How is the moons declinations control our weather?
Lunar maximums have played a major role in the earth's weather, and in some of the most devastating storms in history. It is a the functional player when it comes to gravitational influence, and pulls/pushes on the elements. It raises the sea tides, earth-tides, and air-tides - raising the atmosphere when above the horizon, and lowering it when it sets below. The Sun, and the planets play a geomagnetic role, and the Moon, a much more gravitational role.
When at maximum north, or southern declination, and at specific apogee or perigee cycles, the Moon plays an even greater role when it comes to unstable weather. This has been known by classical astrologers for thousands of years, and recorded with centuries of observations.
The Weather is what happens when atmospheric tides are gravitationally pulled around by the Moon. The atmosphere is a mass of gas weighing five million billion tons. Just like the ocean-tide, every day the atmospheric-tide comes "in" and then goes "out".
More like higher and lower, with a stretched atmosphere extending higher into the heavens when the air-tide is in, and coming lower towards Earth ground level when the air- tide is out.
The
Moon has about one sixth - 1/6 - of the Earth’s gravitational force. From only a couple of hundred thousand miles away, changes in the Moon's orbital patterns have major effects on Earth. Between a third and a quarter the size of Earth, the Moon orbits in a strange 8 pattern - reaching maximum declinations to the north and south every two weeks.
Simply stated, changes in the Moon’s movement can trigger changes in our weather. How it works is rather logical, but conventional scientists seem to have a vested interest in not stating it, nor teaching it in meterological schools.
Meteorologists utilise sea level or sea surface temperature analysis as tools in forecasting. Astrometeorologists know that sea tides/levels/temps are affected by many lunar factors, including
synodic cycle, apsidal cycle(perigee/apogee), apsidal angle, declination angle, declination hemisphere, inclination, nodal or nutation cycle, apsidal cycle, anaomalistic cycle, tide cycle, variable diurnalism, moon’s angular momentum crossing ecliptic and equator, tide times and other cycles within cycles - it is very difficult to see just how conventional meteorologists can rule out the Moon as an empirical variable?
And, this is not even mentioning secondary factors such as wind speed and force, high and low pressure zones, cycles of currents, land movement etc. By virtue of tides and gravitational pull the Moon has its stamp on anything to do with the oceans.
It is a known fact that there are at least four separate but sometimes interfacing tides caused by lunar gravitation. The best known is the sea-tide, the exact times of which repeat every so many weeks, months and years. There is also the inner-core tide affecting the molten core of the Earth (Core Tide) which plays a major role in the cycles
of earthquakes and eruptions, the land-tide (called Earth-tide, where the ground rises towards the Moon about 8 inches per day as the Moon goes overhead and then recedes again when the Moon goes below the horizon) and the air-tide affecting the height of the atmosphere.
At only ten earth-circumferences away the Moon is very close, actually it is our closest celestial neighbour, and it has two-and-a-half times the gravitational pull of the Sun. Therefore it exerts an influence on everything movable on our planet, be it solid, liquid or gas. Much of this influence is barely noticeable because there is nothing to compare it too, like the rising of the land towards the transiting Moon, called the Earth Tide, and the receding of it back again within 24 hours.
If the Moon has an effect on the sea then it
must control the tides by distribution of the water. So is it silly to state that if it has an effect on the atmosphere then it must control the weather by distribution of the clouds?
Why should clouds, air, land and inner mantle not be tidal? They too, are masses of flexible matter. As masses they are subject to the pull of a large gravitational body such as a close Moon. The movable fluids on Earth would like to fly off into space toward the Moon, but are more strongly held to Earth by the Earth’s gravity and so remain on the Earth’s surface. But the inconstant transits of the Moon causes these fluids to be in flux.
One can liken the atmosphere to a fat rubberband; the top of which can stretch toward the Moon as the Moon goes overhead and then unstretch again when the Moon goes below the horizon. Because the weight of a rubberband remains constant either stretched or at rest, the
Barometer, which only measures the
weight of the atmosphere, cannot detect when the atmosphere changes height. This is why a barometer will seem to stay the same, even though the weather might change.
Atmospheric tides were researched in 1807 and rediscovered by British scientists Appleton and Weekes in 1939, who were investigating the strange phenomenon that shortwave radio signals reached around the world more clearly at New and Full Moon phases. They concluded if the atmosphere (or ‘stratosphere’) made radiowaves change clarity because of the phase of the Moon, then there must be a tidal effect in the air. There are scientific measurements of the atmospheric tide attributable to the Moon.
Whenever the Moon is above the horizon it has two bulges beneath it. These are pulled by gravitational attraction. One is made of
water and the other is a bulge of
air. The everchanging replacement of the water bulge results in the sea tide and the replacement of air within the air bulge results in the weather.
When the Moon is above the horizon, it is stretching the air and attracting, by gravitational pull, more atmosphere to higher levels in the sky - creating a larger volumed gaseous environment. The atmosphere is now a fraction higher and the amount can be up to 25% between phases.
The highest it gets is on a Full Moon night. If the useful atmosphere is 5 miles thick, then this stretch could be 1.25 miles, or for an accepted total depth of atmosphere of 60 miles, the atmospheric-tidal difference between high and low could be up to 15 miles.
The result of a higher atmosphere is to keep the cold of space further away from Earth. When the air height is lower because the Moon has set below the horizon and takes the air bulge with it, the cold of space creeps closer to the Earth, and the
subsequent drop in temperature can cause clouds to condense at this time. That will happen during the day of a Full moon, and this is why it often clouds up on that day around noon-time.
When the Moon is below the horizon it is more likely to
rain. If no rain happens, temperatures will most likely drop. Very often rain will also fall an hour or so on either side of the Moon setting. At New Moon, when the Moon is overhead during the day, rain is less likely - but rain is more likely at night at this phase. In contrast, at Full Moon, the nights will nearly always be clear. Old mariners used to have nautical saying: "the Full Moon eats clouds."
