ilmapaineen
Ilmapaineen, in Finnish meteorology, refers to atmospheric pressure—the force per unit area exerted by the weight of the Earth's atmosphere on surfaces at a given location. It results from gravity acting on the air column above and varies with altitude, temperature, and weather systems.
At sea level, the standard atmospheric pressure is about 1013.25 hPa (hectopascals), equivalent to 101,325 Pa.
Pressure is measured with barometers, including mercurial, aneroid, and digital devices. Modern practice often uses digital
Weather and climate are strongly influenced by ilmapaineen variations. High-pressure systems (anticyclones) are generally associated with
Historically, measurements of atmospheric pressure began with early barometers developed in the 17th century, with standardization
