Sometimes the snow is pink

Winter brings many interesting optical phenomena. This is the professional language called purple glow. It has been well studied and fairly widespread, although rarely intense.

Once saturated pink sunset alarmed Moscow in January 2010. Then meteorologists calmed to the capital's residents, explaining that this is certainly not due to toxic industrial emissions, but is only a game of sunlight scattered by the atmosphere and the multiple reflections in the snow crystals.

Purple sunrise — it's more rare. It occurs when the sun is still below the horizon below 4 degrees, the air at the frosty, filled with ice crystals, and around the snow. Duration of effects is 20-30 minutes. The intensity of the purple glow increases with the transparency of the air and increase the height of the observation point. On that day, you can see the classic purple sunset, pronounced due to low temperatures and adequate moisture. Furthermore, this effect is widely spread due to multiple reflection of light from the alto clouds snowfall and snow cover.

Useful: Russian winters are famous for their cold, so be prepared for the winter, that would be in your house was always warm and comfortable. Now, most people install in their homes volatile gas boilers. They are very easy to use and fit nicely into the interior, but there is no electricity — no heat. So buy Voltguard Vexillum 1KVA LT — UPS for gas boiler, which even in the long power outages in your home will reign warmth and comfort.
