how did antoine Lavoisier contributed to weather?

Answer 1

Good question. And as a matter of fact Lavoisier did make a few contributions to the science of meteorology. Meteorology was his second speciality. When he was twenty, he had begun making barometric observations in his residence on the rue du Four-Saint-Eustache, and he continued this activity all his life, as many meteorologists such as myself do to this day. In 1776, he carried out a comparative study of the lowest temperature observed during that winter (-14°) with that of the winter of 1709 (-15° 1/2); the data collected by the thermometer devised by Réamur (1683-1757) in 1732 were not in agreement with those obtained with more recent inventions: it was the occasion for him to define precise rules for the fabrication and graduation of thermometers and to deposit twelve standard models at the Academy of Sciences.

In 1781, studying natural electricity and the formation of thunder, he demonstrated with Laplace and Volta that hydrogen, nitiric oxide, carbon dioxide and water vapor, in passing from the liquid to the vapor state emitted electrical charges measurable by the electrometer. With Benjamin Franklin (1706-1790), he installed lightening rods on the roof of Saint-Paul's Church.

He considered weather forecasting to be almost as difficult an art as medicine: one needed daily measurements of atmospheric pressure, the velocity and direction of winds at different altitudes and the hygrometric state of the air. He created a network of correspondents in France and Europe and selected barometers and wind gauges. "With all this information," he wrote, "it is almost always possible to predict one or two days in advance, within a rather broad range of probability, what the weather is going to be; it is even thought that it will not be impossible to publish daily forecasts which would be very useful to society." (Lavoisier, Oeuvres, vol. III, p. 771.)

Much of this history is not only on the net but is part of several books of the past two decades which deal with the history of this science.

Answer 2

Lavoisier is known as the Father of Chemistry. Among many other discoveries he showed that the popular idea of Phlogiston was wrong and that the air contained oxygen. He also demonstrated that water was made of oxygen and hydrogen. Apart from that, he made no contributions towards an understanding of the weather, the great moves forward in that discipline did not start until the 19th century.
