In Mongolia, the climate is strongly continental, with long, frigid winters and short, warm summers: the temperature range between winter and summer is definitely wide.

Precipitation is scarce and is concentrated in summer, when the country is partly affected by the Asian monsoon; in winter, when a thermal high pressure system dominates, the sky is often clear and frequent throughout the year, so there's plenty of sunshine.
