No, you are. Go ahead and claim increasing temperature doesn't increase SAP
Go ahead, explain how the same mass can exert varying pressure.

Speed up the molecules.... duh...
Would a 10 kg bar of metal on a scale push down on the scale more if it was hotter?
LOL!!!
No, but if you heat the air beneath it given the same force, you get more pressure...
From Google
Explanation: An increase in temperature increases the kinetic energy of the air molecules. An increase in kinetic energy cause an increase in the average speed and momentum of the air molecules. Molecules that are moving faster with more momentum collide with other molecules with more force creating more pressure.
The hotter 10 kg bar has faster molecules than the cooler 10 kg bar.
Why doesn't the scale show it weighs more?
Molecules that are moving faster with more momentum collide with other molecules with more force creating more pressure.
Not all the molecules in the gas column are moving down.
Babble.aka weather...
Center of a cane has low air pressure....
DUH...
70 years of dropping SAP.... that's not weather, that's...
NO INCREASE IN TEMPERATURE
NO ONGOING NET ICE MELT.... just the opposite
An enclosed plastic bottle is not the atmosphere non reader….No, they move in all directions.
Try this. Fill a plastic bottle with warm air, and put it in your freezer, and notice what happens....

That would mean some move up, reducing surface air pressure
You're not back on that "Earth's atmosphere is like a sealed bottle", are you?
Then go on record and state that YOU believe increasing atmospheric temperature would reduce surface air pressure...
Force constrained. Not sealed. But for surface air pressure, expanding the height of the atmosphere does nothing to change surface air pressure, but increasing temperature does.
Why would I claim that?
The height of the atmosphere isn't "force constrained".
LOL!!!!
Clearly, you won't claim that because you know it is clearly wrong....
A) yes it is, without gravity it would be unconstrained... not sealed or set at a specific height, but YES CONSTRAINED....
B) the height of the atmosphere is not the issue, the MASS of the GAS in the column above is, so if you heat the atmosphere and expand it, the force of gravity on that remains the same, while the temperature has increased (a separate issue from the force of mass and gravity) which causes SURFACE AIR PRESSURE to INCREASE
Show how it's "force constrained".
The mass that doesn't change is the issue? And?
Tropical countries have higher surface air pressure than temperate countries?
How fucking stupid is that question... What prevents the gas in the atmosphere from floating out into space?
Hence temperature changes do correlate with SAP....
That is likely correct....
What prevents the gas in the atmosphere from floating out into space?
What prevents it from expanding further into space?
That is likely correct....
Post your evidence.
a) GRAVITY....
b) you brought it up, you find the "evidence..."
Gravity doesn't keep it from expanding and contracting.
You want me to post evidence that warmer countries have higher SAP?
But that would help your claim, if true, why would I do that?
It'll be more convincing coming from you.
So go ahead.

Air pressure at ground level at the equator and the poles
At the equator at sea level you are about 17 miles higher up than at the poles ie 17 miles further from the center of the earth. Yet the air is not the same as it would be 17 miles up at a higherphysics.stackexchange.com
This one thinks there is either no difference or a very small one.
Does climate affect air pressure?
![]()
This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.

I guess you're right.
Surface air pressure is lower because the planet is warmer.
