  • Three things are needed to make a blizzard. 1. Cold air (below freezing) is needed to make snow. For snow to fall to the ground, the temperature must be cold both up in the clouds where snowflakes form, and down at ground level. If the air near ground level is too warm, the snow will melt on its way down, changing to rain or freezing rain. 2. Moisture is needed to form clouds and precipitation. Moisture in the air is called water vapor. Air blowing across a body of water, such as a large lake or the ocean, is an excellent source of water vapor. As wind moves air over the water, some water evaporates from the surface, putting vapor into the air. This is how “lake effect snowstorms” and “Nor’easters” pick up so much moisture. However, cold air is not able to hold much water vapor. In fact, very cold air does not make very much snow. 3. Warm, rising air is needed to form clouds and cause precipitation. For a blizzard to form, warm air must rise over cold air. There are two ways that this may happen. Winds pull cold air toward the equator from the poles and bring warm air toward the poles from the equator. When warm air and cold air are brought together, a front is formed and precipitation occurs. Warm air can also rise to form clouds and blizzard snows as it flows up a mountainside.
  • A blizzard is a severe weather condition characterized by low temperatures and strong winds (greater than 35 mph) bearing a great amount of snow, either falling or blowing. Because the factors involving classification of winter storms are complex, there are many different definitions of blizzard. A major consensus is 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 consecutive hours, include snow or ice as precipitation, and have wind speeds of at least 32 mph (seven or more on the Beaufort Wind Scale). Another standard, according to Environment Canada, is that the winter storm must have winds of 40 km/h or more, have snow or blowing snow, visibility less than 1 km, a wind chill of less than -25 degrees Celsius, and all of these conditions must last for 4 hours or more, before the storm can be properly called a blizzard. When all of these conditions persist after snow has stopped falling, meteorologists refer to the storm as a ground blizzard. Severe blizzards can occur in conjunction with arctic cyclones. An extreme form of blizzard is a whiteout, when downdrafts coupled 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 direction. The word blizzard is of unknown origin, but may originate from the surname Blizzard. It was first widely used after the great American winter storm now known as the "Blizzard of 1880." (http://www.etymonline.com/index.php?search=blizzard) Certain types of blizzards in the northeastern United States are colloquially known as Nor'easters. Famous U.S. Blizzards Graph comparing the cost of damage of several famous U.S. BlizzardsThere have been many devastating blizzards throughout U.S. History. It is not uncommon for a region of the United States or North America to be struck by two devastating winter storms in one season. The Blizzard of 1888 paralyzed the Northeastern United States. In this blizzard, 400 people were killed, 200 ships were sunk, and snowdrifts towered 15 to 50 feet high. Earlier that year, the Great Plains states were struck by the Schoolhouse Blizzard that left children trapped in schoolhouses and killed 235 people. These unpredictable storms can come without much warning, causing damage and destruction to humans and infrastructure. The Armistice Day Blizzard in 1940 caught many people off guard with its rapid and extreme temperature change. It was 60 degrees Fahrenheit in the morning, but by noon, it was snowing heavily. Some of those caught unprepared died by freezing to death in the snow and some while trapped in their cars. Altogether, 154 people died in the Armistice Day Blizzard. One-hundred five years to the day (March 12) after the blizzard of 1888, a massive blizzard, nicknamed the Storm of the Century, hit the U.S in 1993. It dropped snow over 26 states and reached as far north as Canada and as far south as Mexico. In many southern U.S. areas, such as parts of Alabama, more snow fell in this storm than ever fell in an entire winter. Highways and airports were closed across the U.S. As a wider effect, the storm spawned 15 tornadoes in Florida. When the Storm of the Century was over, it affected at least half the of U.S. population; 270 people died and 48 were reported missing at sea. From http://en.wikipedia.org/wiki/Blizzards
  • alot of snow, wind and ice
  • around here they're caused by noreasters tht leave feet rather than inches.
  • your mom needs to freeze a guy and have kids. then the kids have to get screwed
  • first, your mom has to go to your friends house and screw him. then she has to go to a joint and get drunk and put her foot up her a.. tell her if she needs help im there. Oh, i forgot to tell you to get a sex transplant.
  • A blizzard is wind driven snow. You should call a big fuzzy guy friend to come over and stay with you until it has all melted away.
