Studded winter tires Articles

A snow fence is a structure used to force drifting of snow to occur in a predictable place, rather than in a more natural method. Snow fences are primarily employed to minimize the amount of snow drifting onto roadways. In rural areas, farmers and ranchers may use temporary snow fences to create large drifts in basins for a ready supply of water in the spring.

Snow fences are also used in avalanche control.

A typical style of temporary snow fence seen in North America today is often one of two varieties: orange plastic attached to stakes at regular intervals or a cedar or other lightweight woodstrip and wire fence, also attached to metal stakes. A permanent snow fence is generally of larger wooden poles set deeply into the ground with large wooden planks running vertically across them. A permanent snow fence is built when a roadway is subject to predictable snow and wind patterns each winter, usually in mountain passes.

The drifting of snow behind a fence follows the laws of physics as the pressure on the downwind side is less than that on the windward side, allowing light materials such as snow or leaves to settle there.

Cold inflation pressure is the inflation pressure of tires before the car is driven and the tires warmed up. Recommended cold inflation pressure is displayed on the owner’s manual, the placard (or sticker) attached to the vehicle door edge, door post, glove box door or fuel door.

The snow line is the point above which, or poleward of which, snow and ice cover the ground throughout the year.

The interplay of altitude and latitude affect the precise placement of the snow line at a particular location. At or near the equator, it is typically situated at approximately 4,500 meters (or about 15,000 feet) above sea level. As one moves towards the Tropic of Cancer and Tropic of Capricorn, the parameter at first increases: in the Himalayas the permanent snow line can be as high as 5,700 metres (18,700 feet). Beyond the Tropics the snow line becomes progressively lower as the latitude increases, falling all the way to sea level itself near the poles.

In addition, the relative location of a mountain to the nearest coastline can be a factor in how high the snow line would be; a peak near a coast — especially the west coast — of a continent might have a lower snow line than one of the same height and at the same latitude situated in a landmass interior, because the average summer temperature of the surrounding lowlands would be warmer in the latter spot than in the former, thus making a higher altitude necessary to keep the snow from melting in the summer.

Snow City (Chinese: 雪城) is Singapore’s first indoor snow centre located within the Singapore Science Centre area beside Ommi-Theatre in Jurong East. Snow City introduces the concept of snow and cold climates in a fun, entertaining and educational way. Visitors can experience real snow, a sub-zero climate and a three-storey high snow slope.

History

Snow City is a joint venture by the Singapore Science Centre and NTUC Income Co-operative Pte Ltd. The idea behind the collaboration was that Singapore being a tropical country, many Singaporeans have never had the opportunity to experience the cold climates and snow. With the set up of Snow City will give everybody a chance to learn more about snow, in a fun way.

The 3,000 sq-metre centre was built at a cost of S$6 million and was officially opened in 2000.

Highlights

Visitors will first arrived at the Air Lock, which is maintained at 10°C. This
allows visitors to become comfortable with the lower temperatures before they enter the chamber itself.

The main focus of Snow City is its Snow Chamber, a 1200 sq-metre room covered with snow. The Snow Chamber is well maintained at -5°C and snow level is kept constantly at 400mm in depth. Between 10 to 15 tons of snow is created each week in order to maintain this level. The snow is produced using a special Snow Gun, which cools water using liquid nitrogen.

Inside the Snow Chamber, is a 60 meter long high slope which is about 3 storeys high. ‘Snowtubing’ is the main activity where visitors will be sliding down the snow slope while sitting on a inflatable tube.

There is also a Snow-Play Area for the younger children.

There is a place for wine and dine on level 2, named Alphine Lodge.

Snow City’s sound educational programmes and workshops are available to schools and interested groups.

Ski & Snowboard

Lessons for skiing and snowboarding is available at a fee.

Technology

A specially designed Snow Gun is used in the production of snow on site.

Firstly, water is atomized using high-pressure compressed air. The water then arrives at the snow gun and is pushed out of the special nozzles at the end of the barrel. Liquid nitrogen which freezes at a low temperature of -196°C is also passed through the snow gun at the same time. The extreme cold of the liquid nitrogen instantly freezes the atomized water into powder-like snowflakes.

The simplified formula to produce snow is

• One ton of liquid nitrogen + one ton of water = one ton of snow.
