What are the conditions for hosting the Winter Olympics?

The conditions for holding the Winter Olympics are: first, the average temperature in February is below 0 degrees Celsius, and second, the snowfall in February is greater than 30 centimeters.

Cities with a probability of less than 75% for either of the two indicators will not have the right to apply to host the Winter Olympics. Many European countries, covered and radiated by the relatively cold Alps, have produced one-third of the world's Winter Olympic gold medals this century.

The Scandinavian mountains in Northern Europe contributed 17% of the world’s Winter Olympic gold medals. Almost all of the 19 cities in the world that have hosted the Winter Olympics are located in the mid-to-high latitudes of the Northern Hemisphere.

Artificial snowmaking in the Winter Olympics:

The snow in ski competitions is generally artificial snowmaking, and the general snow temperature is <0℃. The key to freestyle aerial skills is the wind, which requires an average wind speed of less than 3 meters/second within 1 minute during the competition period; Alpine skiing and freestyle competitions require visibility, which requires visibility >2 kilometers and an average wind speed of 5 minutes <10 meters/second. ; Biathlon and snowboarding have temperature requirements, which require the temperature to be ≥-18°C and the average wind speed in 1 minute to be <10 meters/second.

Cross-country skiing requires a temperature > -20°C and a 5-minute average wind speed <10 meters/second; ski jumping requires extremely high instantaneous wind speed, requiring an instantaneous wind speed <3 meters/second, no cross wind, and no headwind. It is more conducive to competition if the temperature is >-25℃.

When there is snowfall during the competition, it is easy to affect the competition. When there is heavy snow, heavy fog (visibility <2 kilometers), strong wind (wind speed >10 meters/second), strong warming (snow temperature >0℃) When the weather affects the weather, games are often temporarily suspended, the schedule is adjusted or even canceled.
