Or no snow in Alaska? Of course, it is. However, the reality of the amount of snow that gets Alaska, may differ significantly from the popular concept of snow in Alaska.
Many people perceive Alaska as a barren land where it is constantly in December in large amounts and where everyone lives in an igloo. Such a concept makes Alaska sound cold and white land.
In fact, Alaska has more lakes, rivers and green trees than any state in the United States. This year the staff much green and rich. But the amount of rainfall and the total amount of snow may be significantly less than you may think.
Alaska falls snowfall
Here are some average annual precipitation and snowfall results for the cross section of Alaska.
Ankeryng — 15:37 "precipitation 69 69" snowfall
Kurgan ——- 4.67 "———– 28.0"
Fairbanks —- 10.37 '———– 68.0 "

For comparison, Buffalo, NY, receives an average of 80 "to 100" of snow each year. Some areas of northern New York state, similarly affected by their proximity to the Great Lakes, receive an average of 150 "to 200" of snowfall annually. Hooker, NY, received the 1976-1977 winter, the snow 466. "
Minneapolis, Minnesota, received their highest seasonal snowfall of 98 "during the winter of 1983-1984.
As you can see from the Alaska Summarizing the above, most of Alaska is relatively dry, annually receives less than 20 "of rainfall. South-central and southeastern coastal areas receive more rainfall.
Far northern Alaska receives precipitation typical of the desert. Please note that the mound annual moisture is only 4.67 ". Of course, most of this amount falls as snow. Because of the ice under the soil and the lack of intense drying sunshine runoff and evaporation are minimal. Therefore, Northern Alaska is not of & # 39 is dry desert despite the small amount of precipitation.
Record snowfall Alaska
It is always interesting to hear about extremes and they can certainly be found in Alaska. For example, Thompson piss, a popular extreme ski and snowboard areas in the north of Valdez, once received a record 974.5 of snow "in the winter of 1952-1953's.
Thompson piss recorded 62 "of snow in one hour period in December 1955. During February 1953 Thompson piss received a record 297.9" of snow. It is almost 25 feet of snow in just one month!
The deepest recorded snow pack in Alaska, and the deepest in all of North America occurred at Wolverine Glacier on the Kenai Peninsula in winter 1976-1977's. The depth was 356. "Packed, thickening snow. The depth of about 30 feet!
For comparison, Barrow, in the dry north, received a record minimum amount of snow during the winter 1935-1936's only 3 ".
Here are some more extreme for total precipitation. Montague Island in 1976 received a record 332.29 "precipitation. It is almost an inch of rain per day! On the other hand, Barrow received only 1.61" of precipitation for the entire 1935 year.
Alaska saves a huge amount of fresh water in its glaciers. An amazing 75% of the world's fresh water is glacier worldwide and Alaska holds the majority of its share.
In Alaska, more than 5,000 glaciers, covering an area of over 100,000 square miles. Alaska has more glaciers than the entire rest of the world, including the ice fields of Antarctica and Greenland.
Valdez, Northern Switzerland
Valdez lies on the south-central coast of Alaska and receives an annual average of more than 300 "of snow Usually snowy roofs of snow is 6 feet Snow Canyon a few miles north of Valdez -.. This is somewhat frozen waterfalls Appointment of world-class climbers..
Thompson Pass, north of Valdez, boasts some of the best helicopters for extreme skiing and snowboarding throughout North America. No wonder Valdez called the "Switzerland of the North".
Annually Valdez spend winter carnival. During the winter carnival 1990 snowfall passed the mark of 500, "As part of the winter celebration the city showed the movie." Back to the beach "20 feet by 18 feet," screen ", which they carved out of the snow Beach Talk about the theater under the & # 39;. Riding on outdoors!
What is snow?
Snow – a frozen ice crystal, and the size and shape of the crystals depend on the temperature of the formation and amount of water vapor that is present in the formation.
Pure snow crystals are hexagonal, hexagonal. The basic water molecule consists of two atoms of hydrogen and one oxygen atom to form a triangle of three equal sides. During crystallization each new ice crystal bud is formed at an angle of 60 degrees. Crystallization continues until 6 of these triangles are completed. If the crystal is released into the atmosphere, it becomes more and more, and its six-sided structure becomes the basis for more complex snowflakes.
Common forms of snowflakes include stars, needles, flat plane, columns, coated columns, and abnormal dendritic groups. Some snowflakes can be up to 1 "in diameter.
For one of the most interesting human stories about snowflake research, consider the story of Wilson Bentley. He earned the nickname "Snowflake" Bentley, because in 1885 he was the first photographed a single snow crystal. He studied over 5000 snowflakes and declared that no two snowflakes, similar quotation, which is transmitted from generation to generation. anonymous since.
In 1931, when the Snowflake Bentley died, he published a book entitled: snow crystals . The book was more than 2,400 images of Snowflake Bentley.
How many words are there Eskimos for snow?
They said that the snow has 52 words in the language of the Inuit, the Inuit and Yupik. It was also said that there are 21 words and said that their more than 400. Where the truth of the truth?
The idea that, because the snow is so important in the lives of northern peoples, that to describe it should be a lot of words, has reached the level of myth. The truth is that the snow is probably about as many Eskimo words as there are English words for snow.
Climate change in Alaska
According to Senator Ted Stevens of Alaska, "global climate change in Alaska are more severely affected than anywhere in the world." Global warming trendavalasya for many years, but very few places show as much as the effects of this trend, and how much of Alaska. The average temperature over the past 30 years has risen nearly 7 degrees.
Changes associated with global warming, are, for example, that the permafrost in Fairbanks and other towns is no longer out of & # 39 is constant. Earth fell due to melting permafrost, and for many of the buildings necessary hydraulic jacks. Further north, in Barrow, there are now mosquitoes where they never existed.
In the coastal village of Shyshmaref increasingly high water eroded the land beneath the village buildings. The village may have to relocate further inland.
Spruce bark beetles killed 4 million acres of white spruce forests on the picturesque Kenai Peninsula, the largest destruction of insects ever experienced in North America. Beetles were able to reproduce twice the normal speed of the rise in summer temperatures. Dead trees are a great fire hazard in many localities, and major recreation areas are under threat.
Glaciers are retreating at incredible speed. Ledazh Balak, south of Anchorage, in the last 20 years so stepped that it is no longer visible from the visitor center. Columbia Glacier Prince William Sound is currently with the & # 39 is the fastest glacier in the world that departs from 80 to 115 feet per day. Since 1982 it has receded by more than 6 miles.
Alaska has a lot of ice and lots of snow, but the changes are taking place at a faster rate and will have a global effect.
