From the foregoing table we obtain the following summary of results : — | 





Spring. 



Autumn. 



Winter. 



Average velocity of all winds in miles per hour 



Velocity in mean direction on the supposition th the winds from every point 



of the compass move with the foregoing average velocity .... 

 True velocity in mean direction, giving to the winds from the several points of 



the compass each their own average velocity, as shown in the table 

 Excess of the latter over the former
