C. H. D. Buys Ballot

Christophorus Henricus Diedericus Buys Ballot (October 10, 1817, Kloetinge – February 3, 1890, Utrecht) was a Dutch chemist and meteorologist after whom Buys-Ballot's law and the Buys Ballot table are named.

The son of a Dutch Reformed minister, Buys Ballot attended the Gymnasium at Zaltbommel and the Hogeschool (now University) of Utrecht. Utrecht University ( Universiteit Utrecht in Dutch) is a University in Utrecht, The Netherlands. After receiving his doctorate in 1844, he became lecturer in mineralogy and geology at Utrecht; he added theoretical chemistry in 1846. Year 1844 ( MDCCCXLIV) was a Leap year starting on Monday (link will display the full calendar of the Gregorian Calendar (or a Leap year Mineralogy is an Earth Science focused around the Chemistry, Crystal structure, and physical (including optical) properties of Minerals Geology (from Greek γη gê, "earth" and λόγος Logos, "speech" lit Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties For the game see 1846 (board game.

Buys Ballot tested the Doppler effect for sound waves in 1845 by using a group of musicians playing a calibrated note on a train in the Utrecht-Amsterdam line. The Doppler effect (or Doppler shift) named after Christian Doppler, is the change in Frequency and Wavelength of a Wave for

Buys Ballot is best known for his accomplishments in the field of meteorology, specifically the explanation of the direction of air flow in large weather systems. Meteorology (from Greek grc μετέωρος metéōros, "high in the sky" and grc -λογία -logia) is the Interdisciplinary Furthermore, he founded the Royal Dutch Meteorological Institute in 1854 and he remained its chief director until his death. Year 1854 ( MDCCCLIV) was a Common year starting on Sunday (link will display the full calendar of the Gregorian Calendar (or a Common year He was one of the first to see the need for international cooperation, and in 1873 became the first chairman of the International Meteorological Committee, a precursor of the World Meteorological Organization (WMO).

Buys-Ballot's law states that if a person in the Northern Hemisphere stands with his back to the wind, the low atmospheric pressure is found to his left. In Meteorology, Buys Ballot's law may be expressed as follows In the Northern Hemisphere, stand with your back to the Wind; the low pressure Northern Hemisphere is the half of a Planet that is North of the Equator —the word hemisphere literally means 'half ball' His main research effort in meteorology went into examining long-time series for regularities; he was more concerned with establishing the regularities than in explaining them. He made no contributions to the theory of meteorology which is perhaps surprising given his training in physics. The contrast with his American contemporary, William Ferrel, who discovered Buy-Ballot's law slightly earlier, is striking. This page is about the meteorologist for the Comedian, see Will Ferrell.

Buys Ballot devised a tabular method for investigating periodicity in time series. In Statistics, Signal processing, and many other fields a time series is a sequence of Data points measured typically at successive times spaced at (often In 1847 he used the table now named after him to determine the period of the sun's rotation from daily observations of temperature in the Netherlands from 1729 to 1846. Year 1729 ( MDCCXXIX) was a Common year starting on Saturday (link will display the full calendar of the Gregorian calendar (or a Common
