The atmosphere has lower heat capacity
The relationship between air temperature and its capacity to hold water vapor is governed by the principle that warmer air can hold more moisture than cooler air. As the temperature increases, the kinetic energy of air molecules rises, allowing them to accommodate more water vapor, leading to higher humidity levels. Conversely, cooler air has a lower capacity for water vapor, which can result in condensation when it reaches its saturation point. Thus, as temperature fluctuates, so does the amount of humidity the air can contain.
The air that contains water vapor in equilibrium at a certain temperature is called saturated air. At saturation, the air has reached its maximum water vapor capacity at that temperature, leading to a balance between evaporation and condensation.
As elevation increases, temperature decreases approximately at the rate of 12.5 degrees c every 1km upwards. As air temperature decreases, its capacity to hold water is less. Therfore as elevation increases, its water capacity will decrease.
The atmosphere has a lower heat capacity.

It is lower then for Warmer air
The heating capacity of an air-to-air heat pump decreases as the outside air temperature drops. This is because the efficiency of heat transfer decreases as the temperature differential between the outside air and desired indoor temperature increases. As a result, the heat pump has to work harder to extract heat from the outside air, leading to a decrease in heating capacity.
its water holding capacity
The heat capacity of dry air is the amount of heat needed to raise the temperature of a given amount of air by 1 degree Celsius. Dry air has a lower heat capacity compared to water vapor, meaning it heats up and cools down more quickly. This affects temperature changes in the atmosphere by causing rapid temperature fluctuations, especially in dry regions where there is less water vapor to moderate temperature changes.
Higher temperature means greater energy content compared to a lower temperature. The energy required to change the temperature is proportional to the mass of the system, the specific heat capacity, and the temperature change.
The atmosphere has lower heat capacity
The amount of heat in air is measured using the specific heat capacity of air, which is about 1 kJ/kg°C. The total heat in air can be calculated by multiplying the specific heat capacity with the mass of air and the change in temperature.
The heat capacity of substances generally increases with temperature. This means that as the temperature of a substance rises, it requires more heat energy to increase its temperature by a certain amount. Different substances have different heat capacities, with some materials requiring more heat energy to raise their temperature compared to others.
Lowering air temperature will increase the relative humidity, assuming the amount of water vapor in the air remains constant. This is because colder air has a limited capacity to hold moisture, so the relative humidity will increase as the air temperature decreases.
