History of Meteorology and Invention of Weather Instruments

  1. 1. ONLINE ANTIVITY 2By: Bobby joseasis<br />
  2. 2. METEOROLOGY<br />
  3. 3. METEOROLOGY<br /> is the scientific study of the atmosphere that focuses on weather processes and forecasting. There is also broad discussion of atmospheric physics and atmospheric chemistry, including such topics as air pollution, tropical cyclones, mid latitude weather.<br />
  4. 4. HISTORY OF METEOROLOGY<br />In 350 BC, Aristotle wrote Meteorology. Aristotle is considered the founder of meteorology. One of the most impressive achievements described in the Meteorology is the description of what is now known as the hydrologic cycle. The Greek scientist Theophrastus compiled a book on weather forecasting, called the Book of Signs. The work of Theophrastus remained a dominant influence in the study of weather and in weather forecasting for nearly 2,000 years. In 25 AD, PomponiusMela, a geographer for the Roman Empire, formalized the climatic zone system. Around the 9th century, Al-Dinawari, a Kurdish naturalist, writes the Kitab al-Nabat (Book of Plants), in which he deals with the application of meteorology to agriculture during the Muslim Agricultural Revolution. He describes the meteorological character of the sky, theplanets and constellations, the sun and moon, the lunar phases indicating seasons and rain, the anwa (heavenly bodies of rain), and atmospheric phenomena such as winds, thunder, lightning, snow, floods, valleys, rivers, lakes, wells and other sources of water. <br />
  5. 5. APPLICATION OF METEOROLOGY<br />
  6. 6. WEATHER FORECASTING<br />Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. Human beings have attempted to predict the weather informally for millennia, and formally since at least the nineteenth century.Weather forecasts are made by collecting quantitative data about the current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve.<br />
  7. 7. AVIATION METEOROLOGY<br />Aviation meteorology deals with the impact of weather on air traffic management. It is important for air crews to understand the implications of weather on their flight plan as well as their aircraft, as noted by the Aeronautical Information Manual<br />The effects of ice on aircraft are cumulative-thrust is reduced, drag increases, lift lessens, and weight increases. The results are an increase in stall speed and a deterioration of aircraft performance. In extreme cases, 2 to 3 inches of ice can form on the leading edge of the airfoil in less than 5 minutes. It takes but 1/2 inch of ice to reduce the lifting power of some aircraft by 50 percent and increases the frictional drag by an equal percentage. <br />
  8. 8. AGRICULTURAL METEOROLOGY<br />Meteorologists, soil scientists, agricultural hydrologists, and agronomists are persons concerned with studying the effects of weather and climate on plant distribution, crop yield, water-use efficiency, phenology of plant and animal development, and the energy balance of managed and natural ecosystems. Conversely, they are interested in the role of vegetation on climate and weather.<br />
  9. 9. HYDROMETEOROLOGY<br />Hydrometeorology is the branch of meteorology that deals with the hydrologic cycle, the water budget, and the rainfall statistics of storms. A hydrometeorologist prepares and issues forecasts of accumulating (quantitative) precipitation, heavy rain, heavy snow, and highlights areas with the potential for flash flooding. Typically the range of knowledge that is required overlaps with climatology, mesoscale and synoptic meteorology, and other geosciences. <br />
  10. 10. NUCLEAR METEOROLOGY<br />Nuclear meteorology investigates the distribution of radioactive aerosols and gases in the atmosphere<br />
  11. 11. MARITIME METEOROLOGY<br />Maritime meteorology deals with air and wave forecasts for ships operating at sea. Organizations such as the Ocean Prediction Center, Honolulu National Weather Service forecast office, United Kingdom Met Office, and JMA prepare high seas forecasts for the world's oceans.<br /> <br />
  12. 12.  HISTORY OF WEATHER KNOWLEDGE<br />For most of human history, weather predictions had to be made using pure observation. Babylonians attempted to predict short-term weather changes based on the appearance of clouds and optical halos, and Aristotle wrote a philosophical treatise called "Meteorologica" that included detailed theories on the formation of rain, clouds, lightning and many other weather-related phenomena. It was not until the Renaissance that weather instruments were finally invented through the gains of technological advancements and the formulation of accurate theories about the weather. In the 20th century, more refined technology like weather balloons and Doppler instruments helped to make weather measurement quicker and more accurate.<br />
  13. 13. WEATHER INSTRUMENTS<br />Weather instruments have a long, rich history that may be charted against the growth of science itself. The advent of weather instruments was a time when inventors could be experts in many scientific fields---Galileo, for example, helped lay down the framework for modern astronomy but also found the time to experiment with thermometers. Starting with a mere idea, the design of these specialized instruments graduated to robust theory, experimental application and progressive refinement over time.<br />
  14. 14. INVENTION OF WEATHER INSTRUMENTS<br />
  15. 15. HYGROMETER<br />One of the first known designs of the hygrometer was written down in approximately 1450 AD by Nicholas of Cues, who described how to measure the humidity of air. An early hygrometer was built by Leonardo da Vinci and later in 1663 by Robert Hooke, using a piece of hair that contracted or expanded depending on the degree of humidity present. Inventions in 1783 by Horace-Bénédict de Saussure (who used human hair) and in 1820 (when J. F. Daniell used ether in glass tubes) refined the hygrometer.<br />
  16. 16. THERMOMETERS<br />Thermometers were progressively developed over time by inventors such as Cornelius Drebbel, Robert Fludd, SantorioSantorio and, most notably, Galileo Galilei, who in 1592 invented a thermoscope that reacted to changes in temperatures. In 1612, Santorio put a scale on the thermometer so that it began to resemble its more modern permutations, but it wasn't until 1714 that Daniel Gabriel Fahrenheit replaced the alcohol in thermometers with mercury and developed a more accurate measurement, later to be followed by Anders Celsius and Sir William Thomson (who invented the Kelvin scale) with their own measurements of temperature.<br />
  17. 17. BAROMETERS<br />Evangelista Torricelli is credited with inventing the barometer in 1643 to measure air pressure, but both Giovanni Battista Baliani in 1630 and René Descartes in 1631 had postulated a version of the barometer even earlier than that. GasperoBerti, who had heard from Galileo about the design written down by Baliani, attempted to experiment with water in a vacuum between 1639 and 1641 to explain why pumps would not draw water above a certain height. Torricelli, however, approached it from a different angle and recognized that air had weight; he also recognized that mercury in a barometer was a suitable replacement for water. Years later, Blaise Pascal and Florin Périer refined the design.<br />
  18. 18. ANEMOMETERS<br />Anemometers, which measure wind speed, were first described by Leon Battista Alberti in 1450, but the most familiar kind, the cup anemometer, was invented in 1846 by Dr. John Thomas Romney Robinson. The design was refined up until the 20th century: In the 1960s and 1970s, anemometers that used lasers or sonar to measure wind speed were developed.<br />
