《暴风雪》 作者：苏珊·伦诺克斯 核心问题 暴风雪是什么？它会对人们产生什么影响？

The Great White Hurricane On a March Sunday in 1888, it began to rain in New York. The temperature dropped quickly as night fell. The rain turned to ice, then to snow. On Monday, people woke to howling winds. Snow piled high in the streets. The Great White Hurricane lasted three long days. The storm buried the northeastern United States.

白色大飓风 1888年3月的一个周日，纽约开始下雨。 夜幕降临时，气温骤降。 雨水结成了冰，接着又变成了雪。 周一，人们在呼啸的狂风中醒来。 街上的雪堆得高高的。 这场白色大飓风持续了漫长的三天。 这场风暴掩埋了美国东北部地区。

When it was over, more than 400 people had died. The storm caused millions of dollars in damage. It would be summer before the last of the snow would melt. The blizzard of 1888 was one of the worst storms in history.

风暴结束时，已有400多人遇难。 这场风暴造成了数百万美元的损失。 要等到夏天，最后一片积雪才会融化。 1888年的暴风雪是史上最严重的风暴之一。

Extreme Storms Three things turn a snowstorm into a blizzard. Strong winds, blinding snow, and freezing cold. In a blizzard, winds blow at speeds of 35 miles, 56 kilometers per hour. They blow for at least three hours. Wind gusts may even reach a hurricane force of 75 miles, 119 kilometers per hour or more.

极端风暴 三个因素会让雪暴转变为暴雪。 强风、迷眼的大雪以及严寒。 暴雪的风速可达每小时35英里（56公里）。 这样的大风至少会持续三个小时。 阵风的风速甚至能达到飓风级的每小时75英里（119公里），甚至更快。

The winds whip snow through the air, making it hard to see. This is known as a whiteout. A whiteout is when no one can see anything more than a quarter of a mile, 402 meters away. Safe travel is nearly impossible during a whiteout.

狂风卷起空中的雪，让人很难看清东西。 这种现象叫做“雪盲现象”。 出现雪盲现象时，人们看不到四分之一英里（402米）以外的任何东西。 雪盲天里几乎不可能安全出行。

Blowing winds also create something called wind chill. Wind chill causes the body to lose heat faster. Skin feels like it is in air that is much colder. Wind chill can cause bare skin to freeze.

呼啸的狂风还会带来一种叫做“风寒效应”的现象。 风寒效应会让人体的热量流失得更快。 皮肤会感觉周围的空气比实际要冷得多。 风寒效应还会让裸露的皮肤冻伤。
