Wind rose and prevailing Winds

I have a doubt about prevailing winds? Do prevailing winds mean intensity? or % of time.
N-W and S-W here are both getting same % of time (radial) then why is the answer N-W only? and not both NW and SW?

Hi @RITIKAKAPOOR1311,

Which question are you referring to - was it in a Practice Exam or Quiz? If so, can you please let me know the Form or Quiz # so that I can locate the specific question?

In general, a prevailing wind means % of time (not necessarily intensity). Our new PA content covers this topic well and I recommend you check out this video for more information.

Hope this helps!
