Tonight's freestyle skiing men's aerial skills final
Qi Guangpu won the championship with a high score of 129 points
Plus the previous matches
The freestyle skiing aerial skills team ended with two golds and one silver
Review the game
Whether to notice this detail
Qi Guangpu won the championship and jumped up to the slip point alongside the Chinese flag
Xu Mengtao won the championship and jumped up to adjust the slippage point
Small flags planted at the departure point
In fact, there are many mysteries
It has a vital impact on the performance of athletes
In fact
This is a "struggle" with the wind
The Winter Olympic Observation Room invited Huang Fuxiang, a researcher at the China Meteorological Administration
Read it into detail with us
Freestyle skiing aerial skills are mostly in the mountains, and the wind conditions are changeable. In the whole process, the wind speed and wind direction will not only affect the athlete's movement completion, but also affect its safe landing, and if you are not careful, you may make mistakes and be injured. The speed of the introduction of freestyle skiing aerial skills, the gesture of action completion, etc. are very exquisite, which can be described as a missing millimeter and a thousand miles.
Therefore, athletes usually adjust the slippage point forward or backward in real time according to the coach's gestures before departure, according to the situation of the field wind, to obtain better introduction speed.
Xu Mengtao won the championship and jumped before the coach gesture
Many flags have been planted near the departure point for setting the slip point
On the field, we can often see the wind gauge appear in the lens.
In the past, coaches could only rely on handheld anemometers to know the wind conditions of the field, which was inaccurate. Coupled with the variable wind direction, the data obtained is often delayed.
After years of scientific and technological research, the National Meteorological Administration and the Institute of Spatial Information Innovation of the Chinese Academy of Sciences have jointly developed a wind measurement system to help athletes train, achieving high precision and "taking the pulse" of the wind.
The wind measurement system is innovatively designed with "three-point wind measurement" to achieve accurate measurement.
The wind measurement system converts the data into a "wind index" acting on the athlete in real time through a precise model.
The results of the wind measurement system are displayed on the mobile terminal to achieve data visualization.
Today, this intelligent wind measurement system has been used in the training and Winter Olympic test matches of more than a dozen national teams, including freestyle skiing aerial skills, to assist coaches in directing the game and decision-making on the spot. From perceiving the wind to seeing the wind, this wind measurement system is undoubtedly a huge progress.
Looking forward to the future, it will be more widely used in winter and even summer projects, becoming the "baton" of the arena.
