The Paris Olympics are just around the corner! Fine weather service "escort" Chinese athletes
The opening ceremony of the Paris Olympic Games will be held at 1:30 am Beijing time on July 27. Far away at the China Meteorological Administration in Beijing, there is a group of people who quietly provide service for China's athletes - they are meteorologists.Outdoor sports such as shooting, archery, rock climbing and rowing are greatly affected by the weather, such as wind speed, wind direction, temperature and humidity, which have a great impact on the athletes' body sense and action play."The weather support is working very well." The State General Administration of Sport expressed its gratitude to the China Meteorological Administration after completing the Budapest leg of the Olympic Qualification Series.

Li Xiaolan from the weather Room of the National Meteorological Center often communicated with the Chinese sports delegation face to face or by video to clarify the impact of different meteorological factors on outdoor events: high temperature and high humidity weather brings challenges to athletes' physical fitness, and strong convection weather such as heavy rain brings risks to sports safety. Rock climbing is affected by high temperature and humidity, strong convection weather, shooting, archery, canoeing, rowing, sailing are more concerned about wind direction and wind speed.Understanding the specific needs of each sport for weather forecasting elements is the first step in ensuring weather for the Paris Games. As early as April this year, led by the Sports Information Center of the State General Administration of Sport, the Institute of Sports Science of the State General Administration of Sport and the National Meteorological Center applied for the Chinese delegation to prepare for the 2024 Paris Olympic Games meteorological information research and application project to prepare for the Paris Olympic Games. To make meteorological service guarantee play a greater role, accurate forecasting must be demand-oriented.
"We conducted research according to the needs and made a detailed meteorological support plan. In terms of product types, different forecast schemes are given for outdoor key gold medal winning projects and other projects, detailed to the forecast from time to time and which meteorological elements; In time, the forecast includes short -, medium - and long-term forecast; In terms of space, including Paris and the surrounding area." National meteorological center weather forecast room technical chief Chen Yun introduction.
Although the Beijing Winter Olympics has achieved "minute level, 100 meter level" forecasting capabilities, but such accurate forecasting directly moved to Paris, there are still big challenges, need to be optimized according to local weather and climate characteristics.The weather and climate characteristics of France are different from those of our country. Guan Yue, chief forecaster of the Global Meteorological Room of the National Meteorological Center, introduced that Paris, France, has a temperate Marine climate, similar to the latitude of Harbin in China, and is relatively cool in summer. Its proximity to the ocean makes Paris less susceptible to temperature differences.Workers prepare the venue for the Paris Olympic Beach Volleyball competition at the Eiffel Tower Stadium in Paris, capital of China, July 25, 2019In order to make the Chinese sports delegation better adapt to the local weather, the National Meteorological Center released the first weather trend forecast during the Paris Olympic Games on June 26. On July 15, more than 10 days before the Paris Olympic Games were held, the National Meteorological Center issued the second phase of the Paris Olympic Games medium-term weather forecast. "During the Paris Olympics, there will be no extreme heat, rain or typhoons." Guan Yue said.Making such predictions is not easy. The weather room of the National Meteorological Center collects historical data, combs and analyzes a large amount of data, and understands the local climatic conditions. At the same time, the future weather is judged by the changing trend of atmospheric circulation situation. The lack of global meteorological element monitoring data is a "roadblock" for global forecasting.At the Paris Olympic stadium, staff of the Chinese sports delegation can be seen holding weather monitoring instruments. In order to obtain more precise monitoring data, the National Meteorological Center uses hand-held mobile observation equipment to monitor meteorological data in real time through the staff of the Chinese sports delegation. "Before going to Paris, we communicated with the relevant personnel of the Chinese sports delegation, and through the real-time monitoring of hand-held devices by the delegation staff, more precise meteorological data can be obtained and the forecast conclusions can be better supported." Li Xiaolan introduced. In addition, multi-source satellite image products also provide data for the forecast."We continue to improve the level of service refinement, in time, space, elements and other aspects of the forecast more accurate, increase the frequency of service." National Meteorological Center global meteorological room Meng Qingtao said. In the early stage, the China Meteorological Administration produced a booklet on the climate background of Paris, which not only included the introduction of weather and climate, but also included the analysis of sports and meteorological factors.Sports are closely related to weather. The meteorological department will provide more targeted and refined meteorological services for the Paris Olympic Games on the basis of the meteorological service support for the Pyeongchang Winter Olympics and the Tokyo Olympic Games.
