Ukrainian scientists at the Akademik Vernadsky station showed footage of "white nights" in the Antarctic. It is late spring and a long day in the It is late spring and a very long day in the area of the station. This is reported by the National Antarctic Science Center, reports UNN.
It is noted that in Antarctica, daylight hours are now 19 hours and 32 minutes, and its duration is increasing.
According to scientists, the longest day at Vernadsky will be on December 21, the day of the summer solstice in the Southern Hemisphere. It will will last 22 hours 24 minutes and 42 seconds (December 22 will be only 1 seconds shorter). Instead of night, it will be twilight for 1.5 hours.
Since our station is located north of the Arctic Circle, the phenomenon of the Circle, the phenomenon of the polar day - the period when the sun does not go below the horizon for more than day, is not observed here. For comparison, at the South Pole, the duration of the at the South Pole, the duration of the polar day is as long as 184 days,
They also told how the station staff reacts to such conditions. to such conditions.
Yes, we have to close the windows at night and celebrate the New Year and celebrate the New Year in the daylight. But after the Antarctic winter, the sun and bright daytime landscapes definitely improve your mood. The long daylight hours also add to the work of meteorologists, especially when the sky is clear. Then a special device - an aerosol solar photometer Microtops, scientists measure the concentration of aerosols in the atmosphere every hour in the atmosphere
This allows them to find out how the amount of of suspended particles in the atmosphere over a day, week, and month. This is important because such seemingly small aerosols play a huge role in shaping the weather and climate. Based on these measurements, climate models are then created not only for the polar regions, but also for the polar regions, but also for the entire Earth.

With good weather in summer, it is also a "hot time" for ozonometrists.
When the sky is clear, there are so many ozone measurements to be made, so much that the scientist hardly ever leaves the ozone office located in the attic in the attic. And if there are no clouds at sunset and at sunrise, the researcher will not have to sleep. Then the ozonomist conducts special Umker measurements, which make it possible to build a vertical profile of the ozone distribution in the atmosphere
Sunny weather and long days bring the polar explorers both joy but also a lot of work.
