• #### On the sun, moon and tides...(Score:1)

The mathematician is Ken Ring - his site is at http://www.predictweather.com/ [predictweather.com], and he mentioned the 1833 earthquake in his December 29, 2004 e-zine [topica.com]. 1833 + 19 * 9 is indeed 2004.

Turns out I misinterpreted what Ken said... the moon is actually 1/80th the mass of the earth, not 1 tenth, and the gravitation effect thing is a net measurement of the effects on the ocean. The reasoning is that because the tides are predominantly affected by the moon and not the Sun, that the net force created by the moon must

You mean?

the sun exerts about 100 times the gravitational
force compared with the moon. Yet we do not see
a solar tide 100 times the size of the tide
from the moon.

The solar tide is what we see with spring and
neap tides, I think. Spring tides are higher and
lower than neap tides, because the moon is new or
full.

But how do we separate out the variation in water
movement due to the moon and that due to the sun?

Some places only have one large tide a day. Like
the gulf between China and Korea. Also in Taiwan?

And for places that have 2 tides, why at the new
moon don't we get one tide instead when the water
rushes all to one side attracted by the moon and
sun together? Why does the water hang out on the
back side, away from both the sun and the moon? I
guess there is some sort of jello quivering going
on.

The changes in the air are changes in pressure. I
don't think there are changes in water pressure
with tidal movement, are there?

Anyway, the moon's affect on the weather: Food for
thought.
