COMPUTATION OF HOURLY BAROMETRIC EFFECTS. 



To secure a basis for computing the hourly barometric effects at a gage 

 station, one must first compute the lag in each component of the barometric 

 effect by the use of table No. 2, page 22, and compute the values of C w and 

 C n by formulae (36), (37), (38), and (39) of page 23. 



At Milwaukee these computations were made from the values shown in 

 table No. 6.
