DISCUSSION AND ANALYSIS OF THE WINDS. 675 



It is seen from the foregoing that in Western Europe, on the Atlantic Ocean and 

 in a certain region of the United States, the mean direction of the wind in the 

 year, summer and winter, is between S. W. and W. S. W., and the difference be- 

 tween the two seasons very small. If the rate of annual resultant is not greater, 

 it is because at all seasons there are many winds coming from other directions than 

 the prevailing one. 



In Pekin and Hakodade the mean annual direction is nearly the same as at 

 the above named places, but the ratio of resultant is small for another reason : 

 the winds of summer and winter being nearly opposite to one another, the resulting 

 annual movement is small. Yet at each of the seasons the winds are very steady. 

 The angle between the mean direction of the wind in winter and summer is 142° 

 at Pekin, and 133° at Hakodade, or more than f of a circle, and only from 3° 

 to 20° at the above cited places of Europe and America. Again, the mean annual 

 direction of the wind and ratio of resultant, in Southern India and Ceylon, are very 

 similar to those observed in Europe, but the mean direction of winter and summer 

 nearly opposite to one another, with an extremely great ratio at both seasons, there 

 are conditions as dissimilar as possible to those of Western Europe. 



In the pages which follow, the results to be drawn from the observations on the 

 wijids are considered by geographical divisions.
