296 RESULTS OF I'HE METEOROLOGICAL OBSERVATIONS TAKEN DURING 



Force of the Wixd. 

 The force of the wind is shown on the usual Beaufort scale of to 12 : — 



Hence the stormiest wind is the S.W., blowing with a mean force of 5"0, while 

 the S.E. wind is the lightest, with a force of 3 '6, there being roughlj' a difference 

 of about 10 miles per hour between these two directions. In Spring, Summer, and 

 Winter the stormiest wind is the S.AV. and the calmest S.E., but in Autumn 

 the directions are N.E. and E. respectively. At all seasons except Autumn the 

 force of the S. wind is considerably below that of the S.W., but at this season it is 

 slightly above it. 



The departures honi the seasonal means are shown in the subjoined table : — 



N.W. and S.E. winds at all seasons of the year are below the general average wind 

 force for the season, while S.W. winds are above it. N.E. winds, it will be seen, ap- 

 proximate to the normal strength in Spring, are a little below it in Summer, while in 

 Autumn and Winter they ai'e considerably in excess of the general average. 



Amount of Cloud. 

 The mean amount of cloud, overcast sky, or fog = to 10 is as follows :-
