Herein, is there a barometer in my phone?

Says John Celenza, the lead meteorologicaldeveloper at Weather Underground, "the barometer is probablyused on the phone to aid in correcting altitude measurementsby the GPS." The atmospheric pressure is directlyrelated to elevation, so a barometer can very easily be usedas an altimeter, measuring your altitude.

One may also ask, what does pressure mean with weather? It is well established that high pressureis generally associated with nice weather, while lowpressure is generally associated with cloudy, rainy, orsnowy weather. The motion of air in the atmosphere above ourheads plays a large part in the weather we experience hereat earth's surface.

Also question is, what's the use of barometer?

Barometer, device used to measureatmospheric pressure. Because atmospheric pressure changes withdistance above or below sea level, a barometer can also beused to measure altitude. There are two main types ofbarometers: mercury and aneroid.

Why do iPhones have a barometer?

Barometer has the role to measure air pressure.This reading is important because it helps youriPhone determine altitude, as well as relative elevationchanges. More, it transforms your iPhone in an actualbarometer, because air pressure reading is used forweather forecasting!

How do you measure air?

An instrument that measures air pressure iscalled a barometer. One of the first barometers was developed inthe 1600s. The original instrument had mercury in the small basin,with an upside down glass tube placed in the mercury. As airpressure increased, the pressure would force more mercury in thetube.

How does a barometer work simple?

The barometer works by balancing the weight ofmercury in the glass tube against the atmospheric pressure, muchlike a set of scales. With an increased weight of air above thereservoir, the mercury level rises to a higher level.

How does a stick barometer work?

Photo: A Torricellian barometer (sometimes calleda mercury barometer) is an inverted (upside-down) glass tubestanding in a bath of mercury. Air pressure pushes down on thesurface of the mercury, making some rise up the tube. The greaterthe air pressure, the higher the mercury rises.
