Sometimes the strong winds create white outs when the snow blows so much. During the summers the top layer of sil thaws but the underlying piece of soil remains frozen. During the summer rainwater can't soak into the soil so the Tundra has shallow ponds and marshy areas over the summer. Near the Arctic Circle the sun doesn't set during the midsummer. Animal Species: A large variety of animals live in the tundra for the whole year. They have special adaptations that allow them to survive in the winter weather.
