The traditional mercury barometer measures air pressure using a column of mercury inside a glass tube. It works by measuring the weight of air particles against a metal spring. A decrease in air pressure means that a storm is on the way, while an increase suggests good weather will come soon after.Ī meteorologist can use an aneroid barometer or a digital one to measure atmospheric pressure. BarometerĪ barometer measures atmospheric pressure. Meteorologists must take this tradeoff between accuracy and speed into account when choosing the size of anemometer they will use for a particular project.Īnemometers are typically placed on top of tall towers in order to get accurate readings, but if not present meteorologists may instead place them atop mountains or other high points around their area in order to achieve similar results. Different cup sizes can be used depending on the desired accuracy–the larger the size, the less sensitive it will be because there will be fewer cups spinning at any given time conversely, smaller sized cups would provide higher levels of accuracy but only if they were able to spin faster due to their reduced size. The anemometer is common among meteorologists who are hoping to predict weather patterns based on the velocity and direction of winds.Īnemometers typically have three or four “cup”-like cups that spin around in order to measure speed, which is then further connected via thin metal wires into an electric current for processing purposes. It works by measuring the deflection of wind against a known object. The anemometer is a device used to measure wind speed. Wind vanes are used when there isn’t yet any data available for other methods like electronic sensors or satellite images. In other words, when there’s a strong breeze outside your house you can be sure that no matter what angle you put this gadget into – it will tell you exactly how much power there is behind all those antsy breezes. There are two types of wind vanes: floating-vane type with blades fixed at their ends which always show the direction from where the wind blows and feathering-type that has freely moving blades, each blade rotating about its endpoint as it assumes different angles towards the direction of movement. ![]()
