ON THE METEOROLOGY OF IRELAM). f 'J07 



From the foregoing numbers it appears, that high winds are 

 much more frequent on the western than on the eastern coast, the 

 numbers denoting the relative frequency, on the average of the 

 entire year, being nearly as 3 to 1. This preponderance of high 

 winds on the western coast holds at all seasons of the year, the 

 maximum occurring at the north-western extremity in autumn, and 

 at the south-western in winter. The greatest frequency is in the 

 north-west, on the average of the entire year. 



The following are the cases in which the mean force of the 

 wind, over the whole island, amounted to a gale ; or in which the 

 mean velocity was 45 feet per second and upwards : 



Nov. 23, 24, 1850. Storm along the western coast, blowing at 

 first from S. S. W., and veering through S.W. to W. Least pressure 

 in north-west throughout. 



Nov. 23, 9 p. M. Storm began at south-western extremity of the 

 island ; velocity = 45 feet per second. 



Nov. 24, 9 A. M. Wind continued to blow in same district ; 

 velocity increased to 60 feet per second. Absolute barometric mi- 

 nimum (north-west) = 28*644. 



Nov. 24, 9 P. M. Storm extended over whole of western coast ; 

 velocity of wind = 55 feet per second. 



Dec. 14. Storm affecting the whole island, but chiefly the 

 western coast. Wind at first from S. S. W., but veering to W. S.W. 

 at 9 p. M. Least pressure in north-west throughout. Electrical 

 disturbance over the whole island. 



Dec. 14, 9 A. M. Velocity on western coast = 65 feet per 

 second. Absolute barometric minimum (north-west) = 28*952. 



Dec. 14, 9 P. M. Velocity on western coast = 50 feet per 

 second. 



Dec. 31, Jan. 1, 1851. Storm from S. W. and S., beginning 

 on western coast, and extending over the whole island. 



Dec. 31, 9 A.M. Velocity on western coast = 50 feet per 

 second. Direction S. S. W. and S. W. 



Dec. 31, 9 P.M. Gale affecting the whole island, except north- 

 eastern extremity. Greatest in south-west ; velocity = 60 feet per 

 second. Direction as before. Absolute barometric minimum 

 (north) = 29177.
