What is the knowledge about the 2022 Winter Olympics?
Looking back on the 2008 Olympic Games, it seems like yesterday. Time flies for several years. With the song "You and I, heart to heart, live in the global village", people all over the world are about to travel, and once again "travel thousands of miles for their dreams and meet in Beijing". In 2022, the Beijing Winter Olympics is about to open.

When we hosted the 2008 Beijing Olympic Games, real-time weather tracking made the rear guarantee for the smooth hosting of the Olympic Games, and colorful clouds and rains reduced the audience's amazement. More people are also looking forward to whether this Winter Olympics will be more exciting.

All the events of the Winter Olympics are related to winter, and the competition is held on ice and snow, so there are requirements for the temperature of the host city. The snowfall in February should be more than 30 cm, the average temperature should be lower than 0℃, and the extreme temperature should not be lower than-0/7℃. Too low or too high a temperature can easily affect the level of athletes. During this period, all kinds of weather may happen, and relevant meteorological monitoring equipment and meteorologists are extremely important.

The importance of meteorology

If there is extremely bad weather that hinders the competition and the manpower cannot be changed, the competition will still be temporarily postponed. It takes two years from bidding for the Olympic Games to formal confirmation. Air pollution index, weather changes and the adequacy of venues are all factors that affect the success of the Olympic bid.

There are *** 14 events in Beijing Winter Olympics. In these projects, some are carried out on snow and some on ice. However, whether it is on the snowy mountain or on the ice, the requirements for meteorological conditions and venues are higher, and the snow projects are all outdoors, and there are more uncontrollable factors. Sledding is thrilling, and the highest speed can reach 145 km/h during the competition.

In skiing competition, ski jumping is more affected by the weather, which requires an instantaneous wind speed of 3 meters per second, no crosswind, 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 sports meeting can be held normally and whether the athletes can play their normal level. In addition, during the competition, the referee will judge the timing according to the temperature, wind speed and wind direction. Therefore, it is very important to do meteorological monitoring well.

Monitoring element

It is difficult for ordinary weather stations to meet the monitoring requirements of various elements. For example, there are too many monitoring elements in special scenes, and multiple sensors of automatic weather stations need to be used together. Wind speed and direction, air temperature and humidity, noise, air quality, air pressure, illumination, rain and snow, ultraviolet rays, total radiation, carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, oxygen and carbon dioxide, etc. Monitor the meteorological environment in real time to protect the Olympic athletes.

Meteorological monitoring is important, and the site is equally important. The opening and closing ceremonies were still held in the Bird's Nest, and the Water Cube was renamed ice cube, because it was an ice competition venue. Of course, other competitions also have their own venues. The opening time of this Winter Olympics is on the fourth day of the Lunar New Year, so even people who go to work can watch the opening ceremony at home and look forward to it.

finally

Today, weather stations are no longer exclusive to weather stations. Large agricultural planting bases, small farms, campuses, scenic spots, parks, ecological parks, highways, etc. all have their presence. Different weather stations can be used to monitor environmental factors in different scenarios, especially in places where bad weather often occurs.
