Barometer Definition and Function (Science)

Barometer Definition and Function (Science) The barometer, thermometer, and anemometer are important meteorology instruments. Learn about the invention of the barometer, how it works, and how its used to forecast weather. Barometer Definition A barometer is a device that measures atmospheric pressure. The word barometer comes from the Greek words for weight and measure. Changes in atmospheric pressure recorded by barometers are most often used in meteorology for forecasting weather. Invention of the Barometer Usually youll see  Evangelista Torricelli credited with inventing the barometer in 1643,  French scientist Renà © Descartes described an experiment to measure atmospheric pressure in 1631 and Italian scientist  Gasparo Berti constructed a water barometer between 1640 and 1643. Bertis barometer consisted of a long tube filled with water and plugged at both ends. He placed the tube upright in a container of water and removed the bottom plug. Water flowed from the tube into the basin, but the tube did not completely empty. While there may be disagreement over who invented the first water barometer, Torricelli is certainly the inventor of the first mercury barometer. Types of Barometers There are several types of mechanical barometer, plus now there are numerous digital barometers. Barometers include: water-based barometers - most often consists of a sealed glass ball that is half-filled with water. The body of the ball connects below the water level to a narrow spout, which rises above the water level and is open to the air. The water level of the spout rises when atmospheric pressure is lower than it was when the glass ball was sealed and drops when air pressure exceeds the pressure when the ball was sealed. While not particularly precise, this is a simple type of barometer easily constructed at home or in a lab.mercury barometers - uses a glass tube that is closed at one end, standing in a mercury-filled reservoir that is open to air. A mercury barometer works on the same principle as the water barometer, but is much easier to read and more sensitive than a water barometer.vacuum pump oil barometers - liquid barometer that uses vacuum pump oil, which has an extremely low vapor pressureaneroid barometers - type of barometer which does not use liquid to measure pressure, instead relying on expansion or contraction of a flexible metal capsule barographs - uses an aneroid barometer to move a pen or needle to make a graph of pressure changesmicroelectromechanical systems (MEMS) barometersstorm glasses  or Goethe barometersmartphone barometers How Barometric Pressure Relates To Weather Barometric pressure is a measure of the weight of the atmosphere pressing down on the Earths surface. High atmospheric pressure means there is a downward force, pressure air down. As air moves down, it warms up, inhibiting the formation of clouds and storms. High pressure typically signifies fair weather, particularly if the barometer registers a lasting high pressure reading. When barometric pressure drops, this means air can rise. As it rises, it cools and is less able to hold moisture. Cloud formation and precipitation becomes favorable. Thus, when a barometer registers a drop in pressure, clear weather may be giving way to clouds. How To Use a Barometer While a single barometric pressure reading wont tell you too much, you can use a barometer to forecast changes in the weather by tracking readings throughout the day and over the course of several days. If the pressure holds steady, weather changes are unlikely. Dramatic changes in pressure are associated with changes in the atmosphere. If pressure suddenly drops, expect storms or precipitation. If pressure rises and stabilizes, youre more likely to see fair weather. Keep a record of barometric pressure and also wind speed and direction to make the most accurate forecasts. In the modern era, few people own storm glasses or large barometers. However, most smart phones are able to record barometric pressure. A variety of free apps are available, if one doesnt come with the device. You can use the app to relate atmospheric pressure to weather or you can track the changes in pressure yourself to practice home forecasting.

Affirmative Action - Research Proposal Example Secondly, non-minorities have perceived a reverse racism when chosen over for supposedly less qualified minorities. Thirdly, some individuals from a minority background might feel as though it is condescending to imply that they need extra help in order to succeed. Whatever problems that might exist in the system, there is no arguing that racism still does exist, and that some means are needed to counter-act this inherent disparity. Affirmative action can be a positive social program, but the program is almost necessarily imperfect. It can be continued to be adjusted and tweaked, but until it is no longer needed, there will always be controversy surrounding the issue. To first address opponents of affirmative action, the main argument states that it is merely reverse discrimination. This is more or less the â€Å"two wrongs don’t make one right† argument. To discuss it in more depth, opponents say that it is a program that, while attempting to deal with issues of inequality due to discrimination, merely discriminates against one group as opposed to another: â€Å"Affirmative action is designed to end discrimination and unfair treatment of employees/students based on color, but it in effect does the opposite. Whites who work harder and/or are more qualified can be passed over strictly because they are white† (Messerli, 2008). This, in effect, while attempting to counter-act the effects of racism and discrimination, will only create more difficulties in race relations because whites who are picked over for minorities on the basis of skin color will begrudge this decision; it seems as though affirmative action as a social progra m on its own would be unable to end racism and discrimination. Another argument states that while the issues that affirmative action attempts to deal with are at the level of society in general, i.e. the damage that a racist and discriminatory society in general has done to
