Definition: Humidity refers to the amount of water vapor present in the air. It is an important factor in weather and climate, as it influences temperature, precipitation, and comfort levels for living organisms.
1. Absolute Humidity: Absolute humidity is the actual amount of water vapor present in a unit volume of air, usually expressed in grams per cubic meter (g/m3).
2. Relative Humidity: Relative humidity is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor the air can hold at a specific temperature. It is expressed as a percentage.
Several factors can affect humidity levels:
Humidity can be measured using instruments called hygrometers. There are different types of hygrometers, including psychrometers, hair hygrometers, and electronic hygrometers, each with its own method of measuring humidity.
Humidity can have various effects, including:
