This has been shown more clearly by grouping the winds together 

 according to their mean effect on atmospheric temperature. It was 

 found that the mean difference between the observed temperatures 

 and first-order curve temperatures for the whole year for 



1. E. wind (as defined above) was - 3' 1 F.

Seeing that the first three of these had a decided cooling effect, the 

 next two a very slight cooling effect, and the last three a decided 

 warming effect on the first order atmospheric temperature, these winds 

 were studied in three groups, which we will call the " cold," " tempe- 

 rate," and " warm," and temperature curves were drawn for each of 

 these groups (Diagram 4). Each of these three curves shows some
