The history of meteorology

and the invention of weather instruments

The word ‘meteorology’ was coined from a research book called ‘Meteorologica’ which was written by Aristotle, a Greek scientist and philosopher. This early work described the science of earth like its geology, elements, hydrology, seas, wind and weather.

In the modern term, the term meteorology explains a complete science. It is for understanding the dynamics of atmosphere and forecasting weather phenomena like hurricanes and thunderstorms.

Weather forecasting was practiced since the beginning of time with more or less accuracy. Historical records show several examples of weather predicting methods based on observing surrounding elements.

Sky is undoubtedly the first indicator used in meteorology its cover and nature of clouds provides clues of the upcoming temperature and weather. The wind factor is also important and is associated with temperature and often rains. Animals and birds are also known to give indications about the future weather.

Scientists across the world since ancient times have tried to understand the meteorological phenomena like wind and rain. Many instruments for measuring wind power, humidity and rain were invented in the early 15th century.

During the 17th century, several discoveries tipped in favor of scientific meteorology. A device to measure temperature was invented by Galileo Galilei and the factor that atmospheric pressure was linked to altitude was discovered by Blaise Pascal. The invention of barometer by Evangelista Torricelli is significantly the most important discovery. It is still in use today which indicates atmospheric pressure changes that are linked with the future weather changes.

There are also other methods which have been evolved. Meteorology is a lot related with cycles and their analysis which was what Fernando II de Medici wanted to prove.

He carried out a very determined program in 1654 for recording weather patterns in different European cities with a view to compile data and make their analysis.

When the theory of thermodynamics and atmospheric pressures were adapted, no real changes were important for understanding meteorology. In recent times, focus has been given on meteorological tools for its improvement and attaining better accuracy results.

A tremendous boost was given to meteorology because of the technology in two ways. The first is the ability to communicate results and analysis with timing, it was made possible due to the invention of telegraph. The second is the ability of probing skies with using balloons, satellites and radars.

Meteorology is a part of our everyday lives. People are kept updated about the changing weather with dedicated channels and mobile devices. The science is still progressing and is an important element of the economy with many industries like agriculture and civil aviation depending on it.

SOME WEATHER INSTRUMENTS

AND THIR FUNCTIONS

AnemometersLet the winds blow and you'll know how fast with our selection of anemometers. Whether you're a storm lover, own an RV, or live in a gust- or tornado-prone region, you'll find these gauges to be reliable as well as fascinating. Choose wall mounts or desktop models that come complete with cabling and rooftop sensors. Dials are attractively designed in metals and woods.

BarometersWhether you're looking for a fully

functional weather station or simply wish to follow temperature and air pressure, this selection of barometers is sure to please. They're elegant and crafted to traditional standards and with mechanisms that are crafted by the latest scientific advances. Fine woods and brass finishes will complement any decor, whether as a tabletop or wall display.

Thermometers You don't have to be a weather

expert to enjoy this collection of hygrometers. You can easily compare humidity, barometric pressure, and temperature with any of these finely crafted pieces in woods and brass finishes. They're decoratively appealing for display, including the famous Howard Miller designs, and will be beautiful, accurate, and long-lasting accents for any type of decor from traditional to contemporary.

Hair Hygrometer Water-absorbing properties of hair

were used in 1783 to develop the first hygrometer, an instrument for measuring humidity. This old-fashioned hygrometer was calibrated by first determining the length of a hair at total dehydration and at total saturation, or 0 percent humidity and 100 percent humidity, respectively. Relative humidity then could be calculated by using these two set points.

Sling Psychrometer As an instrument for measuring

humidity, the sling psychrometer came into use during the 19th century. This old-fashioned weather instrument used two identical mercury thermometers mounted on a wooden paddle. The bulb of one of the thermometers is wrapped in wet absorbent materials. A person then whirls (slings) the handle around through the air and the thermometer with the wet bulb cools rapidly compared to the other due to evaporation properties of water. The temperature difference between the two thermometers can then be converted to relative humidity.

Weather vane - A weather vane, also known as a wind vane or weathercock, is an instrument for showing the direction of the wind. They are typically used as an architectural ornament to the highest point of a building. Although partly functional, weather vanes are generally decorative, often featuring the traditional.

Weather station - A weather station is a facility with instruments and equipment to make observations of atmospheric conditions in order to provide information to make weather forecasts and to study the weather and climate. The measurements taken include temperature, barometric pressure, humidity, wind. 

Weather derivatives - Weather derivatives are financial instruments that can be used by organizations or individuals as part of a risk management strategy to reduce risk associated with adverse or unexpected weather conditions. The difference from other derivatives is that the underlying asset (rain/temperature/snow).. 

WHAT METEOROLOGIS

T(WEATHER MAN) SAY?

Perhaps the most direct way in which people benefit from earth science research is through daily weather prediction. Weather systems thousands of miles away have an effect on you right here at home. Earth science satellites provide up-to-the-minute information about weather patterns across the entire world, allowing meteorologists to forecast what's headed your way.

More than just images of clouds, meteorologists compare temperature readings, winds, atmospheric pressure, precipitation patterns, and other variables to form an accurate picture of our climate. From past readings, meteorologists are able to draw conclusions and make predictions about how our climate will translate into local weather every day.

They can also develop computer models that predict how climate and weather may vary in the future as a result of human activity. Meteorologists also carry out basic research to help us understand the way the atmosphere works, ranging from why hurricanes and tornadoes form when and where they do, to why the ozone hole formed over the Antarctic in the spring.

They use satellites, aircraft, ships, and balloons to take the data needed to help understand, document, and predict weather and climate.

If understanding the atmosphere around you, helping to predict how it behaves - both today and in the future - sounds interesting to you, learn more about meteorology!
