WINDS OJb' THE GLOBE. 



FORCES THAT DEFLECT THE CLOUD CTTRRENT OF THE ATMOSPHERE 

 FROM ITS MEAN ANNUAL DIRECTION 



The annual direction oT the upper current, as indicated by the motion of the 

 clouds, shows — in the temperate zone — a great uniformity from the west. Of the 

 resultants given in the following table four-fifths are from points between west by 

 north and southwest. If those stations that lie within the limits of the polar 

 and equatorial systems of winds are excluded, the uniformity is almost without 

 an exception. The ratio, 42 per cent., is nearly double that of the surface 

 current (23 per cent.), thus showing a steadiness of motion admitting of little 

 monsoon influence. Accordingly we find, in the right-hand columns of the 

 following table, that the deflecting forces are usually quite small ; in fact, so small 

 that a map constructed on the same plan and scale as Plates 10, 11 and 12, 

 would not satisfactorily exhibit their direction or amount. For this reason they 

 are collected in the accompanying table. The yearly resultants are prefixed for 

 ready comparison.
