Writing from Australia Ian Wilson will be familiar to Talkshop regulars expounding his interest in astronomical connections with earth. He has three related recent articles and now a summary binding them together. Tim adds, the subject has a long history including false accusations of astrology by detractors; in this linked 1999 paper by a veteran scientist some of the origins and history is briefly mentioned and also that as data and computing power becomes available progress is being made. It mentions El Nino [paper see ref 1]. Strangers may need to get a conceptual understanding of the regular alignment of the earth moon and sun, where self evident effect on earth is the cyclic variation is ocean tidal height.

1. A SUMMARY OF THE THREE PREVIOUS POSTS
If you are unfamiliar with this topic you may wish to read the following three post in order to understand this current covering post.
- Evidence that El Nino Events are triggered by the Moon – I
I . The Changing Aspect of the Lunar Orbit and its
Impact Upon the Earth’s Length of Day (LOD).
- Evidence that El Nino Events are triggered by the Moon – II
II. Seasonal Peak Tides – The 31/62 year Perigee-Syzygy
- Evidence that El Nino Events are triggered by the Moon – III
III. Strong El Nino Events Between 1865 and 2014.
Observations of the Earth rate of spin (i.e. LOD) show that there are abrupt decreases in the Earth’s rotation rate of the order of a millisecond that take place roughly once every 13.7 days. These slow downs in spin occur whenever the oceanic (and atmospheric) tidal bulge is dragged across the Earth’s equator by the Moon. They are produced by the conservation of total angular momentum of the Earth, its oceans and its atmosphere.
