directly transferred to the tables (here converted into feet per 

 second). 



The monthly means vary between 1"9 metres (6 "2 feet) in May, 

 and 5' 5 metres (18 feet) in October; the mean for the whole ten 

 months is 3'4 metres (11 '1 feet) per second. These velocities may 

 be characterized as surprisingly small; and the number of stormy 

 days agrees with this low velocity. Their number for the whole 

 period is only 11, fairly evenly divided between the months; there 

 are, however, five stormy days in succession in the spring months 

 October and November. 



The frequency of the various directions of the wind has been 

 added up for each month, and gives the same characteristic 

 distribution throughout the whole period. As a mean we have the 

 following table, where the figures give the percentage of the total 

 number of wind observations: 



Almost every third direction is E., next to which come S.W. 

 and S. Real S.E., on the other hand, occurs comparatively rarely. 

 Of N., N.W., and W. there is hardly anything. It may be interest- 

 ing to see what the distribution is when only high winds are taken 

 into account — that is, winds with a velocity of 10 metres (32 8 feet) 

 per second or more. We then have the following table of per- 

 centages: 



N. N.E. E. S.E. S. S.W. W. N.W. 

 7 12 51 10 4 10 2 4 



Here again, E. is predominant, as half the high winds come 

 from this quarter. W. and N.W. together have only 6 per 

 cent. 



The total number of high winds is 51, or 5*6 per cent, of the 

 total of wind observations. 



The most frequent directions of storms are also E. and N.E.
