You might call it an inverse oriel ;-)

Every time I see the explanation which has 366 rotations in 365 days
it makes me shake my head,I wonder what happens when they encounter
the leap year from Mar 1st 2011 until Feb 29th 2012 which have 366
days in it ! -

So we have a Harvard/NASA explanation while the center of discussion
here is daily temperature fluctuations which would occur within a 24
period where local influences dominate the normal response of
temperature rises and falls due to the rotation of the Earth 1461
times across 4 years.

No offence,you would have to be a bunch of dummies to go along with
366 rotations in 365 days and I am not talking about the ability to
remain silent,if anger or intense irritation is not present then there
must be tumbleweeds going through your minds.

Anyone want to predict that temperatures will fall and rise within the
next 24 hours and the cause behind it ?,I wouldn't count on the NASA/
Harvard explanation which is merely an extension of the one that was
conceived in the late 17th century U.K..



Perhaps I've missed something here. The Earth does rotate on its axis 366
times in 365 days. Because of the fortuitous fact that the Earth rotates on
its axis in the same sense that it revolves round the Sun (i.e.
anti-clockwise when viewed from above the North Pole), it has to turn a tiny
bit more than 360 degrees to bring the Sun on to the meridian each day.
Rotating through this extra very small angle takes approximately 4 minutes.
365 times 4 minutes = approximately 1 day (approximately because the 4
minutes is approximate), hence the small daily extra rotation amounts to a
whole revolution at the end of a year. If you want to talk about 366 days,
then the Earth will have rotated 367 times (+ the tiny amount!). Or is this
what everyone has been saying? As I said, I may have missed something.
Actually it's not quite correct to say that the Earth rotates on its axis
every 24 hours - it's 23 hours and 56 minutes, and the 4 minutes makes it up
to 24 hours.
