It isn't constant anywhere, no. 1013.25 mb is simply the average pressure, which is particularly important at sea level because that is how observations are standardized. But atmospheric pressure always varies no matter where you are, as a consequence of having weather.

Is it true that the atmospheric pressure remains a constant 1013 MB at sea level?

While 1013 hPa (millibars) is commonly used as the standard atmospheric pressure at sea level, actual pressure can vary due to weather conditions, temperature, and altitude. Atmospheric pressure typically ranges from about 980 to 1050 hPa in different weather situations. Therefore, while 1013 hPa serves as a reference point, it is not a constant value.

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 normal barometric pressure in Phoenix?

The normal barometric pressure in Phoenix, Arizona is around 29.92 inches of mercury (inHg) or 1013 millibars (mb). This is considered standard atmospheric pressure at sea level.


What is the pressure of the equator?

The average atmospheric pressure at the equator is around 1013 millibars or 14.7 pounds per square inch. This pressure can vary slightly due to changes in weather patterns and altitude above sea level.


What is a typical value for the atmospheric pressure for pietermaritzburg?

The typical atmospheric pressure in Pietermaritzburg, South Africa, is around 1013 hPa (hectopascals) or 1,013 millibars, which is close to the average sea-level pressure. However, it can vary slightly depending on weather conditions and altitude, as the city is situated at about 750 meters above sea level. Generally, atmospheric pressure can range from about 980 hPa during low-pressure systems to around 1,050 hPa during high-pressure systems.
