WIND. 



287 



The constancy or steadiness of the wind direction reaches almost 50 

 per cent. The veering with the sun is nearly as frequent as the backing 

 against the sun. 



The veering and the backing are fairly evenly distributed in all months 

 over the whole wind-rose. I have not been able to h'nd any preponderating 

 tendency in the veering or backing to keep distinctly to certain rhumbs of 

 the compass. 



On the other hand the winds with the greatest steadiness show a remark- 

 able correspondence with the prevailing winds. Taking out (1) the most fre- 

 quent direction of the wind from the Table, pages 280 and 281, (2) the dominant 

 wind-direction of the windward side of the wind-rose Table, pages 284 and 

 285, (3) the resultant wind from the Table given at the end of this chapter, 

 and (4) the wind of the greatest (and sometimes next greatest) constancy, 

 we obtain the following Table.
