RELATIVE FREQUENCY AND STRENGTH OF WINDS KKHM VAKKM-S POINTS. 



Figs. 7 to 10 show the relative frequency of winds from each of sixteen points, combined with their 

 strength. The length of the single line indicates the percentage of light winds (forces 1 to 3 of Beaufort's 

 scale) observed from the point at which it is drawn ; the length of the double line similarly indicates the 

 percentage of moderate winds (forces 4 to 7 of Beaufort's scale), and that of the broad line that of gales 

 (force 8 and above) ; the total length of the line thus showing the frequency of all winds, irrespective of 

 force, from the point indicated. The figures are drawn for each month, and are grouped under the several 

 seasons. 



In the summer months light winds predominated, and gales are only shown in February, 190:3, the 

 month of arrival of the expedition at Winter Quarters. In the autumn months the wind force had 

 decidedly increased, and winds of moderate strength were upon the whole more common than light winds; 

 gales were somewhat frequent in March, 1902, but in that month only. Moderate forces were, upon the 

 whole, more frequent than light winds in the winter months, and gale forces were comparatively frequent, 

 especially from southerly points. In the spring months there were not many gales recorded, but winds of 

 moderate force were very common.

in Miles per Hour by the Cup Anemometer. 



From the figures given in Table XIV. it would appear that, on the whole, the southerly winds were 

 stronger than those experienced from any other quarter, south-south-west winds giving for the whole
