Kosteusmäärä, or humidity, refers to the amount of water vapor present in the air. It is a crucial factor in meteorology and environmental science, influencing weather patterns, human comfort, and various biological processes. Humidity is typically expressed as a percentage, representing the ratio of the current absolute humidity to the highest possible absolute humidity at a given temperature.

There are two main types of humidity measurements: absolute humidity and relative humidity. Absolute humidity indicates the actual amount of water vapor in the air, usually measured in grams per cubic meter. Relative humidity, on the other hand, compares the current absolute humidity to the maximum amount of water vapor the air can hold at a specific temperature. This is expressed as a percentage and is more commonly used in weather reports and daily life.

High humidity levels can lead to discomfort and health issues, such as heat exhaustion and heatstroke, as the body struggles to cool itself. Conversely, low humidity can cause dry skin, respiratory problems, and increased static electricity. Understanding and monitoring humidity levels is essential for various applications, including agriculture, indoor air quality, and weather forecasting.
