difference remarkable between the winter months and the summer 

 months, when the variations run on the whole oppositely to one 

 another. On these grounds the curve for the entire year (J) shows 

 relatively small fluctuations, since the variations in the different 

 parts of the year go in opposition. But it is remarkable that even 

 within the winter months the variations do not simultaneously agree. 



Figure 83. Anomalies of the air temperature in the interior of Asia for 

 each month of the year (I to XII), for the three winter months (W), for 

 the three summer months (SO), and for the whole year (J). P: prominences 

 according to the observations in Rome and Catania. S : sun spots. All the 

 curves are smoothed according to the formula fe=Ho + 2& + c). 



For example, the variations in February and partially also those 

 in March tend to go oppositely to the variations in January and 

 also in December and partly even in November. 



Taking now these temperature curves for different months to- 

 gether with the curve for the prominences and sun spots (curves P 

 and S at the bottom of the figure), we find that in the first sun spot
