Why don't most people in Antarctica choose April to September?

We say that there are extreme days and nights in the polar circles of the earth's poles. China is in the northern hemisphere, and the seasons in the northern hemisphere are just the opposite of those in the southern hemisphere. That is to say, when it is winter in the northern hemisphere and summer in the southern hemisphere, Antarctica is in a state of extreme daylight. When it is summer in the northern hemisphere and winter in the southern hemisphere, the Antarctic is in a state of extreme night. Therefore, in order to facilitate navigation, China generally chooses.

Secondly, Antarctica is one of the regions with the most frequent storm activities on earth. A cyclone is often generated every 30 minutes in the waters near Antarctica. There are often strong winds of 14 and huge waves as high as 15 to 20 meters in the sea area where cyclones pass. Therefore, it is only possible to deal with these storms in extreme daytime, and it will be quite dangerous in extreme nights.

Thirdly, there is a lot of ice in Antarctica, especially thick and hard ice layers such as continental ice and continental margin ice. If scientific investigation is carried out in the extreme night, it will have a great impact on the navigation and even safety of ships.
