THE ROYAL SOCIETY OF CANADA 



The Most Probable and Possible Extreme Gust Velocity 

 Derived from the Canadian Standard Anemometer 



If now the readings of the most probable and extreme maximum 

 velocities are calculated from the observations of the Canadian 

 anemometer after correcting it according to the equation 



y = l-24--25 log Vr 

 or from 



Va = Vr (1-24--25 log Vr) 

 where Va is the actual and Vy the recorded velocity, a most interest- 

 ing result is obtained as shown in Table VIII and Fig. 5.
