<DIV>OK. I understand fully the declination, heck I live below the tropic
of Cancer so get to experience the Lahaina Noon phenomenon. I also
understand sun angle above the horizon but that’s not what the original comment
was about. It was about the *difference* between winter and summer sun
angles relative to a high latitude point on the globe and my argument is that it
is the same everywhere, i.e. 47 degrees difference between the low N/S point of
the sun at noon versus the high N/S point at noon. That doesn’t
change. At one latitude the sun may “bottom out” at 12 degrees above the
horizon and at another it may bottom out at 40 degrees above the horizon but the
difference between that the top point at each latitude is still 47
degrees.</DIV>

<DIV>At noon LST the sun is latitude angle from Zenith, the solar declination is
23.5 degrees and the sun on the solstices is above and below the equinox

varies and the sunset angle varies depending upon latitude.

<DIV>Hmmm, I guess there could be a factor that enters into it due to the
curvature of the earth but the difference between the tropics of Cancer and
Capricorn, the extent of relative solar movement, is 47 degrees and that’s not
about to change.</DIV>

Explain this one to me please. The difference between winter solstice and
summer solstice sun angle is 47 degrees, everywhere on the planet, even in
Hawaii. I suspect that in higher latitudes a lower sun angle means more
atmosphere to affect insolation but the planet, last time I checked, is tilted
the same everywhere.</SPAN><SPAN
