Weather terms - Humidity

Humidity itself simply refers to the amount of water vapour in the air. However, the amount of water vapour that the air can contain varies with air temperature and pressure. Relative humidity takes into account these factors and offers a humidity reading which reflects the amount of water vapour in the air as a percentage of the amount the air is capable of holding. Relative humidity, therefore, is not actually a measure of the amount of water vapour in the air, but a ratio of the air's water vapour content to its capacity. When we use the term humidity on the screen, we mean relative humidity.
