The system for forcing the movement of masses of air over open areas, in particular the stimulation and maintenance of the airflow over open urbanised areas, comprising elements for forcing the movement of air on support elements, shall be characterised by at least: of the bottom line (L1, L2, L3) designated on the ventilated area, at least two air force elements (W1, W2, W3, W4, W5, W6) are aligned in the same direction, seated on the support elements and separated from each other at a distance between 29H and 51； H,where H is the height from the base plane of the support element to the axis of attachment of the air -moving element (W1, W2, W3, W4, W5, W6). With the air -force elements aligned on the same line generating,flowing in the same direction, a stream of air with a flow rate of at least 4700 m3 /s. The height from the base plane of the reference element s to the axis of attachment of the force -to -air element (W1, W2, W3, W4, W5, W6) is within 40m to 60m.
