So how do I explain that?
-
Herself has discovered - I blame Google - that today is Perihelion, and that we are over 5,000,000km closer to the sun than we were last July. She has also noticed that it is in fact bl**dy freezing round here and that it wasn't last summer. :sigh: Now I know it's that the axis of rotation is not perpendicular to our rotation round the sun and that the tilt of a tiny (13,000km) object affects the temperature more than being 5,000,000km closer to a huge ball of fire, but ... how do I explain that to her? When she is cold, she moves closer to the heat, not leans over a tiny bit! :laugh:

The difference between aphelion and perihelion is only about 3.4% On that basis She should expect to get warmer when she breathes in deeply. (If she's facing the fire her front parts will get about that much closer when she breathes in.) Of course, it would help if she breathed in and out slowly, for six months each.

Ah, yes - my favourite topic! Happy new arbitrary-period-of-time-close-to-but-not-quite-one-year-from-the-entirely-arbitrary-date-when-this-was-last-celebrated to one and all! We should really celebrate the tropical year, the sidereal year or the anomalistic year - these can be calculated precisely. Let's face it - so the earth nearly - but not quite - went around the sun once from an entirely arbitrary position, both astronomically and calendrically. The earth actually needs to spin another two quarter days to get to where it was (roughly) since the last leap year. Sidereal year = 365 d 6 h 9 min 9.76 s Tropical year = 365 d 5 h 48 min 45 s Anomalistic year = 365 d 6 h 13 min 52.6 s As a result of all this arbitrary nonsense, I now celebrate perihelion day. This morning I toasted in the new year with a bacon buttie and a large bloody Mary, at 07:20 local time (GMT +2). Next year, the UK can join in without getting up at sparrowfart, as perihelion occurs nearly two and a half hours later. So happy REAL new year to one and all. :cool: :laugh:

The buttie sounds good, but that's a little early in the day for me to start drinking vodka. At least, I hope you were referring to the cocktail? What was your wife's name again ... :~

As Phil said, the difference between perihelion and aphelion is only ~3.4%, so that isn't the cause of the difference. The difference is due to the fact that the Sun is (a) lower in the sky now than it was in July, and (b) appears for fewer hours in the day. Both these phenomena are due to the Earth's axial tilt. If the Sun is directly overhead (which can never happen in Wales) on a cloudless, clear day, you will get the maximum possible amount of light & heat. When the Sun reaches a maximum height of ~60 degrees above the horizon, which is what you get in June, then the amount of light and heat is only ~86% of the maximum possible. When the Sun reaches a maximum height of ~15 degrees above the horizon, which is what you get in December, then the amount of light and heat is only ~24% of the maximum possible. The effect of having Perihelion close to the winter solstice is to slightly moderate the cold of winter in the Northern hemisphere. A similar effect, moderating the heat of summer, occurs at aphelion. Note that the actual effects of less sun are moderated due to the gulf stream, the winds in the atmosphere, etc. etc.

Just point out that she's in Wales.
