Question

When would the relative humidity of an air mass increase?

Answer 1

Answer: When the air mass moved from a warm desert over a cold ocean.

Explanation:

Relative humidity refers to the air´s water-vapor content relative to the temperature. Warm air is likely to have higher moisture, as it holds more water vapor than cold air. Therefore, the air has a higher relative humidity when the air gets cool, and lower relative humidity when is warmer.

Atmospheric cooling happens in different ways, including the movement of an air mass to a cooler area.
