Air is "pushed" into the open end of a barometer when the pressure is higher, meaning the mercury closer to the closed end of the barometer - where the pressure is measured - will rise.

To make a record of the air pressure and how it's changing, and aneroid is connected connected with a device that records air pressure, making it an aneroid barograph. An aneroid is a flexible metal bellow that has been tightly sealed after having some air removed. Higher atmospheric pressures squeeze the metal bellows while lower pressures allow it to expand. The aneroid barograph consists of a slowly rotating cylinder with paper on it that can give up to a week's worth of air pressure records before new paper is needed. As you can see in the graphic above, a pen at the end of a lever attached to the aneroid moves up and down according to pressure changes and records the pressure on the paper wrapped around the cylinder.The aneroid barometer has some advantages over a Mercury barometer because it is much smaller and can also record a week's worth of data. The aneroid barometer is the heart of altimeters used in modern aviation.
By the process of ultra-filtration. At the proximal end of the capillary, you have pressure of about 30 mm of mercury. So the fluid leaves the capillary and enter the interstitial compartment. At the distal end of the capillary the pressure is about 15 mm of Mercury. The fluid in drawn in due to oncotic pressure at that end.
Air pressure does make quite a difference in weather. In this question, we are talking about high pressure areas and low pressure areas. In High Pressure areas, this doesn't allow for cloud formation, so we end up getting very nice weather. Low Pressure areas are the exact opposite, this allows for cloud formation, so we end up getting rainy weather. High Pressure Areas are represented with a blue H on a weather map. Low Pressure Areas are represented with a red L on a weather map.

A barometer is used for measuring atmospheric pressure. The barometer sealed on the top with an open bottom in order to allow air pressure to push down.

Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:
The Dial was created in 1840.
Dial Award ended in 1998.
The function of a manometer is to measure the pressure of a fluid, usually a gas or a liquid. It consists of a sealed tube filled with the fluid being measured, with one end open to the environment and the other end connected to the source of pressure. As the pressure changes, the fluid in the manometer rises or falls, allowing the measurement of the pressure.
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.
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
