Wind and transpiration

I had a question today that I'm not quite sure I know the answer.  In 
connection with an assignment on the effects of various factors on 
transpiration a student suggested that at high wind velocities leaves would 
loose water rapidly due to the effect of low pressure above the stoma 
caused by the Venturi effect.  I have a feeling that such factors would not 
be too significant due to the small size of stoma and the movement of the 
leaves in wind.  Has anyone any thoughts on this.
