Source mile fun for children and a thousand headaches for motorists without chains or tires for the snow inevitably makes us love winter. It always looks forward although sometimes cursing its abundance sometimes disadvantageous. Know that there moult exciting things to know about the snow that you no doubt can not be.
A History of crystals
Taking birth in the high atmospheric altitudes as crystals that are piling up in snowflake, snow is formed only when weather conditions well defined. It is for this reason that many countries do not have the chance to see snow falling in their country. The snow formed at the cold cloud masses. Below 0 ° C, water vapor solidifies into crystals. To become crystal water molecules require the presence of small particles such as dust or smoke. Then forms crystals of hexagonal structure, which agglutinated. If the ground temperature is cold rolled form a coat can be thin or very thick, very dense or powdery.
Observed under a microscope or a powerful magnifying glass, the ice crystals that form snow have different forms according to various criteria, including temperature and density of water vapor. In 1930, a Japanese researcher has isolated seven categories of shapes of snow crystals. Thus we have platy crystals in dendrite, star, needle, cufflink, column and finally the crystals of irregular shape. Each shape category, thousands variations may occur depending on the cycle of crystallization and temperature of the successive layers of the atmosphere through. By its structure, the snow can easily form a ball that is thrown joyfully in a battle of snowballs.
Snow, society and legends
In Canada, the Scandinavian countries or Russia, countries where heavy snowfall is common in winter, cities and villages have organized to enable people not to suffer the hazards. The population of these countries also held their winter habits depending on the thickness of snowpack. In countries less prone to heavy snowfall as Europe, South UK or France, the chaos settles quickly when they exceed a certain amount of snow. It is in the mountains in the Alps or the Pyrenees for example, that one looks forward to a fully solid snow. In ski resorts, in case of lack of snow, human genius has to cope with the famous snow cannons, but nothing obviously ski holiday on good natural snow.
From the ancient Greek The snow was personified by the traits of the goddess Chion, daughter of Boreas and Orythie. Although Greece knows a Mediterranean climate, the summit of Mount Olympus, home of the gods, is snow-covered during much of the year. A stay in Greece to the small town of Litochoro, located a hundred kilometers from Thessaloniki, you will appreciate the unique beauty of this snow-capped peak. The Brothers Grimm were inspired by the color of pristine snow to create a heroine to the complexion of dazzling whiteness whose desire for a child born from the blood of a queen which fell on the snow after it pricked her finger with a needle. Thus was born the legend of Snow White. The queen, who died, has been replaced by a stepmother with a known history thanks to the animated film from Walt Disney.
