What is unpredictable weather?

In the Antarctic, the unpredictable weather also brings great difficulties to work.

Even in the Antarctic summer, storms often come suddenly, trapping people who are working in the field and making them unable to return to the camp for several days. Sometimes, when an expedition sees the weather is clear and sunny, it plans to go deep into the South Pole for investigation. However, just as they were about to start, a strong wind suddenly blew from the mainland, the sky suddenly darkened and there were snowstorms everywhere. As a result, the original inspection plan had to be suspended.

In the Antarctic, the frequent "milky white sky" is also a threat to researchers: the wind rolls up the ice crystals all over the sky, and the sunlight repeatedly reflects and refracts through the ice crystals, forming a solar halo phenomenon. Sometimes, ice crystals turn the sky white. You can't see the distant mountains, the horizon or even the people across the street. The marching players will lose their way; The tractor driver may overturn when driving the tractor; Planes flying in the air may be destroyed because they cannot be distinguished by ground objects whether they are ascending or descending. Therefore, Antarctic expedition members generally do not go out alone. When you go out, you should make all kinds of preparations for camping in the wild: bring food for a few days, a simple cold-proof tent, and you must also bring a radio transceiver in case of an accident.

Even if you don't go out and hide in the military camp, the weather in Antarctica makes people fidget. A snowstorm overnight can bury the whole camp in a sea of snow, and the gate is blocked. In order to observe outside, people have to mobilize all the snow sweepers and bulldozers to clean up, and sometimes they even have to be busy all day to clean up.
