Table XXIII. Monthly Means of the Force of the Wind. 



The lowest line of the preceding Table contains the mean results of all the 

 stations, or the average forces of the wind in the several months for the whole 

 island. The mean force for the entire year is 176, corresponding to a velo- 

 city of 20'4 feet per second. The force is, of course, greater in winter than 

 in summer, the mean force for the winter half year being 1'87, and that for the 

 summer half-year 1-65. The law of the annual progression is, however, greatly 

 masked by irregularities; thus, the minimum force for the year 1851 occurs 

 in the month of September, while the force in June is above the average of 

 the entire year. 



In the following Table are given the results of the preceding for the entire 

 year, and for its two principal divisions. The excess of the force in winter 

 appears at all the stations, excepting Dublin, Portarlington, and Athy.* At 

 these three stations, also, the force of the wind is much below the average. 



* Buncrana is likewise an exceptional case ; but the exception is there probably due to 

 inaccuracy of observation.
