Wind Speeds

Mean wind speeds  14 january 2015png

windspeed velocity

Highest gust wind speed recorded by Met Eireann was 98 knots (50.42 m/s).

Highest 10-minute mean wind speed recorded by Met Eireann was 71 knots

71 knots = 36.53 m/s

According to the The wind velocity used for the design of the proposed light poles for Pearse Stadium is only 27m/s.

Wind measurements over land are usually taken at an effective level of 10m. Where readings are for heights above or below this level a correction factor is required as wind speeds increase with height and hence reduced drag from the earth’s surface.

wind speed corrections for height

The proposed light columns extend to 36.6m in height and in addition their bases are a little above sea level. The corrections required as per the above table are therefore significant.

For the convenience of those used to using different measuring systems the following table gives comparisons.
