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.

What is normal atmosphere measured in?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
What range does sea level pressure values generally fall in?
980 mb to 1045 mb (Those are the values for deep low-pressure systems and strong high-pressure systems). The average sea-level pressure is 1013 mb. The highest and lowest sea level pressures record are 1084 mb and 870 mb.
Is 1034 millibars high pressure?
Yes, 1034 millibars in barometric pressure is high. Normal pressure is 1013 millibars.
Which layer in the atmosphere has the most air pressure?
The troposphere. The lower you go, the higher the air pressure. The average air pressure at sea level is 1013 mbar, or 101.3 kPa.
What do high and low pressure systems have to do with wind?
A high pressure system has a weaker horizontal pressure gradient than a low pressure system, which means the atmospheric pressure varies widely in a low pressure system and doesn't vary much in a high pressure system. The wind speed depends on the strength of the horizontal pressure gradient.On a meteorological map, the horizontal pressure gradient is marked with isobars, which are lines with match the points with the same atmospheric pressure. A high pressure system is characterized by widely spaced isobars while low pressure systems are noted by tightened close isobars.A high pressure system may have an air pressure of 1028 hPa in his core and 1013 hPa in its periphery: the air pressure varies about 16 hPa. A low pressure system may have an air pressure of 987 hPa in its core and 1013 in its periphery : the air pressure varies about 26 hPa. So, the winds will be very light and even non-existent in a high pressure system while the winds will be very strong and even turbulent in a low pressure system.
What is normal atmosphere measured in?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
What is the normal atmospheric pressure in MB?
1013 mb
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 boiling point of sea water?
At atmospheric pressure (1013 mbar) is 100.65 °C
Who knew that there is air pressure?
Pascal defined atmospheric pressure as an atmosphere over a meter being 1013 millibars at sea level and 20 deg C Newton stated it to be a Kg over a meter being 1.013 Kpa
How much pressure is exerted by air at sea level?
1013 mb
What is pressure at sea level?
1013 millibar or 762 mm of Mercury
Standard sea level pressure (1 ATM) in millibars is?
Standard air pressure at sea level is 760 millibars.
What is the air pressure inside a hurricane?
Air pressure inside a hurricane is low typically less than 995 millibars (normal sea level pressure is 1013 millibars). Stronger hurricanes generally have a lower central pressure.
What range does sea level pressure values generally fall in?
980 mb to 1045 mb (Those are the values for deep low-pressure systems and strong high-pressure systems). The average sea-level pressure is 1013 mb. The highest and lowest sea level pressures record are 1084 mb and 870 mb.
What is 760 mm atmospheric pressure?
760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.
What Gas pressure values at sea level and 0 degrees celsius?
If you were at sea level, the weight of the air pressing down on you would be 1.03 kilograms per square centimeter.or 1013.25 millibars.
