Very simply put, cold air is denser than warm air - thus as air of differing temperature passes over you (or rather your barometer) the barometric pressure will change.
The arrival of warm air will cause the barometric pressure to fall and as warm air holds more moisture than cold air a falling barometric pressure will herald the arrival of rain.
Conversely, if the pressure rises this will indicate some nice sunny days to come
Further, if the pressure falls (or rises) fast, then there are likely to be strong winds.

How does digital barometer work?
I bought a digital weather station recently so I've been studying the various features one of which is a digital barometer. This particular one lets you set the altitude of your house for greater acuracy. A barometer's range as I understand it is from 28 to 32 inches. When the barometer falls it is indicating a change in the weather such as rain or a storm. The lower the number goes the more severe the storm. When it rises it indicates that better weather is coming. Remember, though, a barometer tells you what the weather will be not what the weather is. My instrument seems to predict what the weather will be in about 12 hours with a fair amount of acuracy. By the way the unit I bought was a relatively inexpensive one from Radio Shack and it seems to be fine
How global weather is monitored?
Global weather is monitored through a network of satellites, radars, weather stations, and weather balloons. These tools provide real-time data on temperature, precipitation, wind patterns, and other meteorological factors. Meteorologists use this data to create weather forecasts and monitor climate patterns on a global scale.
How does a weather man tell the temperature?
A weatherman can tell the temperature by using a thermometer that measures the air temperature at a specific location. They may also use data from weather stations or satellites to get temperature readings from different regions.
Is using past weather data an accurate way to predict the weather?
Using past weather data can provide some insights into general patterns and trends, but it may not always accurately predict future weather conditions. Weather forecasting relies on a combination of historical data, current atmospheric conditions, and advanced modeling techniques to make predictions. While past data can be a useful tool, it's just one piece of the puzzle when it comes to predicting the weather.
Air pressure is measured by what?
Air pressure is typically measured using a barometer. This instrument can be either an aneroid barometer or a mercury barometer. It provides a numerical value that represents the force exerted by air molecules in a specific area.
What is an example of a sentence using the word barometer?
The barometer measures atmospheric pressure.
The advantage and disadvantage of a barometer?
Advantage: A barometer can accurately measure changes in atmospheric pressure, which helps predict changes in the weather. Disadvantage: Barometers require calibration and maintenance to ensure accuracy, and they can be sensitive to factors like temperature and altitude.
Can you make a sentence using the word predict?
I predict that I will die, eventually.
What is a sentence using predict?
I predict that the weather is going to be sunny all week.
How would you check the weather in Antarctica?
You can measure weather using a thermometer, a barometer and an anemometer or other tool of choice.
What are the Advantages and disadvantages of using a barometer?
Advantages: Barometers provide real-time measurements of atmospheric pressure, which can help predict weather changes. They are relatively simple instruments to use and can be portable for outdoor activities or professional meteorological use. Disadvantages: Barometers require calibration and maintenance to ensure accuracy. They may not provide detailed information on other weather parameters like temperature or humidity.
How do scientists gather weather data from high in the atmosphere?
scientists gather weather data from high in the sky using weather satellites
How to Predict the Weather Using a Barometer?
Of all weather instruments essential to forecasting, the barometer tops the list. Why? Because every weather change is preceded by a rise or fall in air pressure, and air pressure is just what the barometer measures. If you compare two barometer readings taken an hour or two apart, you will know immediately if the air pressure is rising, falling, or staying the same. And as a result you will be able, with a fair amount of accuracy, to predict tomorrow’s weather. RISING BAROMETER: When the air pressure measures higher than it did in your previous reading, the air is becoming denser, and the barometer is said to be rising. This tells you that clearer, drier, cooler weather is on the way. If the barometer is rising very rapidly from a low position, the weather will clear up very soon, and it will probably become quite windy. But if the barometer rises from a low position gradually and steadily, a long period of good weather is just around the corner. If the barometer is already high and suddenly starts to rise rapidly, expect a sudden drop to follow shortly, and with it, bad weather to come. FALLING BAROMETER: A falling barometer usually indicates rain, wind, and warmer weather. Take note of the speed at which the barometer falls. A very large and rapid drop in air pressure is a sure sign of an approaching storm. If the barometer falls suddenly, but not too far, expect wind and brief showers. If the barometer falls slowly and steadily to a moderately-low position, it may rain nearby, but not necessarily in your immediate area. UNCHANGING BAROMETRIC PRESSURE is a pretty good indication that whatever weather you’re currently enjoying is not about to change any time soon. IMPRESS YOUR FRIENDS AND NEIGHBORS! With a little experience in charting barometric pressure in your area, you will soon become skilled at noting any changes which are out of the ordinary. At this point, your weather-predicting abilities may begin to rival those of your local TV weatherman. And that would be something to brag about!

What is the basic instruments for measuring atmospheric pressure?
Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
What instruments do scientists use to predict tornadoes?
For long-term outlooks, scientists use computer models to predict the behavior of weather systems. This can predict the general risk for tornadoes across a region, but not wehat specific areas will likely be hit. On the short term, the rotation in a storm that may produce a tornado is detected using Doppler radar. The radar may also detect the tornado itself.
