What determines humidity in the air?

Explanation:
Humidity is a measure of how much water vapor is in the air. The amount of water vapor present determines humidity: more vapor means higher humidity. Temperature matters because warm air can hold more water vapor, so relative humidity is influenced by both the vapor amount and the air’s temperature. Wind speed and atmospheric pressure don’t set humidity themselves; they can influence moisture movement or condensation, but they don’t determine the actual water-vapor content in the air.
