WebSep 9, 2024 · How does a liquid barometer work? A water barometer or storm glass is used to predict stormy weather. It works because of changes in atmospheric pressure. … The top of the spout is above the water level and open. When air pressure sinks lower than when the body was sealed with water the water level in the spout rises above the level in the body. The concept that decreasing atmospheric pressure predicts stormy weather, postulated by Lucien Vidi, provides the theoretical basis for a weather prediction device called a "weather glass" or a "Goethe barometer" (named for Johann Wolfgang von Goethe, the renowned German writer and polymath who developed a simple but effective weather ball barometer using the principles developed by
