Summary:

The paper presents measurements of wind speed recorded at 6, 12, 18 UTC at the automatic meteorological stations Maws 101- Vaisala on the area of tailing pond "Żelazny Most" in the period 2003-2009. Measurments were on four stations placed on different location versus the tailing pond.
Low coefficient friction on the tailing pond surface (about 600 ha) and ele-vation on the height about 60 m over the natural terrain affect the increase of wind speed. Important factors are: stations location, the hour of day and the year seasont. The biggest differences beetwen stations are obserwed at 12 UTC, the smallest at 6 UTC. The fastest wind speeds are recorded in spring and in autumn and on Zapora station.
