What meteorological instruments were invented in ancient China?

China has long used meteorological instruments to observe weather conditions, and was the first country to invent anemometers and rain gauges. Zhang Heng of the Eastern Han Dynasty invented the waiting seismograph in 132. It stands a 5-foot (about 16.7 meters) high pole with a rotatable copper bird on it. According to the direction in which the bronze bird rotates with the wind, we can see what the wind direction is. This is similar to the waiting for chickens recorded in foreign books in 12 century, and it is later than the bronze bird 1000 year.

There was also a wind flag in ancient China, which was tied with a Jason Chung and hung on a high pole. You can tell what wind is blowing by looking at the direction in which the flag is blowing. This is similar to the modern wind pocket.

China first used the rain gauge. There is a passage in Shu Shu Jiu Zhang that describes the situation from 65438 to 0247 AD in the Song Dynasty. The rain gauge is uniform in size, with a cylinder diameter of 14 cm and a copper rain gauge.

However, for a long time, apart from using a few meteorological instruments, we mainly rely on objects and astronomical phenomena to forecast the weather.

/kloc-in the 0/7th century, scientists invented barometers and thermometers, and then successively invented thermometers and anemometers, so that the weather conditions in a certain place can be quantitatively determined.
