Weather: Is the Pressure Getting to You?
Is the Pressure Getting to You?
The seventeenth century was quite an age of discovery. Evangelista Torricelli, a student of Galileo, invented the first mercurial barometer. It consisted of a glass tube open at one end and closed at the other. The open end was covered and immersed into an opened container of mercury. The cover was removed, and the mercury moved up the tube, about 30 inches above the container. That height represents atmospheric pressure. The weight of the atmosphere on the surface of the mercury exerts a pressure transmitted through the fluid, forcing it to rise. The greater the weight, the higher the rise. The barometric pressure seldom goes above 31 inches or drops below 29 inches. Normal sea-level pressure is 29.92 inches.
The type of barometer that you are probably most familiar with, the kind you see in stores and give as presents, is the aneroid barometer. As a rule, falling pressure means deteriorating weather, and rising pressure means fair or improving weather.
But the "inch" is really not a unit of pressure, or force per area. It is a unit of length. So a metric unit has been defined to describe normal atmospheric pressure, called a "bar," and the instrument becomes a "barometer." Actually, normal average sea-level pressure is 1.01325 bars, or 1,013.25 millibars (mb). The millibar is a commonly used unit of pressure.
During the same Galileo-Toricelli era, French scientist and philosopher Blaise Pascal discovered that air pressure decreases with height, and pressure changes at ground level at any one place can be related to daily weather changes. In his honor, the newest unit of pressure has become the hectopascal (Hpa). The pascal (Pa) is one hundredth of a millibar. The hectopascal is one hundred pascals and is the same as the millibar. So 1,000 mb and 1,000 Hpa are the same.

A two-and-a-half-foot tube is kind of awkward to keep around the house, and the need for a smaller and more practical device led to the development of the aneroid (without liquid) barometer. Instead of the expanding and shrinking of a mercury column, an expanding and contracting metal chamber does the work. Much of the air has been evacuated from the chamber, so slight changes in pressure around it cause it to respond by shrinking if the pressure increases or expanding if the pressure decreases. The metal chamber is attached to a pointer that indicates the pressure?the basic design of most barometers, including the home variety. A barograph (shown in the following figure) allows the pressure to be recorded on a rotating drum so that a time series analysis of pressure can be made. This works similar to a thermograph.
By the way, altimeters work just like barometers. Because the pressure decreases with height, these instruments are marked off in meters or feet rather than millibars or inches. The pressure drop with elevation is proportional to the change in height.

Barometer by farproc
The first barometer was invented in 1643. The mercury barometer is considered to be the oldest type of the barometer and it was invented by the Italian physicist Evangelista Torricelli.
He was conducting the barometric experiments by using the tube of water. Thus, the barometric pressure was helping to make more precise weather forecasts.
Nowadays technologies stepped far ahead of those first devices and even your smartphone can measure this barometric in seconds. Of course, the sensors themselves are rarely installed in the phone itself, usually the app transmits the information from the satellites and so on.
However, this app allows you to determine the pressure with the internal sensor, even though everything depends on your device. Nowadays most smartphones have weather sensors, so it will probably work.
The app itself is extremely simple – there is just a barometric indicator and that’s it. This fact makes this app extremely lightweight. If you were looking for the barometer app that is simple and that is able to work in the offline mode, this one is a good choice.
What is this?
This is the only web application dedicated to showing barometric pressure histories, forecasts and maps for any location in the world.
Who is this for?
Humans: Barometric pressure fluctuations can lead to migraine headaches, joint pain, arthritis symptoms, and blood pressure changes among other physical changes in the human body. Some people can predict weather patterns due to their bodies’ responses to changes in pressure. It can help to know in advance when the pressure will change in order to make lifestyle or medication adjustments beforehand, which is where this forecast graph can be helpful!
Meteorologists: Barometric pressure, also known as atmospheric pressure, is a leading indicator for inclement weather. Generally, low pressure systems are associated with cooler temperatures, precipitation, wind and storms.
Fishermen: Some fish respond to changes in barometric pressure and can change their level of feeding activity when pressure is dropping. Thus, fishermen might avoid fishing when pressure is dropping and seek out times to fish before or after those periods.

Barometer & Altimeter
Barometer and Altimeter is a simple application for measuring atmospheric pressure and altitude.
The application uses:
- built-in GPS,
- built-in pressure sensor / barometer (if the device does not have a barometric sensor, application retrieves atmospheric pressure data via the Internet from the nearest meteorological station),
- automatic altitude and atmospheric pressure calibration algorithm, based on data from local meteorological stations.
Barometer and Altimeter features:
- accurate height measurement above sea level (from GPS and other sensors),
- accurate measurement of barometric pressure (if the device is equipped in pressure sensor and check data available online)
- GPS coordinates, name of location, country
- information and current weather data from your local weather station (if available).
- outside temperature,
- wind speed,
- humidity, hygrometer (if device is equipped with appropriate sensors).
Exemplary uses of a barometer or altimeter tracker:
- health and medical - by monitoring the atmosteric pressure, you can be prepared for pressure jumps, headaches, migraine and malaise,
- for fishermen and anglers who fishing and sailing - monitoring the atmospheric pressure and weather you can increase the chances for good fishing,
- sportsmen and tourists,
- for determining, predicting and checking weather, air temperature, wind speed,
- to check the location,
- for pilots for check pressure and altitude,
- sailors, seamans and surfers can check the wind.
Using this barometeter tracker is simpler than using an aneroid or mercury barometer. Our Barometer and Altimeter tracker are free, easy to use, simple and handy.
Warning! Some portable devices (tablets, phones, smartphones) do not have a built-in pressure sensor. On these devices, the measurements may be less accurate as they will be based on data from the local meteorological stations.
We are constantly developing this app, if you see something that can be improved send us on [email protected] If you like this app, rate it for 5 stars.
Enjoy and have a good time with this app!
