Sparser (yearly, not monthly) records, obtained over a century at different latitudes in Japan, demonstrate that the decadal components are not consistent in moving spectra of original (as yet not detrended) data. Longer and denser series over much greater differences in latitudes and longitudes will have to be subjected to a much more thorough scrutiny, in conjunction with a series of possibly pertinent variables, to assess the contributions of different sources of variation in different areas of Japan and world wide, preferably in democratic, non-combatant areas, where the socio-economical, political and other war-associated conditions are mostly in the background. 收起
