Barometric pressure decreases as a hurricane gets stronger. A Category 1 storm will have barometric pressure of at least 28.94. At the other end of the scale, a Category 5 storm will have air pressure of 27.17 or lower. Meteorologists also use a measurement called a millibar, which is faster for them to calculate, but gives measurements equivalent to barometer readings. These measure the intensity of a storm. Hurricane Wilma, a Category 5 storm which came near the end of the particularly active and destructive 2005 season, holds the current record (as of mid-2014) for intensity. When the storm was strongest, its low barometric pressure was 26.82, or 882 millibars. By contrast, there is a tie for 10th place on the list of most intense Atlantic hurricanes. The Cuba storm of 1924 and Hurricane Ivan (2004) each had a low barometric pressure of 26.88, or 910 millibars.

How can you use a barometer to detect changes in air pressure?
A barometer is used in 2 ways. First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming. Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.
When the barometer falls can we expect good weather or bad weather?
Falling barometer means low pressure, which means a storm/ bad weather.
What Weather instrument indicates a storm is coming?
In order to know that a storm is coming, you need to know the air pressure. Storms are normally associated with a Low Pressure System. A Barometer can be a tool you can use to predict an oncoming storm.
When the barometer is dropping what is the air pressure doing?
increasing
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.

Do mercury barometer fal or rise when a storm is approaching?
it falls , due to low pressure ...
How does a barometer instrumental in predicting storms?
It can detect air pressure, which will change when nearing a storm.
When the barometer falls can we expect good weather or bad weather?
Falling barometer means low pressure, which means a storm/ bad weather.
How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
Can track storms at different altitudes?
They use radar to watch the storm move and a barometer to study its pressure!

Does air pressure change with weather?
Yes, that is why a barometer is used to predict the weather - low pressure increases the likelihood of a storm, whereas high pressure means that it should stay dry
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
How the barometer is used?
A barometer is advice used to atmospheric pressure. They are commonly contain water, air, or mercury. The medium used raises and falls in a tube with a reservoir at the base. The pressure from the outside air pushes on the medium in the exposed reservoir. This push is what causes the medium raise or fall. The measure of the barometer can indicate local weather patterns. High pressure indicates fair weather, while low pressure indicates a storm.
