To visit the museum, you need to go through the office area of Jiangsu Meteorological Bureau and walk up the Panshan Highway. After entering the gate, there is a reservoir, and a long pole 10 meters high stands on the middle platform. At first glance, I thought it was a flagpole, but on closer inspection, the lower end of the long pole is flawless white jade, the barrel is engraved with exquisite dragon and phoenix patterns, and the upper end is black iron. A couple stood on the top plate of the pole and turned with the wind. It turns out that this is the couple anemometer that appeared 800 years ago, and people use it to measure the wind direction. Further inside, a path leads to a secluded place. There are reliefs on the nearby gable, depicting the development of China's meteorological cause. There are several statues standing on the lawn ahead. Lu Shang, Guan Zhong, Dong Zhongshu, Wang Chong, Shen Kuo, Li, Qin, etc. are all meteorologists of past dynasties. The equatorial sundial of the ancient observatory moved forward again in the Yuan Dynasty, and a building to restore the ancient observatory appeared in front of us. The bronze statue of Zhu Kezhen, the founder of modern meteorology in China, stands in the square in front of the ancient astronomical observatory. Zhu Kezhen is the founder of Arctic Pavilion Meteorological Observatory. He devoted his life to the meteorological cause of his motherland. 1on the morning of February 6th, 974, dying Zhu Kezhen propped himself up and turned on the knob of the radio to listen to the weather forecast. Then, he put on his reading glasses and wrote a small line in his notebook:1February 6, 974, the highest temperature-1℃, the lowest temperature -7℃, easterly wind 1-2, sunny to cloudy. This is the last meteorological diary left by Zhu Kezhen. At the last moment of my life, I still haven't forgotten my job responsibilities. This spirit is admirable. The ancients thus determined that the four seasons and solar terms went down from the other side of the ancient observatory, which was a half-moon courtyard built on the mountain. This is the indoor exhibition hall of the museum. There is a plaque hanging at the entrance, which reads "China Arctic Museum Meteorological Museum", which was inscribed for Zheng Guoguang, then director of China Meteorological Bureau. The museum is divided into four theme exhibition halls: ancient meteorology, modern meteorology, modern meteorology and modern meteorological science and technology, with a construction area of about 1000 square meters. Show major meteorological historical events, the evolution of meteorological instruments, the changes of meteorological institutions and the blueprint for the development of meteorological science and technology in various forms such as objects, models, pictures, historical materials and images. The ancient meteorology in China can be divided into Stone Age and Legendary Historical Age, including Xia, Shang and Zhou Dynasties, Spring and Autumn and Warring States Period, Qin and Han Dynasties, Three Kingdoms to Ming Dynasty and early Qing Dynasty, which recorded the progress of ancient people in the changing environment. In front of the model of the ancient observatory site, what interests me most is what the Taosi Observatory looks like after restoration. In 2003, the oldest observatory in the world was discovered in the archaeological excavation of the sacrificial site of Duyaotao Temple in Shaanxi, which was more than 500 years earlier than the Stonehenge Observatory in Britain. Taosi Observatory consists of 13 rammed earth columns in a semicircle with a radius of10.5m and an arc length of19.5m. Observe the sunrise direction from the observation point through the gaps in the earth columns, determine the seasons and solar terms, and arrange farming. For example, from the second slit, the sunrise is the winter solstice, from the 12 slit, the sunrise is the summer solstice, and from the seventh slit, the sunrise is the vernal equinox and the autumnal equinox. Friends who have seen Chang 'an for the longest day should be familiar with the sundial in the exhibition hall. It is an instrument that uses the change of the position of the sun shadow to measure time, which evolved from a standard watch. The brick surface is parallel to the earth's surface (equatorial plane of the earth), and the copper pointer in the center of the brick surface is parallel to the earth's rotation axis. There are twelve o'clock engraved on the coffin surface, and the time indicated by the projection of the needle shadow on the coffin surface is the sun time at that time. From meteorological powers to powerful meteorological countries to modern meteorological institutions, it will be found that since the Republic of China, people of insight and customs, aviation, schools, farms and other systems have successively established meteorological stations, and meteorological work has been widely carried out. 1906, industrialist and educator Zhang Jian built a waiting room in Nantong Museum, Jiangsu Province. 19 17, he founded Junshan Meteorological Observatory, the earliest private meteorological observatory in the history of China, conducted meteorological observation and forecast, published reports in Chinese and English, and communicated with more than 100 meteorological stations or institutions in more than 40 countries and regions around the world, which can be said to be the first to open the atmosphere and lead the new era. In the exhibition hall of modern meteorological science and technology, there is a special device, standing in front of it, as if in the vast universe, looking at our earth. This is a sphere located in the center of the exhibition hall. It is called SOS (Spherical Science Exhibition System). It is actually a large 360-degree video playback system. The computer controls four high-performance projectors, and the display system projects the picture onto a spherical screen with a diameter of 1.73m for people to watch. By rotating this "earth", we can intuitively observe the laws and historical data of temperature, ocean current, wind, atmosphere and other activities around the world, which is simply a meteorological dictionary containing thousands of data.
