Wind farm

A wind farm comprising:

• a plurality of wind turbines arranged on a ground, the ground comprising:
• a first ground portion having a first ground surface and an outer periphery;
• and
• a second ground portion having a second ground surface and surrounding wholly or partly the first ground portion,
• wherein the first ground portion is covered with a reflective first artificial covering configured to provide the first ground portion with a reflecting surface having an albedo higher than an albedo of the surrounding second ground portion and generate;
• a lower temperature and a higher pressure in the first ground portion than in the second ground portion, and
• a wind having a wind speed in a direction from the first ground portion towards the second ground portion;
• and
• wherein at least some of the wind turbines are arranged in the second ground portion in such a distance from the outer periphery of the first ground portion that they are subjected to the wind coming from the first ground portion.
