<strong>Weather</strong> <strong>By</strong> <strong>The</strong> <strong>Moon</strong><br />
of-mass of the Earth and <strong>Moon</strong>. However, at local points<br />
on, above, or within the Earth, these two forces of mutual<br />
planetary attraction are not in equilibrium, and oceanic,<br />
atmospheric, and Earth tides are the result.<br />
ALL TIDES<br />
All the tides are caused by different strengths of the<br />
<strong>Moon</strong>’s gravity at different points on the Earth. <strong>The</strong> side of<br />
the Earth facing the <strong>Moon</strong> is about 4000 miles closer to<br />
the <strong>Moon</strong> than the center of the Earth is, and the <strong>Moon</strong>’s<br />
gravity pulls on the near side of the Earth more strongly<br />
than on the Earth’s center. This produces a tidal Earth bulge<br />
on the side of the Earth facing the <strong>Moon</strong>. <strong>The</strong> Earth rock is<br />
not perfectly rigid; the side facing the <strong>Moon</strong> responds by<br />
rising toward the <strong>Moon</strong> by a few inches on the near side.<br />
Estimates have ranged from 6-12 inches for the Earth Tide.<br />
<strong>The</strong> notion that the land beneath your feet, with you on it,<br />
rises a few inches to meet the moon as it passes overhead<br />
each day is hard to accept, as we have nothing to compare<br />
the vertical movement to.<br />
<strong>The</strong> Sun and <strong>Moon</strong> pull on everything, and the resultant<br />
directions of those separate (and at New moon times,<br />
combined) pulls depend on the massse of what is being<br />
pulled. <strong>The</strong> more fluid seawater responds quicker than the<br />
land, and the air responds quicker than the sea. <strong>The</strong>re is a<br />
bulge of water continually underneath the transitting moon<br />
which produces the ocean tides, but also a larger and quicker<br />
bulge of air and a smaller and slower bulge of land.<br />
Whilst a known high sea tide is on the moon’s side of<br />
the earth, it has often been speculated upon as to why there<br />
