Winter Olympics
Conduct joint weather consultations based on weather and events
In October of this year, the weather protection service in the Beijing area and the Yanqing competition area was launched, and the weather service team successively stationed in corresponding institutions and venues to carry out services.
In October and November, the two competition areas will host the "Meet in Beijing" series of winter sports events in the second half of 2021 test competitions and test activities.
In the meantime, the Beijing Meteorological Observatory added meetings on the weather situation of the competition area in the weather meeting every afternoon, and carried out joint weather consultations with the Central Meteorological Observatory and the weather service team in the competition area according to the weather conditions and event arrangements.
Winter Olympics outdoor projects are directly affected by weather conditions
Fu Jiaolan, the chief forecaster of the Central Meteorological Observatory, is responsible for weather protection services for the Beijing Shougang Ski Jump Project.
She believes that she became attached to the Winter Olympics because her previous research directions were consistent with the Winter Olympics.
During 2015 and 2016, Fu Gueran did research on winter snowfall and snow cover forecasts. The Winter Olympics include many outdoor projects, which are greatly affected by the weather. If they want to be held successfully, they have to pay attention to such winter disasters. The impact of the weather.
The Shougang Ski Jump, which is in charge of Fu Jiaolan, is the only competition venue located in Beijing in the snow project.
During the Winter Olympics, the ski jumping platform will host snowboard and freestyle ski jumping competitions.
The total length of the big jumping platform track structure is 164 meters, the starting area is 48 meters high, and the end area is -4 meters.
During the competition, the athletes slide down from a high place, take off through the big jumping platform, and perform various aerial movements such as somersaults and turns.
Fu Jiaolan said: "Athletes are tumbling in the air, so the accuracy requirements for wind forecasts are very high." Slightly violent gusts may have an impact on skiers' flying posture in the air and landing safety.
Forecasters help overcome the limitations of natural conditions
In the winter of 2020, Fu Gueran was training in the Yanqing competition area and was preparing for the test competition of the alpine skiing event.
The National Alpine Ski Center track, with a vertical drop of about 900 meters and a slope of about 3,000 meters, is recognized as one of the most difficult venues in the world. It is extremely challenging for participating athletes and requires strict weather forecast services during the event.
According to Fu Jiaolan, the alpine skiing competition requires the use of a cable car to quickly help the athletes to reach the top of the mountain from the bottom of the mountain. If the wind is too strong, it will be very unfavorable to the operation of the cable car.
She and other forecasters stationed in the Yanqing competition area observed that during the period from January 17 to 19, there was a cold air process and the wind was relatively high, which is expected to be greater than 20 meters per second. The event organizer was originally scheduled for January. The competition will take place from the 16th to the 19th.
"This wind speed has a very large impact on the operation of the cable car, so it is not recommended to use the cable car. According to the forecast, as the cold air gradually passes through the border, the wind will gradually decrease on the 20th, below 20 meters per second, which has little effect on the competition. Event organization Fang adopted our forecast and adjusted the game process and decided to start the game again on the 20th. In the end, the game went smoothly."
What the forecasters do is to overcome the limitations of natural conditions and help athletes reach faster, higher, and stronger.
