Barometrinen

Barometrinen is a Finnish adjective meaning barometric. It describes phenomena, measurements, or instruments related to the barometer and to atmospheric pressure. The closest English equivalents are barometric or barometrical, and the term is commonly used in Finnish scientific and technical language to refer to pressure-related concepts.

The word derives from the barometer, an instrument designed to measure atmospheric pressure. The barometer itself takes its name from Greek baros, meaning weight, and metron, meaning measure. In Finnish, barometrinen is formed with the same root and the typical adjectival suffix -inen, signaling a relation to the barometer or to pressure.

In practical usage, barometric pressure is the atmospheric pressure at a given location and time. It is a central variable in meteorology, where measurements are used to forecast weather, track storms, and understand climate patterns. Barometric readings are typically expressed in hectopascals (hPa) or millibars, with standard sea-level pressure about 1013.25 hPa. Weather maps often show isobars, lines connecting points of equal barometric pressure, to illustrate pressure systems.

Barometric concepts also appear in aviation and science. Barometric altitude relies on changes in atmospheric pressure to estimate elevation, and modern aircraft use electronic sensors and altimeters based on barometric measurements. In physiology and environmental science, variations in barometric pressure can influence experiments and some biological processes, though the effects are usually secondary to other environmental factors.
