- 1. an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
Oct 24, 2023 · A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
Aug 12, 2024 · A barometer is defined as a meteorological instrument used to measure air pressure in the atmosphere. It forms a critical part of any weather station and is primarily used with other sensors to measure current and determine future weather conditions. It is also used in aviation to measure altitude.
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.
6 days ago · A barometer is a device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid.

Feb 27, 2024 · What Is a Barometer? A barometer is a scientific instrument designed to measure barometric pressure. Barometers as we know them date back to 1643 when the Italian inventor Evangelista Torricelli measured air pressure using a glass tube filled with mercury and open on its downward-pointing end.
Jul 3, 2022 · Instruments that measure air pressure are called barometers and people have been using them for weather forecasting and scientific research for hundreds of years. Let's take a closer look at how they work!
The meaning of BAROMETER is an instrument for determining the pressure of the atmosphere and hence for assisting in forecasting weather and for determining altitude. How to use barometer in a sentence.
Jan 5, 2018 · Barometer Definition. A barometer is a device that measures atmospheric pressure. The word "barometer" comes from the Greek words for "weight" and "measure." Changes in atmospheric pressure recorded by barometers are most often used in meteorology for forecasting weather.
The barometer is the instrument uses to measure the air pressure as it varies with the distance either above or below the sea level. It was invented by the Italian scientist E. Torricelli during the year 1643. He studied the characteristics of the mercury, by placing it in the vacuum.
Jul 3, 2019 · A barometer is a widely used weather instrument that measures atmospheric pressure (also known as air pressure or barometric pressure) -- the weight of the air in the atmosphere. It is one of the basic sensors included in weather stations.
