To say that the lunar calendar February is the most grand festival
It is not today's "dragon head"
At the beginning of the mid-spring month of each year (Dou Zhi Zheng Dong).
The "Dragon's Horn" rises from the eastern horizon
Hence the name "Dragon Heads Up"
Legend has it that the dragon looked up this day
The Dragon King, who is in charge of the clouds and rain, will wake up
Since then, spring has returned to the earth and the rain has increased
It's spring plowing
The dragon has a long history, and the Yuan Dynasty began to widely spread the second day of the second month of the lunar calendar as a national festival. On this day, the folk held various celebration activities around the "dragon worship", such as dragon worship, shaving of the head, sacrifice, smoked insects, fried beans, etc., in various forms, all of which represented the people's ardent expectations for the wind and rain, the exorcism of evil spirits, and the abundance of grain in the agricultural era.
The mainland has been a big agricultural country since ancient times, agricultural development is highly dependent on weather changes, then there was no advanced scientific and technological support, the ancients predicted the weather based on the sun, moon, stars, wind and clouds and lightning, to provide services for agricultural production.
Weather forecasts of the ancients
According to legend, according to the cyclical operation of the sun, Fuxi deduced gossip to predict the weather and guide the original farming activities.
During the Shang and Zhou Dynasties, divination was prevalent, and "burning turtle shells" became one of the means of predicting weather changes, and the words gua and yao in the Zhou Yi also contained examples of predicting weather changes.
In the pre-Qin period, the piano was used to predict the weather, if the plucked strings heard a heavy tone, it is likely that the wet bed caused the strings to become loose, indicating that the air humidity is large, and the wind and rain are coming.
By the Han Dynasty, breakthroughs were made in weather observation. In the book "Huainan Zi" compiled by Liu An, the king of Huainan in the Western Han Dynasty, the twenty-four solar terms were most fully expressed, calculated and recorded for the first time, and "there is no precedent for farming, all rely on the solar terms" and thus inherited;
In addition, after repeated observation and practice of daily life, there are also many weather proverbs handed down in ancient times, such as "there are purple clouds in the direction, thunderstorms in the afternoon", "clouds go east, gusts of wind; clouds go west, cloaked" and so on, reflecting the experience of working people in predicting weather changes.
However, due to the limitations of ancient productivity, there are many deficiencies in people's prediction of weather, with subjective speculation, and it is easy to predict inaccurately.
With the development of productive forces and the advancement of science and technology, human beings can use more advanced means to make more accurate predictions of weather. Today, under the wave of digitalization, the Meteorological Bureau has also embarked on a transformation journey to help the realization of smart meteorology and provide people with better meteorological services.
Promote meteorological modernization with science and technology
Meteorological services involve all fields of social and economic development, including agriculture, transportation, construction, commerce, tourism and other trillion-level industries, so the digital transformation of meteorological service business has become an urgent requirement for comprehensively promoting meteorological modernization and accelerating the improvement of meteorological modernization.
In this context, Dell Technologies, together with Digital China Cloud Technology Co., Ltd. (hereinafter referred to as "Shenzhou Yunke"), cooperated with a provincial meteorological bureau in China to build a comprehensive management information system (CMIS system) of the meteorological bureau to promote the construction of customers' comprehensive meteorological service capabilities.
The provincial meteorological bureau application requires the storage and management of meteorological observation data and core products throughout the life cycle, the commonly used meteorological data needs all online services, the real-time application data needs to achieve sub-second response, and the historical data query and analysis need to achieve second-level response, truly realizing the direct support of the application system.
Dell Technologies offers solutions including PowerEdgeR940xa and R740 servers and SC7020F all-flash arrays.
Prevent and reduce disasters, and protect the first line of defense
Disaster prevention and mitigation meteorology comes first, and meteorology must play the role of the first line of defense in disaster prevention and reduction.
In 2020 alone, a provincial meteorological bureau issued more than 10,000 warnings of various types through the emergency early warning information release system, and the amount of information increased by 20% over the previous year.
The cooperation between Shenzhou Yunke and Dell Technology to promote the construction of meteorological modernization and upgrading projects includes the construction and operation and maintenance management of the emergency early warning information release system, and the system database uses 27 Dell PowerEdgeR940xa and R740 servers.
Dell PowerEdgeR940xa server with Intel Xeon Scalable processors, optimized for performance and price/performance, unlocking the potential of scalable performance in the data center.
The deployment and implementation of the system has improved the calculation and processing capabilities of satellite, radar, GNSS and other data of a provincial meteorological bureau, and promoted the upgrading of regional meteorological measurement technology, the spatio-temporal resolution of numerical weather forecasting has been increased to 1-2 hours, the advance amount of strong convective weather warning can be 50-60 minutes, and the accuracy of heavy rain and blizzard forecasts ranks at the forefront of the industry, truly building the "first line of defense" for disaster prevention and reduction.
410% increase in data service assurance capabilities
For the Meteorological Bureau, whether it is the collection and dynamic update of metadata information of meteorological data, or the collection of hydrographic, lithosphere, biosphere and other related scientific and social, economic, environmental and other thematic data, or the construction of data resource identifier system, it is necessary to establish an efficient data storage platform.
After a comprehensive investigation, the provincial meteorological bureau introduced the SC7020F all-flash array, which is responsible for rapidly integrating natural and environmental basic data such as surface conditions and ecological resources, drawing meteorological basic information maps, and building multi-grid meteorological "one network" for the province.
In the end, SC7020F fully realized the minute-level transmission, processing, storage sharing and application of meteorological real-time data, met the needs of forecasting business system, meteorological services and meteorological scientific research, and improved the data service guarantee capability of the Meteorological Bureau by 410%.
In this regard, Chen Renhui, the general leader of the Shenzhou Yunke project, said:
“
The number of meteorological data files is large, the data exchange efficiency is high, and the overall throughput is large, and the choice of SC7020F full flash storage can meet all the requirements of meteorological professional data storage system and promote the intensive development of business.
”
From ancient times to the present, human beings have been tirelessly exploring meteorological changes, the process of understanding nature is wonderful and infinite, even if human beings can not influence the laws of nature, but can use science and technology to have a more accurate understanding of nature, and follow the trend to promote the development of productive forces.
As the world's leading IT solutions provider, Dell Technologies' product solutions are supporting multiple industries such as agriculture, manufacturing, medical care, finance, etc. Dell Technologies has always adhered to the mission of promoting human progress with technological innovation, and empowering your business with more advanced technology.
