Since heat rises, it is logical to assume that the air would heat up as well. This is why it is always warmer and more difficult to breath in heated indoor pools but when you get closer to the ground, it gets cooler and easier to breath. The warm air and humidity went up and the cold air went down.
The weight of the air on Earth's surface is approximately 14.7 pounds per square inch (psi), or 101.3 kilopascals (kPa). This pressure is due to the force exerted by the column of air above us, known as atmospheric pressure.

When surface air is significantly warmer than the air above it
Away from the poles because the air near Earths surface is warm.
When air at the surface diverges, the airflow above typically converges. This process occurs due to the conservation of mass in the atmosphere; as air spreads out horizontally at the surface, it creates a vacuum that draws in air from above, leading to upward vertical motion. This upward movement can enhance cloud formation and precipitation, particularly in areas of low pressure.
The air is thinner the higher you go.

The layer of air above the Earth's surface is called the atmosphere. It is composed of various gases and extends several kilometers into space.
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Because there is more air (which has weight) above you if you are around sea level. If you fly up, or climb a mountain, there is less air above you, therefore less air pressure.
because its hard to breathe thin air above earths surface, the higher you go its hard to breathe oxygen.
If the Earth's surface is cold, it will lead to cooling of the air above it due to direct contact and heat transfer. The cold surface will cause the air above it to become cooler, which can affect weather patterns, lead to the formation of fog or dew, and impact temperature gradients in the atmosphere.
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
how does air above cold surface move
The planet with an atmospheric pressure similar to that 30 km above Earth's surface is Venus. At an altitude of about 50 km above Venus, the atmospheric pressure is comparable to Earth's surface pressure.
