Where in nature takes multicolored snow
It happens that industrial is the cause of unusual precipitation Emissions of large metallurgical or chemical enterprises. But this is just one of the reasons.
The second is connected With algae. Not all of these plants prefer heat so we thought to ourselves. Our planet has 350 species that multiply well in the snow.
One of them is chlammedonade Snowy, single-celled algae, which is able to highlight the pigment Astaxanthin, which gives the snowdrifts red or pink color as well. The smell of watermelon. Taste is not recommended – some plants are toxic. Die do not die, but diarrhea, it is quite possible, earn. Chlammedonad Snowy blooms after the darkest and cold winter period, when water begins to heat up. At first, at the expense of chlorophyll, the snow becomes greenish, but as weather clears, it pink or blushes. At a temperature of +4 ° C, plants die from "Heat". Most often, "watermelon" drifts are found in the mountains and indoor regions: in the Northern Urals, the vertices of the Caucasian Mountains, in Kamchatka, Siberia, Arctic.

Chlammedonade Snowy – not the only type of algae, causing "blooming" snow. For example, desmond algae and Rafidonem Snowy give it a green color, Nordenchelda Anchylona – brown, they also cause diatoms algae. Black snow can be seen in the Czech Mountains. Its reason is usually snowy, although some other organisms are also capable of calling such a color.
In addition to snow, there are algae, which settle on the border between ice and sea water. In winter, they slow down their development in anticipation of heat. But it is worth the sun to fit, how they immediately come to life and the ice begins to "bloom", becoming brown or dirty-brown. This is not uncommon in the Arctic and Antarctic.
The third reason for unusual staining of snow – Dust and other particles. Most often, in this case, it drops yellow, gray, pink or reddish-brown. But there are exceptions. For example, sometimes it can be two colors at once. In 2002, the inhabitants of some areas of Kamchatka were convinced of this: in their case, the snow was pink and yellow – because of the sand rising as a result of the strongest dusty storms in China. Cyclone, who walked to Kamchatka from the Japanese Sea, captured his particles, which gave snow certain shades.
