Absolute Humidity: The actual amount of water vapor present in the air, usually measured in grams per cubic meter.
Relative Humidity: The ratio of the amount of water vapor present in the air to the maximum amount the air could hold at a specific temperature, expressed as a percentage.
Specific Humidity: The ratio of the mass of water vapor to the total mass of moist air parcel.
Measuring Humidity
Humidity is measured using instruments called hygrometers. These devices can measure relative humidity as well as absolute humidity.
Humidity can have various effects on the environment and living organisms. High humidity can make it feel hotter than it actually is, while low humidity can lead to dry skin and respiratory issues. In addition, humidity plays a crucial role in the formation of clouds and precipitation.
