What is a barrometer?
An apparatus used to measure atmospheric pressure and its weather related changes.
What is measured by millibars?
atmospheric pressure in measured in millibars
How the barometer is used?
A barometer is advice used to atmospheric pressure. They are commonly contain water, air, or mercury. The medium used raises and falls in a tube with a reservoir at the base. The pressure from the outside air pushes on the medium in the exposed reservoir. This push is what causes the medium raise or fall. The measure of the barometer can indicate local weather patterns. High pressure indicates fair weather, while low pressure indicates a storm.
What is the name for pressure caused by the weight of the atmosphere?
Simply put, atmospheric pressure is the force exerted on a measuring point by the weight of the air molecules on top of that point. Standard atmospheric pressure, measured at sea level at 59F or 15C, is used as a reference point and is equal to 29.92 inches of mercury or 1013 millibars of pressure.
What is the physical quantity measured by a barometer?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.See the related link .A barometer measures air pressure.A barometer is an instrument that is used to measure atmospheric pressure.
What two units of air pressure are used weather reports?
The two most common units used for air pressure in weather reports are: Inches of Mercury and Millibars.

What two units of air pressure are used the most in weather reports?
1,2,3,4,5,6,7,8,9, that are the units ( i think) well bye!

There's a same question here you can check it What_two_units_of_air_pressure_are_used_in_weather_reportsBut though I didnt understand too
How are negative numbers used in weather reports?
They are used for very cold temperatures.
What did people use the barometer for?
To measure pressure in the air. Meteorologists use them (weather people) a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
What is the baromter used for?
For measuring atmospheric pressure which is used in weather forecasting.
Barometer are used to predict weather because weather is related to changing what?
The weather changes in relation to the air pressure. Air molecules always travel towards low pressure where there is less force acting on them. This has an effect on the weather. Generally, high pressure means good weather and low pressure means bad weather. Barometers measure the pressure, often in Hectopascals.
What kinds of data are used to make weather maps?
Data used to create weather maps come from different sources. Weather balloons, satellites, ship and airplane reports, and wind profiler data are also used.
What is a barometers?
A barometer is a device used to measure atmospheric pressure. If pressure is high (good weather), then pressure on the barometer will exceed 1000 millibars. If the pressure is low (bad weather), then the pressure reading on the barometer will be below 1000 millibars.
