Determing design wind speeds from raw data
Determing design wind speeds from raw data
(OP)
I'm looking for guidelines on how to determine design wind speeds for given return periods from raw climate station data.
I'm also interested in the importance of the frequency of data collection. I'm dealing with information that, at different locations, been collected at either 3 hourly, hourly or daily intervals.
If anyone can help me out or point me towards a good resource I'd be very grateful.





RE: Determing design wind speeds from raw data
If you're designing a wind farm for power generation then direction may not be an important factor.
If you're designing a structure and need to calculate wind loads you can get some clues from building code requirements.
Always helps in this forum to tell people where your project is.
good luck

As an alternative, you might look to MIL-STD-310 or some of the industry standards for wind design.

Hence, taking a reductionist approach in which only wind velocities are counted on, you will need first to identify a distribution of the measured wind velocities that matches the best the data, and then use such distribution to ascertain which top velocity is not exceeded but in 5% of the measures. You may also do this just over the data, or their average for representative points for the zone or height etc. You have then determined a characteristic wind speed and then derive with the usual formulas the wind forces.
