TEMPERATURES AND SUN S RADIATION ABBOT 



2. Since greater causes generally produce larger effects, excep- 

 tionally wide ranges of solar variation should be associated with larger 

 temperature ranges than the average of all the cases. 



3. Since similar causes generally produce similar effects, the aver- 

 age results found in the years 1924 to 1930 should closely resemble

SOLAR VARIATION AND TEMPERATURE DEPARTURES AT WASHINGTON 



Fig. 2. — Oppositeness of temperature departures at Washington which follow 

 average rising and falling sequences of solar variation. 



in phases, though not necessarily in amplitudes, the average results 

 found in the years 1931 to 1935. 



4. Since the sun shines on the whole earth, temperature effects 

 which fulfill criteria i, 2, 3 should be found at all stations. 



I will give first the results obtained with Washington tempera- 

 tures. Figure 2 will show to what a high degree criterion no. i is
