It depends on what you mean by change. If your mean "Does the pressure swing from lows like 28 inches Mercury (severe low) to 32 inches mercury (severe high)?" then the answer would be yes. This sort of shift is what causes most severe weather disturbances, such as lines of thunderheads. The collision of a high pressure and low pressure area cause strong winds, usually some precipitation, and even tornados and other severe weather.
If, however, you mean "Is the barometric pressure constant most of the time?" then the answer would be no. The barometric pressure has constant small fluctuations, based on a number of factors.

What causes barometric pressure?
Barometric pressure is caused by the weight of the air pushing down on the Earth's surface. It is influenced by factors such as temperature, altitude, and weather patterns. Changes in barometric pressure can indicate changes in weather conditions.
How does humidity impact barometric pressure?
Humidity can impact barometric pressure by affecting the density of the air. When humidity levels are high, the air becomes less dense, causing a decrease in barometric pressure. Conversely, low humidity levels can lead to denser air and an increase in barometric pressure.
What is barometric trend?
The change in barometric pressure, air pressure, in the last three hours, measured in milibars. See the following link for the symbols that show past change: http://www.hpc.ncep.noaa.gov/images/pressure_trendNEW.gif
Is barometric pressure the same as atmosheric pressure?
Barometric pressure refers specifically to the pressure exerted by the atmosphere, while atmospheric pressure is the force per unit area exerted against a surface by the weight of the air above that surface. In essence, barometric pressure is a type of atmospheric pressure.
What causes increases in barometric pressures?
Increases in barometric pressure are usually caused by the sinking of air masses or high-pressure systems in the atmosphere. These high-pressure systems bring more air molecules closer to the Earth's surface, resulting in an increase in pressure. Additionally, changes in wind patterns and weather systems can also lead to temporary increases in barometric pressure.
How does the atmosphere change the earth?
Barometric pressure,humidity,and temperature.
How does barometric pressure change with altitude?
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
How can dogs tell when a storm is approaching?
They can detect the change in barometric pressure that precedes a storm.
How are blood pressure and barometric pressure associated?
Changes in barometric pressure can affect blood pressure, especially in individuals who have cardiovascular conditions. When barometric pressure drops, it can cause blood vessels to dilate, leading to lower blood pressure. Conversely, when barometric pressure rises, it can cause blood vessels to constrict, resulting in higher blood pressure.
Is barometric pressure the same as air pressure?
Yes, barometric pressure is a specific type of air pressure that is measured using a barometer.
What causes barometric pressure?
Barometric pressure is caused by the weight of the air pushing down on the Earth's surface. It is influenced by factors such as temperature, altitude, and weather patterns. Changes in barometric pressure can indicate changes in weather conditions.
What is the barometric pressure in Chesapeake Va now?
I do not have real-time data on barometric pressure. You can check the current barometric pressure in Chesapeake, VA by using a reliable weather website or app.
How is barometric pressure abbreviated?
Barometric pressure is often abbreviated as "BP" in meteorology and scientific contexts.
What does sudden decreases in barometric pressure indicate?
A sudden decrease in barometric pressure is a sign that a storm is coming.
What is the average barometric pressure change in Tucson Arizona during monsoon season?
During monsoon season in Tucson, Arizona, the average barometric pressure change is typically around 0.05-0.10 inches of mercury. This change is often associated with the incoming moisture and atmospheric instability that characterizes the monsoon season in the region.
How does humidity impact barometric pressure?
Humidity can impact barometric pressure by affecting the density of the air. When humidity levels are high, the air becomes less dense, causing a decrease in barometric pressure. Conversely, low humidity levels can lead to denser air and an increase in barometric pressure.
What are examples of standard ground observations for a simple weather forecast?
temperature, change in barometric pressure, humidity
