What are blizzards and How do they form? Blizzards are severe winter storms that involve very low temperatures(-20 to –40°C), and strong winds. The winds usually exceed 35mph. Blizzards are a type of storm that occurs when warm and cold air masses intermix and attempt to equalize their temperatures. Blizzards form when warm air moving north collides with a cold air mass that has been pushed down from the Arctic. During a blizzard it doesn’t actually have to snow. The winds will stir up the snow on the ground and we’ll end up with a blizzard.
What time of Year do Blizzards Occur? Blizzards occur during the winter solstice between the months of November through March in the Northern hemisphere, and May through September in the Southern hemisphere. An occasional blizzard may occur during the end of October in the North and April in the South.
In Which Area Of the World are Blizzards Most Common? Blizzards are most likely to occur in the Eastern Coast of the U.S. and portions of the Plains. In Canada blizzards occur in the Southern Prairies, the Maritimes, and the Eastern Arctic. It is least likely to occur in places of warm, tropical climates such as: Florida, Arizona, and Hawaii. The only type of blizzard that may occur in these regions are Sand Blizzards.
The Potential for Destruction Blizzards have a high potential for destruction. Accumulation of snow on tree branches cause many trees to break and fall on cars, houses, and block streets. Highways and airways experience major delays because of the large amounts of snow and lack of visibility. People are forced to stay home from school and work, also their daily activities are limited. Elderly people are at high risk for severe injury or death because of the lack of aiding.
Have there been any such Occurrences in this Area? On January 31st, 2002 a blizzard struck the city of Windsor. This unexpected blizzard took out power lines, damaged the natural surroundings, and caused deaths. Students all over Windsor and Essex-County were forced to leave and stay home from schools, and others were unable to attend work. This was the most recent blizzard in our area. The “Blizzard of 2002” had a strong after affect on the city of Windsor and is still talked about today.
Some of the Biggest and Deadliest Blizzards • 1888 March 11-14 in Eastern U.S-400 people • died- 1940 November 11-12 Midwest U.S.-144 people • died- 1956 Feb. 1-29 West Europe-1,000 people died- 1958 Feb. 15-16 North Eastern U.S-171 people • died- 1967 Dec. 12-20 South West U.S-51 people died- 1988 in New York- 400 people died- 1993 March 13-14 Eastern U.S-200 people died- 1996 Jan. 7-8 Northeastern U.S- 100 people • died- 1996 Aug. 22 Himalayas India -239 people died
Factors of Weather that Interact to Produce Blizzards *Cold Climates (-20 to –40°C) *Wind (up to 35mph) *Moisture (lake effect) *Snow fall or on the ground
Other Exciting Details and Facts about Blizzards • Approximately 100 people die each year because of blizzards. (70% of deaths occur on the roads in automobiles) • Blue Canyon, California usually gets 241 inches of snow each year. The snowiest large city is Syracuse, New York which gets 112 inches of snow on the average each year. • Most objects get their colour because they absorb a particular frequency or colour of visible sunlight. Snow reflects sunlight, and thus doesn't absorb any colour.
Extreme Heat HEAT is a form of transformed energy and is transmitted by convection, radiation, or conduction. Extreme heat conditions are formed when temperatures are 10 degrees or higher in a certain region. This usually occurs for several weeks in the summer solstice most frequently occurring in July and August in the Northern hemisphere. Effected regions in North America include East, mid-West, North-east and in the South. Areas with high humidity are the most unbearable. On June 20, 1953 extreme heat occurred in Windsor at 3:30pm with temperatures reaching 35°C. Heat conditions such as these cause many deaths, dehydration and disorders such as heat stroke or sun stroke, heat exhaustion, heat cramps, and sunburns. An interesting fact is because men sweat more than women, men are more vulnerable to heat illness because they become dehydrated quicker.
Extreme Cold COLD is a low temperature range that is very uncomfortable. Extreme cold occurs when there are actual temperatures below freezing and when the low temperature and cooling effect of the wind combine to create wind chill. Cold conditions occur in the winter solstice during the months of December through March, in the Northern hemisphere. This would least likely occur in the summer due to the warmer weather. Near the poles are the most common places that extreme cold would occur because the temperatures are at their lowest in these areas. In Snag Airport, Yukon, at 7:20am on February 3, 1947 the temperatures dropped to -50°C. Exposure to the cold can cause frostbite, hypothermia, or even death. People that are most vulnerable to extreme cold are infants and the elderly.
