This document discusses the history of meteorology and inventions of weather instruments. It covers topics such as the scientific study of meteorology beginning in the 18th century and breakthroughs in the 19th century with observing networks. Key weather instruments are also summarized, including the thermometer measuring temperature, aneroid barometers measuring air pressure, rain gauges measuring precipitation, hygrometers measuring humidity, and barometers being invented by Torricelli in 1643 to measure air pressure. The document also discusses different scales in meteorology from micro to synoptic to global scales based on spatial and temporal scopes.
