OPPOSING SOLAR TRENDS 



Number 11 — Important opposed trends in solar variation^ 



The A. P.O. at Washington devoted much effort after 1942 to 

 studying such upward and downward trends in solar variation as are 

 shown in figure 46, Pub. 4545,^ not here reproduced. It was 

 found that the temperature in Washington and several other United 

 States and European cities responded to these solar trends by long- 

 lasting marches, opposed like right and left hands. So many papers 

 have been published on this observation that it seems superfluous 

 to bring more evidence here. Figures 46, 47, and 49, and pages 52 to 

 57 of the text of Pub. 4545 ^ show that large opposed temperature 

 changes occurred simultaneously in Europe as well as in the United 

 States in response to over 300 cases of such opposite solar trends. (See 

 fig. 45, Pub. 4545^.) Pub. 3771 ^ presents a long investigation of the 

 subject. It ends with a summary containing 18 sections. Not only 

 solar constant measures, but solar faculae, calcium flocculi, and iono- 

 spheric phenomena act as triggers to set off these opposed long- 

 continued large temperature variations. 



In Pub. 4462 ^ of 1961 it is suggested that much better solar con- 

 stant measures could be made from earth satellites than from moun- 

 tains, because the atmosphere would be eliminated. If that were done, 

 forecasts of detailed world temperature, depending on trends of solar 

 variation, could be obtained covering 16 to 20 days in advance con- 

 tinuously. (The above cited fig. 49 of Pub. 4545 ^ is given originally 

 in Pub. 4462.^) 



TERRESTRIAL WEATHER 



Number 10 — Harmonic periods and long-range forecasts. 



We now come to the important claim of a harmonic family in 

 weather changes identical in periods with such a family in solar varia- 

 tion, but showing far more percentage change in weather than in 

 solar variation. Even more obnoxious to meteorologists has been the 

 claim that useful weather predictions can be made from knowledge 



'' I insert Ntimber 11 before Number 10, because Number 10 is potentially our 

 most important discovery, requiring extensive comment and deserving the most 

 emphatic place of all our discoveries.
