I've been thinking of this but I figured the start/end of seasons make a lot of sense if you think about the effect the length of days has on temperature. Essentially the length of days effects the rate of energy added by the system. For instance days are longest on June 21st but temperatures will generally keep increasing until August. It's a bit like taking that sinusoid and integrating it resulting in a cosine shifted by a quarter of a phase. |
