The wind rose shows the relative frequency of the direction the wind is coming from.  It can also show the ranges and percentages in wind speeds during the time period.  I assume that you need the 3 second gust or fastest mile wind velocity for determining the lateral forces on a structure.  I am not sure how you can use the wind rose to determine these velocities.  For more information on wind roses, see:

We have a project in Nigeria, and the we were given a "wind rose" for wind loading. Anyone familiar with the use of the "wind rose"? Thanks for any input!
