As the saying goes, "A mountain has four seasons, ten miles of different days". Will it snow during the Winter Olympics? What should I do if there is a strong wind? What the meteorological work of the Winter Olympics mainly does... As one of the important guarantee contents of the Winter Olympic Games, especially the snow projects in outdoor mountainous areas, the meteorological service guarantee of the Winter Olympics has attracted much attention. During the competition, in addition to sports equipment and athletes' own level, differences in natural conditions such as wind speed, wind direction, temperature, humidity, visibility and snow quality will directly affect the schedule arrangement and athletes' competition performance and competition safety, which puts forward higher requirements for the refinement of meteorological forecasting. It is also worth mentioning that the Beijing Winter Olympics is the only one held in the past 20 years under the conditions of continental winter wind and climate, and the possibility of high winds, low temperatures and other weather in the mountain arena is higher than that of previous Winter Olympics.

For the first time, the organization and implementation of multi-dimensional meteorological comprehensive observation experiments in winter under complex terrain in China's mid-latitude mountainous areas, and according to this, 441 sets of modern meteorological detection facilities were built in Beijing, Yanqing and Chongli, Hebei and surrounding areas, effectively improving the comprehensive meteorological monitoring capabilities of the Winter Olympics area; for the first time, it had the ability of "100 meters and minutes" accurate forecasting, and built a resolution of 500 meters in the Beijing-Tianjin-Hebei region and 100 meters in the core area of the Winter Olympic mountain arena. The China Meteorological Administration Beijing rapidly updated the circular numerical forecasting system for 10 minutes to effectively improve the forecast accuracy of the Winter Olympic Games... With the Beijing Winter Olympic Games and the Winter Paralympic Games approaching, the "hard-core" report card of meteorological science and technology innovation to achieve "two firsts" will not only effectively improve the meteorological service guarantee capabilities of the Winter Olympics, but also let us once again witness the Chinese scientific and technological strength behind the Olympic Games.
Polish the "sharp weapon" for the meteorological forecast of the Winter Olympics, and form a meteorological data service pattern of interconnection, data sharing and mutual backup... From the "Science and Technology Winter Olympics", we will gain the confidence and confidence to successfully host the Olympic Games and promote high-quality development, so that we can march towards the future together.
