What does a falling barometric reading (atmospheric pressure) indicate?

∙ 7y agoGenerally a falling barometer means poor weather or precipitation is coming and a rising barometer means it will soon clear up. A reading of >30 generally corresponds to fair weather while <30 means clouds/rain/etc. may be coming. In my experience, a barometer can sometimes predict weather quite well but this is really just a guideline and just like the weather man, it is sometimes wrong. It is best to watch how one acts before, during, and after storms and to see the difference between clear and cloudy days to get an idea of what the readings mean.
Falling barometric pressure usually indicates a depression - which normally brings rain.

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.
Will it rain when barometric pressure drops?
Actually it's the other way around because decreasing barometric pressure initiates the upward flow of air that is essential for cloud development and then rain. Hope this helps! :) Actually no, because decreasing barometric pressure at the surface is a result of rising air and it also causes convergence of air at the surface. Sometimes in thunderstorms when the downdraft (ie rain and hail) is intense, it can actually cause a rise in barometric pressure at the surface since the air has a strong sinking motion hence the name downdraft. Thanks to the above user for attempting to give a correct and complete answer, but this answer from me is more correct and complete.
What kind of weather is coming if the air pressure is falling?
Falling air pressure is usually an indication that a storm is coming.
What is the significance of the barometer?
The barometer measures air pressure. Its main usefulness is when the pressure is rising or falling. If you are in a house with a basement and the sky looks ominous and you suddenly see the gauge on the barometer decreasing, it means that the air pressure around your house has started falling fast. It also means you should get into your basement as fast as possible so you will avoid the tornado that will blow your house away. A falling barometer indicates stormy weather is coming. A rising barometer indicates fair weather is coming. With satellites and weather reports we have less need for barometers except during severe storms when we most need such reports.
What is falling air pressure?
Snow storms. It is most noticeable in/at the center of a Low Pressure System.
What does Barometric reading falling mean?
Falling barometric pressure usually indicates wet weather is on the way.
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.
What does falling atmospheric pressure forewarn?
Iy forewarns because the lower the pressure the taller a cloud can be. So cumulonibuses need low pressure to produce tornadoes and that is why falling pressure can indicate a tornado. I stress the word can.
What is the barometric pressure in Rio?
Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the "weight of the air". A barometer measures barometric pressure. Measurement of barometric pressure can be expressed in millibars(mb) or in inches or millimeters of mercury (Hg). Normal pressure at sea level is 1013.3 millibars or 29.92 inches of mercury. Fluctuations in barometric pressure are usually a sign of weather conditions. A rise in pressure usually means improving weather while falling pressure may reflect impending inclement weather. Barometric pressures will also vary with altitude and moisture.Barometric pressure in rio is 29.78 in hg and still rising
What is baromatic pressure?
Hi Falling barometric pressure means the atmosphere at the barometer is becoming less heavy. It also generally means a storm of some sort is coming with inclement weather. Here's a link to use for using a barometer and clouds to forecast the weather: http://web2.iadfw.net/danb1/clouds.htm

Explain why barometric pressure usually falls with the approach of a cold front or occluded front?
falling down

Does barometric pressure affect fishing?
When the barometric pressure is high (usally above 30.15) the fishing is usually bad. When you have a falling pressure the fish are usually more aggresive at this time and this would be a favourable time to fish. Also when you have a steady pressure anywhere from 29.90-30.10 this is a good time to fish as well. This being said when the pressure is rising or holding steady above 30.15 you might as well hang it up and stay home with the wife. If the pressure is falling and the bad weather hasn't reached you yet, then as a good friend of mine Brad Paisley said once " I'm gonna miss her." Tight Lines and rip some LiPS!

What does a falling barometric reading?
Any reading above 1012 milibars.
What happens to the pressure inside of a balloon as it floats higher and higher?
The atmospheric pressure go on falling. So the pressure in the balloon. It takes lot of height to get the pressure reduced. I mean, the reduction in the pressure can not be easily measured for short height.
