Can the Moon change our climate? Can tides in the atmosphere solve the mystery of ENSO?

The Moon has such a big effect — moving 70% of the matter on the Earth’s surface every day, that it seems like the bleeding obvious to suggest that just maybe, it also affects the air, the wind, and causes atmospheric tides. Yet the climate models assume the effect is zero or close to it.

Indeed, it seems so obvious, it’s a “surely they have studied this before” moment. Though, as you’ll see, the reason lunar effects may have been ignored is not just “lunar-politics” and a lack of funding, but because it’s also seriously complex. Keep your brain engaged…

Ian Wilson and Nikolay Sidorenkov have published a provocative paper, Long-Term Lunar Atmospheric Tides in the Southern Hemisphere. It’s an epic effort of 14,000 words and a gallery of graphs. As these atmospheric tides swirl around the planet they appear to be creating standing waves of abnormal air-pressure that slowly circle the planet, once every 18 years. If this is right, then it could be the key to finally understanding, and one day predicting, the mysterious Pacific ENSO pattern that so affects the global climate. Even at this early stage, brave predictions are on […]

The Moons’ influence on the atmosphere over Australia

We know the moon changes our tides, but can it also change our rainfall? Could the moon also cause tides in the atmosphere? Some researchers have found such periodic movements in air above 3000m. Some have suggested that the moon drives the cyclical shifts in the Length of Day (LOD) that occur on a fortnightly and seasonal basis.

Ian Wilson has been scouring the data quietly for years, following these ideas, and has found a link between lunar cycles and the sub tropical high pressure ridge that occurs in summer over the East Coast of Australia. He noticed there were 9.4 and 3.8 year cycles which match periods in spring tidal cycles. What matters is how close the full moon is to perhelion (the closest point Earth comes to the Sun). It’s yet another piece of the puzzle that the IPCC favoured models ignore.

The lunar forces are, not surprisingly, smaller than the solar one, and as the abstract points out: “it is not so much in what years do the lunar tides reach their maximum strength, but whether or not there are peaks in the strength of the lunar tides that re-occur at the same time within the annual […]
