Is atmosphere affected by tidal forces ? why?

I read that it effect all mass and large bodies of water, and liquid mantle. it’s just more noticeable on oceans. What about the atmosphere ? It has some mass hasn’t it ?

The atmosphere do have tides you can read about them at [https://en.wikipedia.org/wiki/Atmospheric_tide](https://en.wikipedia.org/wiki/Atmospheric_tide) I have not read it but is should describe the effects.

It is not just the fluid part of earth that have tides. It will have an effect on the solid part to. There is land tides on earth that can be 55cm https://en.wikipedia.org/wiki/Earth_tide

Yes it is, but the force is much weaker than the thermodynamic cycle caused by the temperature difference of day and night.

The moons gravity has a stronger effect on wind by the movement of the oceans displacing air than directly on the air since it’s density is so much lower. The pure gravitational effect is mostly noticable in the very high athmosphere, so far away from us.

Yes but it’s real subtle. The atmosphere has mass just like the oceans and will get pulled by the moon’s gravity. However, we live at the bottom of about a hundred miles deep ocean of air so the effect on us is very faint. Unlike the ocean tides where we can see and define the surface of the ocean, the atmosphere fades out gradually so we can’t mark the top of the atmosphere without scientific instruments and a lot of math.

Yes it does. Because the atmosphere is a gas mixture, and gas is made out of atoms, which have mass, and are thus affected by the gravity of the moon, which causes (the majority of) our tidal forces.

The mantle is solid (but plastic), not liquid. The mantle deforms elastically due to tidal effects caused by the Moon, which is part of what causes the Earth to not be a perfect sphere & may be relevant to the formation of mantle plumes (hotly debated)

The outer core behaves like a liquid (it’s a low-viscosity fluid that convects turbulently), but the level of tidal influence here is another argued-about planetary science thing, especially the relationship to the planet’s magnetic field. Some subscribe to the classic “geodynamo” hypothesis, but there’s an alt theory that most of the mag field is generated by “tidal eddies” in the fluid outer core. We do all tend to agree that tidal forces shear the fluid outer core into distinct sub-layers.

Think about it: the tides occur because the moon’s gravity tugs on the earth. All matter between the core of the earth and the moon feels this effect.

Solar effects dominate, but scientists have detected statistical effects from the lunar tide as well. https://www.sciencenews.org/article/atmospheric-tides-alter-rainfall-rate

Tl;Dr Tidal waves can carry wind because the air touching the water gets carried away causing , and that air is very cold during the night. While the sun pushes out solar winds and the mantle warms the ground making hot air.

Imagine the entire universe being covered in cheap Elmer’s glue straight off of the glue stick. So, for an experiment take two balls and put Elmer’s glue stick glue on it you can roll the ball and they will stay together, but if you suddenly and jarringly stop they unstick and one flies away. The ball you stopped it the tide, and the ball that went flying is the wind.

Now wind and all things are affected by a thing called centrifugal force. Centrifugal force is just like when you’re on a merry go round and you want to fly off of it. Well that is how wind works! all of the wind goes into the upper atmosphere to form Jetstreams and that why near the upper atmosphere your ears will pop with the atmosphere being a lot… more. Like how when you bring a deep sea fish to the surface is just melts

Sometimes some air will fly out of the atmosphere like that one kid who flew off the merry go round. Now solar wind also contributes to the atmosphere making things hotter. While the cold air from the ocean clashes with it, TORNADOS! Said Tornados or Hurricanes can drastically change the atmosphere because bringing in and removing air making it hot then cold then yes then no.
