Ambient Weather WS-YG720 Thermometer, Liquid Barometer, Hygrometer and Clock Weather Station This traditional weather station is both a work of art and an instrument at home in any fine study, library, office or upscale restaurant The rich, wood framed classic weather station measures temperature, barometric pressure (liquid), humidity (-percent) with analog clock The concept that 'decreasing atmospheric pressure predicts stormy weather' was postulated by Lucien Vidie-and it's the basis for a weather prediction device called a storm glass or liquid barometer A narrow spout connects to the body below the water level and rises above the water level, where it is open to the atmosphere When the air pressure is lower than it was at the time the body was sealed, the water level in the spout will rise above the water level
