When the barometric pressure is 29.49 inches of Mercury it means the pressure is slightly less than that at sea level. Sea level atmospheric pressure is regarded as 1 atmosphere (= 760 mmHg = 29.92 in Hg = 14.7 lb/in2 = 101.3 KPa)
Pressure lowers (the inches of mercury falls) as one's elevation above sea level increases or as low pressure fronts associated with warmer or wetter weather systems move into an area.
The indicated 1/2 inch difference would inicate being on a slight height of land, or that there was a low pressure zone (damp weather perhaps) in the area. More significant for weather is the rate of change of the barometric pressure.
29 mm Hg, or mercury, as it would read in a mercury manometer.
It is a pressure reading. The mercury is put in a tube and inverted and it pulls a vacuum. As the atmospheric pressure changes, the distance changes. Low pressure means bad weather, high pressure means good weather. We usually use digital or mechanical instrumentation these days, but with the same units of measure (mm Hg).
It's the height in inches of a column of Mercury pushed to that height by the atmosperic pressure of air at the location. The instrument used is called a Barometer. The height varies due to location on the planet's surface, the weather and height the instrument is above sea level.

Does the barometric pressure seldom change?
Barometric pressure typically changes frequently due to weather patterns, such as high and low-pressure systems moving through an area. These fluctuations can impact the weather conditions experienced in a specific location.
What does up when the rain comes down?
If you mean what 'goes' up when the rain comes down, then the answer is the barometric pressure. A low pressure cell, which is a chief indicator of a rain storm, occurs when the barometric pressure drops below 30 points. As the storm dissipates, the low pressure cell changes, causing the barometric pressure to rise.
What does weather inches in pressure mean?
Weather inches in pressure refers to the measurement of air pressure using inches of mercury (inHg). This is a common unit of measurement used in meteorology to indicate atmospheric pressure, where a normal sea-level pressure is around 29.92 inHg. Changes in atmospheric pressure can influence weather patterns, with high pressure typically associated with fair weather and low pressure often bringing storms.
Does flies biting mean rain is coming?
No, flies biting does not necessarily indicate that rain is coming. Fly behavior is not a reliable indicator of weather patterns. Changes in barometric pressure and other environmental factors are more closely linked to predicting rain.
What does 29.91 in and falling mean on the barometer?
A barometer reading of 29.91 inches and falling indicates that the atmospheric pressure is decreasing. This usually signifies an approaching low-pressure system and potentially stormy weather conditions.
What does Barometric reading falling mean?
Falling barometric pressure usually indicates wet weather is on the way.
Does the barometric pressure seldom change?
Barometric pressure typically changes frequently due to weather patterns, such as high and low-pressure systems moving through an area. These fluctuations can impact the weather conditions experienced in a specific location.

Trouble code P0108 means: Manifold absolute pressure or barometric pressure circuit high input
What does code P0106 mean?
Trouble code P0106 means: Manifold absolute pressure or barometric pressure circuit, range or performance problem
What does code p0108 mean on 2002 ptcruiser?
Trouble code P0108 means: Manifold absolute pressure or barometric pressure circuit high input
If barometric pressure falls in one part of the world must it rise somewhere else?
Not necessarily. Barometric pressure changes are influenced by weather systems and atmospheric conditions in a specific region. So, a drop in pressure in one area does not always mean an increase in pressure elsewhere, as it depends on the movement and interaction of different air masses.
What does code P0107 mean in a 98 Oldsmobile intrigue?
Trouble code P0107 means: Manifold absolute pressure or barometric pressure circuit low input
What does code P0106 on a 2000 Mazda protégé mean?
Trouble code P0106 means: Manifold absolute pressure or barometric pressure circuit, range or performance problem
What does meterological data mean?
Meteorological data is information obtained from the atmosphere, Such as; barometric pressure, humidity, wind speed, and air temperature.
What does steady air pressure mean?
Steady air pressure refers to a consistent level of atmospheric pressure that remains relatively unchanged over a period of time. It indicates stable weather conditions with little to no fluctuations in barometric pressure.
