The steppe is windy all day. It's especially windy in the mornings and evenings. The ground where the warm wind doesn't touch is covered in snow, and light gets reflected back into space. In the land where the warm wind blows, sunlight hits the ground and absorbs heat. Hot air forms above the land of warm wind and blows toward the cold side due to thermodynamics. Cold air blows back when it's nighttime and the sun doesn't heat the steppe ground.
The direction of the wind affects the hunting process. The wind carries the smell, which the steppe herbivore has already learned to associate with danger. The steppe hunter always takes the wind in front. Sometimes desperate hunters would stalk the prey for tens of kilometers, waiting for it to fall due to exhaustion. They, however, risk Wolf ambushes by doing so.
