Figure 16: Depiction of the moon’s declination syzygy cycle at 20 to 28 degrees north latitude (upper right), then in the southern hemisphere high declination phase 20-28 degrees below the equator approximately 4-years later (lower right). As the earth rotates on its 24-hour cycle, gravitational force of the moon causes the oceans to bulge along the lunar gravitational envelope, and a dome of water to form on both sides of the earth.

The moon on the other hand reaches its highest declinations every 4 years instead of annually. Unlike the sun, the highest declinations of the moon vary from as little as 18 degrees to as much as 28 degrees. The highest of these declinations cyclically occur every 18.5 years, and the lower value 9 years before, or 9 years after this cycle.
These cyclical orbital patterns of the earth and moon in conjunction with the sun sets up very specific and powerful long-term recurring cycles that over time cause displacement of regional semi-permanent anticyclones (high pressure centers), and changes in regional and global climate. As mentioned earlier and will be discussed and demonstrated in upcoming sections, some of the most important and powerful Earth-Moon-Sun Syzygy alignments are the approximate 4-year cycle, 9-year, 18.5-year, 72-year, 231-year, 231-year, 925-year, 5000-year, 116,000-year and 460,000-year cycles, all of which are Primary Forcing Mechanisms (PFM) of the climate.
Chapter 7 provides PFM graphs prepared solely by Mr. Dilley of GWO, and an in depth analysis of these lunar cycles to global warming and cooling cycles from 460,000 years before present, to 100 or more years into the future.
