PRECIPITATION AND THE STORM-CENTRE. 



BY S. A. MAXWELL, MORRISON, ILL. 



In a former article to the Review, I attempted to show the relative positions 

 of the storm-centre and the locality of tornadoes. In the ten instances of torna- 

 does there cited, all occurring in 1878, every one was found to be developed on 

 the equatorial, or right-hand side of the path of minimum pressure. My investi- 

 gations at that time led me to beUeve that other storms, besides tornadoes, had 

 similar relations to the storm-centre. 



Inasmuch as winds almost invariably blow toward the storm-centre, and the 

 warm winds are the generators of rain, I came to the conclusion that the locali- 

 ties of greatest rain-fall would be found to the south of the track of "low." I 

 constructed the following table to prove the truth of this conclusion. The table, 

 made out from the Signal Service Weather Map for August, 1878, shows the
