Sljeme Mountain
Medvednica () is a mountain in central Croatia, just north of Zagreb, and marking the southern border of the historic region of Zagorje. The highest peak, at is Sljeme. Most of the area of Medvednica is a nature park (''park prirode''), a type of preservation lesser than a national park. The area of the park is and about 63% is covered with forest. During Miocene and Pliocene, the mountain was an island within the Pannonian Sea. Etymology The name Medvednica could be translated as "bear mountain", there being other toponyms on the mountain using the Kajkavian dialect term ''medved'' (standard Croatian "medvjed" = bear), notably Medvedgrad, a medieval castle on its southwestern edges. Sljeme () (''Sleme'' in Kajkavian) means ''summit'', and it is a name often used to refer to the entire mountain. Climate The climate of the Medvednica mountain is typical for Central European mountain ranges. The average annual precipitation is around 1300 mm (cf. 840 mm at Z ...

Artificial Snow
Snowmaking is the production of snow by forcing water and pressurized air through a "snow gun", also known as a "snow cannon". Snowmaking is mainly used at ski resorts to supplement natural snow. This allows ski resorts to improve the reliability of their snow cover and to extend their ski seasons from late autumn to early spring. Indoor ski slopes use snowmaking. They can generally do so year-round as they have climate-controlled environments. The use of snowmaking machines has become more common as changing weather patterns and the popularity of indoor ski resorts create a demand for snow beyond that which is provided by nature. Snowmaking machines have addressed the shortage in the supply of snow; however, there are significant environmental costs associated with the artificial production of snow. According to the European Environment Agency, the length of snow seasons in the northern hemisphere has decreased by five days each decade since the 1970s, thus increasing the dema ...

Chairlift
An elevated passenger ropeway, or chairlift, is a type of aerial lift, which consists of a continuously circulating steel wire rope loop strung between two end terminals and usually over intermediate towers, carrying a series of chairs. They are the primary onhill transport at most ski areas (in such cases referred to as 'ski lifts'), but are also found at amusement parks, various tourist attractions, and increasingly in urban transport. Depending on carrier size and loading efficiency, a passenger ropeway can move up to 4000 people per hour, and the fastest lifts achieve operating speeds of up to or . The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1200 people per hour at rope speeds of up to . The four person detachable chairlift ("high-speed quad") can transport 2400 people per hour with an average rope speed of . Some bi and tri cable elevated ropeways and reversible tramways achieve much greater operating speeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Queen Trophy
Snow Queen ( hr, Snježna kraljica) is a World Cup alpine ski race held in the hills of Zagreb, Croatia. The men's and women's slalom races take place on the Medvednica mountaintop Sljeme, just north of Zagreb, usually in early January. The women's race debuted in 2005 and the men's event was added three years later in 2008. The events are held on the red run ski track ( Crveni spust) on Medvednica, starting at an elevation of and ending at . Besides the city events in Moscow and Munich, it is the only World Cup event held near a large metropolitan area.

Slalom Skiing
Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super-G, super giant slalom and Downhill (ski competition), downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter Games. History The term slalom comes from the Morgedal/Seljord dialect of Norwegian language, Norwegian word "slalåm": "sla", meaning "slightly inclining hillside", and "låm", meaning "track after skis". The inventors of modern skiing classified their trails according to their difficulty. ''Slalåm'' was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. ''Ufsilåm'' was a trail with one obstacle (''ufse'') like a jump, a fence, a difficult turn, a gorge, a cliff (often more than high) and more. ''Uvyrdslåm'' was a trail with several obstacle ...

Alpine Skiing World Cup
The FIS Alpine Ski World Cup is the top international circuit of alpine skiing competitions, launched in 1966 by a group of ski racing friends and experts which included French journalist Serge Lang and the alpine ski team directors from France (Honore Bonnet) and the USA ( Bob Beattie). Also available under . It was soon backed by International Ski Federation president Marc Hodler during the FIS Alpine World Ski Championships 1966 at Portillo, Chile, and became an official FIS event in the spring of 1967 after the FIS Congress at Beirut, Lebanon. On January 5, 1967, the inaugural World Cup race was held in Berchtesgaden, West Germany, a slalom won by Heinrich Messner of Austria. Jean-Claude Killy of France and Nancy Greene of Canada were the overall winners for the first two seasons. Rules Competitors attempt to achieve the best time in four disciplines: slalom, giant slalom, super G, and downhill. The fifth event, the combined, employs the downhill and slalom. The World Cup ...

Ice Break
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly ( quenching), up to three types of amorphous ice can form depending on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoarfrost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar frost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relative Air Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 28 g of water per cubic metre of air at , but only 8 g of water per cubic metre of air at . Three primary measurements of humidity are widely employed: absolute, relative, and specific. Abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insolation
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), p. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, the height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
