In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.

What weather instrument starts with ba?

Barometer is a weather instrument. It measures the atmospheric pressure.


What instrument is used to measure air pressure?

There are several options depending on the type of air pressure being measured:In the 1800's ships used a weather glass - a simple barometer - to measure changes in air pressure.To measure atmospheric (ambient air) pressure, a barometer is used. (It may be either an aneroid or a Mercury type of barometer.)For tires, it's a tire pressure gauge.In industrial processes and boilers the gauge is frequently called a manometer.For pressure vessels it is a Bourdon gauge.


What are two technologies that meterologists use to study the atmospheric conditions that produce weather?

using satellites,radar and other technologies,meterologists study the atmospheric conditions that produce weather. 2.many meterologists work as weather observes and measure factors such as wind speed, temperature, and rainfall. this weather information is then use weather maps,satellite images and computer models to patterns of weather forecasts.


What instrument measures cold fronts?

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. http://en.wikipedia.org/wiki/Barometer#Applications


What are the basic weather parameters and the instruments used?

The basic weather parameters and instruments used consist of a barometer to measure air pressure and a wind vane to measure the speed of the wind. Other instruments used include a thermometer and rain gauge.

What weather does millibars measure?

Millibars measure atmospheric pressure, which is an indicator of weather conditions. Low pressure systems usually bring cloudy, rainy, or stormy weather, while high pressure systems are associated with fair and clear skies.


What weather factor does a barometer measure in?

atmospheric pressure


Why was a barometer invented?

A barometer was invented to measure atmospheric pressure. This device is important for weather forecasting, as changes in atmospheric pressure can indicate upcoming weather conditions such as storms or fair weather.

What instruments are used to measure the atmospheric pressure?

Barometers, such as mercury and aneroid barometers, are commonly used to measure atmospheric pressure. Other instruments like electronic pressure sensors and weather balloons equipped with instruments can also measure atmospheric pressure.


What is A device that measures atmospheric pressure is called?

A device that measures atmospheric pressure is called a barometer. It is commonly used in weather forecasting to track changes in air pressure, which can indicate changing weather patterns.


What is a barrometer?

A barometer is a scientific instrument used to measure atmospheric pressure. It helps in determining weather patterns as changes in atmospheric pressure can indicate approaching weather systems. There are two main types of barometers: mercury barometers and aneroid barometers.


What is milibar?

The milibar is a unit of pressure used in meteorology and is equal to one thousandth of a bar, which is roughly equal to atmospheric pressure at sea level. It is commonly used to measure air pressure in weather reports and forecasts.


What weather tools are used in a desert?

Weather tools commonly used in deserts include anemometers to measure wind speed, barometers to measure atmospheric pressure, and hygrometers to measure humidity. Additionally, thermometers are used to measure air temperature, and weather satellites are used for monitoring large-scale weather patterns in desert regions.


What is an weather instrument that starts with b?

The most common is the barometer, which measures atmospheric air pressure.


What can a barometers be used for?

A barometer measures barometric pressure, that is, atmospheric pressure. Because air flows from high pressure areas to low pressure areas, rising or falling barometric pressure tells us that we should expect a change in the weather. For example, a storm is often preceded by a drop in barometric pressure. A barometer is an indispensable tool for a meteorologist, a captain of a ship, or anyone else who needs to predict the weather.


What is function of a barometer?

To measure atmospheric pressure. In general, higher atmospheric pressures (also called "higher barometric pressure") is generally associated with good weather, while low or falling pressure is generally linked to rain or bad weather.
