Snow: Nature White Goddess


There is a strange and magical human fascination with snow. It will be for his slow and mesmerizing way of introducing, or their ability to accumulate in the ground forming a large white blanket that mutates every appearance of the landscape. The truth is that as few weather phenomena, snow is both so revered as hated as obstructive and dangerous trim.
 Snow is a meteorological phenomenon that is the precipitation of small ice crystals. These crystals adopt shapes with fractal characteristics and grouped into flakes.Snow is commonly formed when water vapor deposition undergoes high in the atmosphere at a temperature below 0 ° C, and subsequently falls on the ground. Snowfall varies depending on time and location, including latitude, elevation and other factors that affect the climate in general. At latitudes closer to Ecuador, there is less chance of falling snow. 35 ° is often referred to as a delimiter. Some mountains, even at or near the Ecuador, have a permanent snow cover on their upper parts, including Mount Kilimanjaro in Tanzania, and the Andes in South AmericaAn interesting question is why the arms of snowflakes are symmetrical, and why no two snowflakes appear to be identical. The symmetry of the arms of the Ampos always six arms from the hexagonal structure of the ice crystals along with their regular basic plane. The arms of a snowflake independently grow in an environment that is thought to vary rapidly in their temperature, humidity, etc.. These differences lead to the observed lack of correlation between various forms of snowflakes.Sometimes unexpected snowfall deteriorating infrastructure and disrupt services even in regions that are accustomed to them. The traffic can see hampered or even stopped altogether. Basic infrastructure such as electricity, telephone and natural gas can be interrupted. A snowy day is often a day in which the school or other services are canceled due to rain.
