What do you know about the 2022 Winter Olympics?

Looking back at the 2008 Olympics, it seems like it was yesterday. Time has flashed forward a few years. With the singing of "You and I, heart to heart, living together in the global village", people from all over the world are about to travel far and wide again. Traveling thousands of miles for dreams, meet in Beijing." In 2022, the Beijing Winter Olympics is about to begin.

When we held the 2008 Beijing Olympics, real-time weather tracking provided guarantee for the smooth hosting of the Olympics. The spectacular cloud elimination and rain reduction amazed the audience, and more people are also looking forward to it. Will the excitement of this Winter Olympics be even higher?

All the events of the Winter Olympics are related to winter, and the competitions are held on ice and snow, so there are requirements for the temperature of the host city. The snowfall in February needs to be greater than 30 cm, and the average temperature is below 0℃. , the extreme temperature cannot be lower than minus 17℃. Temperatures that are too low or too high can easily affect the performance of athletes. During this period, all kinds of weather may occur, and relevant meteorological monitoring equipment and meteorological experts are extremely important.

The importance of weather

If there is extremely bad weather that hinders the progress of the game and cannot be changed by manpower, the game will still be temporarily delayed. It takes two years from the application for the Olympics to the official confirmation. The air pollution index, weather changes, and the adequacy of the competition venues are all conditions that affect the success of the Olympic bid.

There are 14 events in the Beijing Winter Olympics. Among these events, some are conducted on snow and some on ice. However, whether it is on snowy mountains or ice, the required weather conditions The conditions and venues are more demanding, and the snow sports are all outdoors, with more uncontrollable factors. The sledding sport is thrilling. During the competition, the speed can reach up to 145 kilometers per hour.

In ski jumping competitions, ski jumping is more affected by the weather. It requires an instantaneous wind speed of three meters per second, no cross wind, headwind is conducive to the competition, and the temperature is higher than minus 25 degrees Celsius. Therefore, the importance of meteorological conditions to the Winter Olympics is clear at a glance. Precipitation, temperature, wind speed, wind direction, snowfall, and air are all factors that affect whether the event can proceed normally and whether athletes can perform at their normal level. Moreover, during the competition, the referee will also base on the temperature, wind speed, wind direction, etc. To determine the timing of issuing an order, weather monitoring is essential.

Monitoring elements

It is difficult for ordinary weather stations to meet the monitoring requirements of multiple elements. For example, when encountering special scenes, the meteorological requirements are more stringent and there are too many monitoring elements. A variety of sensors are used together in automatic weather stations. Wind speed and direction, air temperature and humidity, noise, air quality, atmospheric pressure, light, rain and snow, ultraviolet rays, total radiation, carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, oxygen, carbon dioxide, etc., provide real-time monitoring of the meteorological environment for Olympic athletes. They protect us.

Meteorological monitoring is important, and the venue is equally important. The opening and closing ceremonies are still held at the "Bird's Nest", and the "Water Cube" is also renamed the "Ice Cube" because it is an ice competition venue. Of course, other The competitions also have their own venues. The Winter Olympics will start on the fourth day of the Lunar New Year. Even people who work can watch the opening ceremony at home. We can look forward to it.

Finally

Nowadays, weather stations are no longer exclusive to weather stations. They are used in large agricultural planting bases, small farms, campuses, scenic spots, parks, ecological parks, highways, etc. You can see it, and different weather stations can be used in different scenarios to monitor environmental elements, especially in places where severe weather often occurs.
