The El Niños during New Moon Epoch 5 - 1963 to 1994


A detailed investigation of the precise alignments between the lunar synodic [lunar phase] cycle and the 31/62 year Perigee-Syzygy cycle between 1865 and 2014 shows that it naturally breaks up six 31 year epochs each of which has a distinctly different tidal property. The second 31 year interval starts with the precise alignment on the 15th of April 1870 with the subsequent epoch boundaries occurring every 31 years after that:

Epoch 1 - Prior to 15th April  1870
Epoch 2 - 15th April 1870 to 18th April 1901
Epoch 3 - 8th April 1901 to 20th April 1932
Epoch 4 - 20th April 1932 to 23rd April 1963
Epoch 5 - 23rd April 1963 to 25th April 1994
Epoch 6 - 25th April 1994 to 27th April 2025



The hypothesis that the 31/62 year seasonal tidal cycle plays a significant role in sequencing the triggering of El Niñevents leads one to reasonable expect that tidal effects for the following three epochs:

New Moon Epoch:
Epoch 1 - Prior to 15th April  1870
Epoch 3 - 8th April 1901 to 20th April 1932
Epoch 5 - 23rd April 1963 to 25th April 1994

[N.B. During these epochs, the peak seasonal tides are dominated by new moons that are    predominately in the northern hemisphere.]

should be noticeably different to its effects for these three epochs:

Full Moon Epochs:
Epoch 2 - 15th April 1870 to 18th April 1901
Epoch 4 - 20th April 1932 to 23rd April 1963
Epoch 6 - 25th April 1994 to 27th April 2025

[N.B. During these epochs. the peak seasonal tides are dominated by full moons that are predominately in the southern hemisphere.]
If we specifically look at the 31 year New Moon Epoch 5, we find that: 

Figures 1, 2, and 3 (below) show the Moon's distance from the Earth (in kilometres) at the times where it crosses the Earth's equator, for the years 1964 through to 1995.

Superimposed on each of these figures are the seven strong(#) El Niño events that occurred during this time period. Table 1 summaries the dates (i.e year and month) for start of each of these seven strong El Niño events.

[* N.B. The 1969 El Niño event just falls short of the selection criterion for a strong El Niño event because it only last for three months. It has been included in Table 1 for completeness.]

Figures 1,2 and 3 clearly show that all of the eight El Niño events in this tidal epoch occur at times where the distance of the Moon as sequential crossings of the Earth's equator have almost the same value of ~ 382,000 km. In the years when this happens, the lunar line-of-apse is closely aligned with either the December or June Solstice. 

It is possible that this correlation could be dismissed as a coincidence. However, it is extremely unlikely that:

a)  during the other New Moon tidal epoch i.e. Epoch 3 - from the 8th April 1901 to 20th April 1932, El Niño events should also occur when  the lunar line-of-apse is closely aligned with either the December or June Solstice.

b) during the Full Moon tidal epochs i.e. Epoch 2 - 15th April 1870 to 18th April 1901; Epoch 4 - 20th April 1932 to 23rd April 1963; Epoch 6 - 25th April 1994 to 27th April 2025, El Nino events should occur when  the lunar line-of-apse is closely aligned with either the March or September Equinox.

The switch between timing of El Niño events, once every 31 years, at the same time that there is a switch from a New Moon tidal epoch to Full Moon tidal epoch, tell us that it is very likely that El Niño events, are in fact, triggered by the lunar tides.

  1. Excellent paper. Brief, clear and the findings well defined. Please can you extend the latest graph out to 2020 and postulate future El Nino events.

  3. Ninderthana, This is a little off-topic. Cyclones in the NW of Australia now have an increased economic impact. (Disruption to high economic value LNG and Iron Ore operations). I see you have made predictions on various weather patterns like Victoria extreme rainfall and Adelaide/Melbourne high temperature. Are you able to detect long term cyclone patterns in your field of study? This would be very useful for risk management.

  4. Anon-2,

    This work may be able to predict the timing of Madden-Julian Oscillations which are the main weather features of the equatorial and near-equatorial regions of the pacific ocean. If this can be done, it may allow us to predict the rough severity and number of cyclones in any given summer season. However, there is still a long way to go yet.
