The document discusses the history and invention of key weather instruments. It describes how meteorology emerged as a science with the development of instruments like the barometer in 1643 to measure air pressure, the thermometer in the early 1600s, and the hygrometer in the mid-1600s to measure humidity. Anemometers for measuring wind speed were also invented in the 1600s-1700s. These early instruments allowed for systematic weather observation and prediction of weather patterns.
