Suggest a reason why wind speed is much faster several metres above ground than it is just above the ground.

I think you're going to get a lot of people posting here wondering why they should do your homework for you...

[WoWo]

Don't be so hard on them Sasha13.

It's because lower down the wind is under the influence of gravity.

[heathfield]

More to do with the general roughness of the ground causing a drag effect than with gravity

[newtron]

I agree with heathfield. Roughness is most likley the answer.

[Robb Phoenix]

Friction of wind with the ground, nothing to do with gravity.

Hey, I wasn't being harsh... I was anticipating some other peoples answers...

so would you trust our answers for your home work? will we get the blame if we are wrong??!!

i think it has something to do with obstacles...buildings trees etc, although if the wind is blowing in the "right" direction these obstacles can also speed it up!!!
