The Symmetrical Variation of Winter and Summer Air Temperature

[摘要] 1) Definition of winter an summer air temperatureThe author calculated the consecutive means of 6 pentads temperature in winter and summer, whose min. and max. are defined as the winter and the summer air temperature.2) ConclusionsThere exist some symmetrical variations in the secular variation of the winter and the summer temperature at Miyako, as shown in the attached Table.(a) The symmetrical variations occur successively, namely, when one march of symmetrical variation ends, then the next march begin.(b) The year of symmetry (point of symmetry) appears alternately in the manner such that, when a year of symmetry exists in the march of winter temperature variation, the next year of symmetry is found in the march of summer temperature variation.The above result can be applied to all the years investigated (65 years) at Miyako without exception, and will also be applicable to the other localities in Tohoku District, northern part of Japan Proper.
