Barometer barometric pressure.

The barometer officially came into existence in 1643, invented by the Italian physicist Evangelista Torricelli. The background of barometers is as a scientific instrument to measure the weight of air pressing down upon it. Atmospheric pressure (which is to say the weight of the air directly above us) acts as an indicator of weather.
