Why is Liupanshui called the cool capital?

China Meteorological Society organized twelve expert committees, including China Academy of Sciences, Peking University, State Environmental Protection Administration, China Meteorological Bureau, Chinese Academy of Meteorology, China Tourism Publishing House, Beijing Meteorological Bureau and meteorological bureau of guizhou province, to demonstrate "Liupanshui, the cool capital of China" from three aspects of meteorology, environmental protection and medicine, through the analysis of climate data, air quality monitoring, the analysis of the influence of climate on diseases, and the observation of ultraviolet negative ions and meteorological sounding. This is the information obtained by the reporter at the demonstration achievement conference of "China Liangdu Liupanshui" held today. \ xd \ xd \ Liupanshui has an average altitude of 1,75m and an annual average temperature of 13℃-14℃. There is no "summer" in weather climatology. In July, August and September, when the temperature was the highest, the average temperature was 19.8℃, and the extreme highest temperature in history was only 31.2℃. According to the domestic standard of human comfort, the detailed statistical analysis of the climate data of Liupanshui city center from 1971 to 2 shows that people feel cool and comfortable in Liupanshui city for more than 96% of the time. According to the relevant personnel of Liupanshui Meteorological Bureau, Liupanshui is located in the intersection of water vapor circulation in the Bay of Bengal, cold air circulation in Siberia and subtropical high circulation in the Pacific Ocean, with abundant rain and suitable temperature. Although it is located on the plateau above 18 meters above sea level, the ultraviolet radiation is weakened by the atmospheric clouds with a height of 1 meters and a humidity of 7%, which makes the ultraviolet radiation moderate. \xd\\xd\ At present, Liupanshui can receive 3, to 4, tourists at the same time, but the level is not high. In order to improve the reception level, Liupanshui is prepared to develop the hotel construction in the middle and high-end direction, and strive to build three four-star hotels in about three years and five-star hotels in five years. On the highway side, there are Zhongshan Avenue, which is 2 kilometers long and 4 meters wide, Liangdu Avenue and Renmin Road, which are being rebuilt, and Wumeng Avenue, which is to be built next. In addition, Liupanshui City is also striving to build a feeder airport to build a celestial ground line for Liupanshui's tourism development. \xd\\xd\ According to the relevant leaders of Liupanshui City, Liupanshui City will strengthen its publicity efforts to promote "China as a cool capital" to the whole country and even the whole world, and formulate a set of publicity programs. In addition to branding CCTV, it will conduct media publicity irregularly during the hot summer, vigorously publicize the characteristics of the cool capital in a targeted manner, and add cultural factors.
