Winter season

In Mongolia, winter is the coldest and longest season. In winter the temperature drops so that all rivers, lakes, streams and ponds are frozen. Many rivers freeze almost to the bottom. It's snowing across the country, but not heavy. Winter begins in early November and lasts about 110 days until March. Sometimes it snows in September and November, but the heavy snow usually occurs in early November (in December). In General compared Russia with the snow very little. Winter in Ulaanbaatar dust rather than snow. Although with climate change it is noted that in winter in Mongolia began to drop more snow. And snow is a real disaster for pastoralists (DSWD).
The coldest month of the year is January. In some parts of the country the temperature drops to -50 degrees. It should be noted that the cold weather in Mongolia is tolerated much better, because of dry air. For example: temperature -20 degrees in Ulaanbaatar is also transferred as -10 degrees in the Central part of Russia.
