
Another standard, according to Environment Canada, is that the winter storm must have winds of 40 kilometers per hour or more, plenty of snow, visibility less than one kilometer, a temperature of less than minus 25 degrees Celsius, and all of these conditions must last for four hours or more, before the storm can properly be called a blizzard.
When all of these conditions continue after snow has stopped falling, the storm is referred to as a ground blizzard. An extreme form of a blizzard is a whiteout, when the downdrafts, together with snowfall, become so severe that it is impossible to distinguish the ground from the air. People caught in a whiteout can quickly become disoriented, losing their sense of up and down as well as their sense of direction. Severe blizzards can also occur along with arctic cyclones(气旋).
Which of the following is true of a blizzard according to the first standard?
选项
A、One can’ t see anything beyond a mile.
B、One can’t see anything beyond a quarter of a mile.
C、The wind blows at a speed of 25 miles per hour.
D、The wind blows at a speed of 23 miles per hour.
答案
B
解析
根据第二段第三句“The storm must decrease visibility to a quarter of a mile…and have wind speeds of at least 32 miles per hour…”可知,根据第一种标准,暴 风雪应满足的天气状况包括:能见度必须减小到0.25英里,风速至少达到每小时32 英里。故选B。
