What is the geographical knowledge contained in the Winter Olympics?

The geographical knowledge included in the Winter Olympics is as follows:

1. The venue of the Winter Olympics is not as far north as possible, but as cold as possible. Therefore, almost all the host cities of the previous Winter Olympics are located between 30 degrees and 60 degrees north latitude, and the holding time is generally in February. -17℃- 10℃ is the most ideal temperature for hosting the Winter Olympics.

2. Meteorological conditions have an important influence on hosting the Winter Olympics. Not only is it a high-profile opening ceremony, but the requirements of various meteorological elements in winter events are even more demanding.

3. Considering the uncertainty of natural weather process, especially snowfall, and the strict requirements of snow sports on the venue, international events, especially the Winter Olympics, generally use funa to lay snow trails.

4. In the scoring process of ski jumping events, "wind speed score" occupies one of them, and athletes will lose points when they encounter headwinds, which is beneficial to flying; In case of adverse flight with downwind, extra points will be added to achieve balance. Other scoring criteria include "distance score", "attitude score" and "departure score".

There is a steep slope of 35 degrees on the runway of National Ski Platform Center. In order to prevent the sprayed snow from slipping, the artificial snow has to be repeatedly crushed by a snow press weighing about six tons, so that the snow can gradually become dense and become gorgeous ice-like snow.
