304 METEOROLOGICAL REPORT, 18G6, 



WIND. 



The returns which have been furnished to the Club, of the 

 direction of the wind, are again exceedingly scanty. So easy 

 and simple a matter as making a daily note of its direction ought 

 not to present much difficulty to many members of the Tyrieside 

 Club. 



The observations most needed are those taken from wind vanes 

 placed in elevated situations, and as far as possible out of the 

 influence of merely local currents. 



A comparison of the few returns obtained by the Club in this 

 and previous years, with the following deductions obtained by 

 Mr. Glaisher, from twenty years recorded observations at Green- 

 wich Observatory, will be interesting. 



According to Mr. Grlaisher's observations : — 

 The north wind is least prevalent in December, and most pre- 

 valent in May. 



The north-east wind is least prevalent in December, and most 

 prevalent in May. 



The east wind is least prevalent in January, and most preva- 

 lent in April. 



The south-east wind is least prevalent in July, and most pre- 

 valent in March. 



The south-west wind is least prevalent in April, and most pre- 

 valent in July and August. 



The west wind is least prevalent in May and November, and 

 most prevalent in October. 



The north-west wind is least prevalent in May, and most pre- 

 valent in March. 



Calm days are least frequent in April, and most frequent in 

 September.
