Antarctica was tropical in ancient times. Warmest month in Antarctica

Author Lisa Sokolova asked a question in the section Climate, Weather, Time Zones

what time is it in Antarctica and got the best answer

Answer from Helga[guru]
Antarctica is a place where everything looks the same. Everything seems the same, but not the time. On this continent, time zones intersect and overlap.
Most Antarctic stations are set to the time of the state to which the station belongs. Since stations are located chaotically, sometimes surprising paradoxes arise. It is enough to drive a couple of kilometers to the neighboring Antarctic station to get back a few hours. A map of "time zones" in Antarctica is attached. It's funny that the time at Scott (NZ) and Rothera (UK) stations differs by as much as fifteen hours. Although the stations are not located at different ends globe.
Time zones in Antarctica

At the North and South Poles, the meridians converge at one point, and therefore there the concept of time zones, and at the same time local time, loses its meaning. It is believed that time at the poles corresponds to universal time, but at the Amundsen-Scott station ( South Pole) New Zealand time is in effect, not world time.

Hello! Here is a selection of topics with answers to your question: what time is it in Antarctica?

In January 1820, a Russian expedition led by Thaddeus Bellingshausen and Mikhail Lazarev discovered Antarctica, the existence of which had previously only been speculated. Today we have collected for you interesting and little known facts about the most remote southern continent - the highest, driest, windiest, sparsely populated and coldest place on earth.

1. At one time, it was impossible to work in Antarctica for those who had not had their wisdom teeth and appendix removed. Due to the fact that surgical operations were not performed at Antarctic stations, to work here it was necessary to first part with these parts of the body, even if they were completely healthy.

3. Like many countries, Antarctica has its own Internet domain - .aq

4. 53 million years ago it was so warm in Antarctica that palm trees grew on its shores, and the air temperature rose above 20 degrees Celsius.

5. In December 2013, Metallica gave a concert in Antarctica, thus becoming the first band in the world to perform on all continents. In order not to disturb the local fauna, the concert was held under a special protective dome, and the audience listened to the music through headphones.

6. From 1960 to 1972, the first US-owned settlement and research center operated at McMurdo Station. nuclear power plant in Antarctica.

7. Antarctica has its own fire station. It belongs to the McMurdo station, and it employs real professional firefighters.

8. Despite extreme conditions, 1,150 species of fungi have been discovered in Antarctica. They adapt well to extremely low temperatures and extended periods of freezing and thawing.

9. Technically, all 24 time zones are present in Antarctica, since their boundaries converge at one point at both poles.

10. There are no polar bears in Antarctica. To see them you have to go to North Pole or, for example, to Canada.

11. There is a bar in Antarctica - the southernmost bar on the planet. And it is located at the Akademik Vernadsky station, which belongs to Ukraine.

12. Most low temperature ever recorded on earth - minus 89.2 degrees Celsius - was recorded in Antarctica on Russian station"Vostok" July 21, 1983.

15. The average ice thickness of Antarctica is 1.6 km. Antarctica contains approximately 70% of the world's reserves fresh water on the ground.

16. The Transantarctic Mountains run across the entire continent and divide it into western and eastern parts. This ridge is one of the longest in the world - its length is 3,500 km.

17. The existence of the continent of Antarctica was unknown until its discovery in 1820. Before this, it was assumed that it was just a group of islands.

18. On December 14, 1911, Norwegian explorer Roald Amundsen became the first person to reach the South Pole and plant his nation's flag there. He also became the first person to visit both geographic poles of the planet.

19. As a result of secret negotiations, on December 1, 1959, 12 countries concluded the Antarctic Treaty, providing for the demilitarization of the Antarctic area and its use for exclusively peaceful purposes. Today, more than 50 countries are parties to the Treaty.

20. On January 7, 1978, Argentinean Emilio Marcos Palma was born - the first person in history to be born in Antarctica. It is believed that this event was a planned action by the Argentine government, which specifically sent a pregnant woman to the Esperanza station in order to subsequently claim rights to part of the territory of Antarctica.

Perhaps there is no place in the world more mysterious than Antarctica. The vast expanses of ice could tell a lot about what the Earth was like millions of years ago. But nature is in no hurry to reveal its secrets, and people return here again and again, fighting the cold and blizzard.

Antarctica is frozen heart Antarctica: on an area of ​​13 million 661 thousand km 2 there are 30 million km 3 of ice! The continent is crossed by the geographic South Pole, the Pole of Cold (-89.2 °C - the lowest temperature), the Pole of Inaccessibility, conquered by a Soviet expedition in 1958, and the South Geomagnetic Pole.

The territory of the mainland does not belong to any country. In Antarctica, you cannot develop mineral resources or carry out production work - only scientific activity, therefore, in addition to seals and penguins, the mainland is inhabited by scientists from different countries. Only well-trained people, strong in spirit and body, live and work here. The reason for this is extreme conditions and harsh climate.

Features of the climate of Antarctica

The warmest time on the mainland occurs from November to February - this is spring and summer in Southern Hemisphere. On the coast, the air can warm up to 0°C, and near the cold pole the temperature rises to -30°C.

Summer in Antarctica is so sunny that you should never forget about sunglasses - you can seriously damage your eyesight. And you can’t do without lipstick either - without it, your lips instantly crack, and it’s impossible to eat or speak. Why then is it so cold and the glaciers are not melting? Almost 90% of solar energy is reflected from ice and snow cover, and if we take into account that the continent receives solar heat mainly in the summer, it turns out that during the year Antarctica loses more heat than it gains.

The lowest temperature is from March to October, autumn and winter in Antarctica, when the thermometer drops to -75°C. This is a period of severe storms, planes do not fly to the mainland, and polar explorers find themselves cut off from the rest of the world for 8 long months.

Polar day and polar night in the Southern Hemisphere

In Antarctica, as well as in the Northern Hemisphere, there is a polar night and a polar day, which last around the clock. If we rely only on astronomical calculations, then December 22, on the day summer solstice In the Southern Hemisphere, the sun should only be halfway below the horizon at midnight and then rise again. And June 22, on the day winter solstice- only half appear on the horizon at noon, and then disappear. But there is astronomical refraction - optical phenomenon associated with the refraction of light rays. Thanks to refraction, we see luminaries before they appear above the horizon, and for some time after they set. Therefore, the usual change of day and night occurs only in spring and autumn. In winter there is a polar night, and in summer there is a polar day.

Nature of Antarctica

Peculiar business card Antarctica - penguin. Several species of these funny birds live here: on the continental coast - emperor, king, gentoo, and Adelie penguins. And on the Antarctic and subantarctic islands live the crested, arctic, and golden-haired penguins.

There are other birds: petrels (Antarctic, snowy, silver-gray), skuas,

Antarctica is the habitat of several species of seals: Weddell seal, Ross seal, crabeater seal, southern sea ​​Elephant, leopard seal, Kerguelen fur seal.

Whales live here: blue whale, flat-faced bottlenose, sperm whale, killer whales, sei whale, southern minke whale.

It's hard to imagine, but even here, on icy continent, there is vegetation. Lichens, cereals and clove herbs, whose height does not exceed 1 cm, and some types of moss, hide in the crevices of rocks.

Polar stations of Antarctica

Most stations are located in coastal zone continent, and only three of them are inland. These are the American Amundsen-Scott base, the French-Italian Concordia base and the Russian Vostok base.

Associated with the discovery of the “East” interesting story. When in the early 50s, at a meeting in Paris, questions about the development of Antarctica were decided, our delegation was given the task: to prove at all costs that Soviet Union there are enough resources to maintain the operation of the station at the very South Geographic Pole. But due to delays with passports and visas, our delegate was late for the start of the meeting, and this place had already been promised to the Americans. We got the South Geomagnetic Pole and the Pole of Inaccessibility. In 1957, the South Geomagnetic Pole was founded scientific station"East". And after 50 years, scientists managed to get a water sample underground lake, located, as it turned out, right under the station! The fifth largest volume of fresh water, hidden under ice at a depth of almost 4000 m, Lake Vostok sheds light on the origins of the Earth and life on Earth. This is incredible luck!

There are a total of 5 located in Antarctica Russian bases, working all year round: “Bellingshausen”, “Mirny”, “Vostok”, “Progress”, “Novolazarevskaya”. Scientists study the atmosphere, weather, ice, movement earth's crust. All bases have the most comfortable conditions: in addition to everything necessary for work, there are rest rooms, Gym, billiards, library. IP-telephony and Internet access have been established, channel 1 is broadcast.

The closest neighbors of the scientists from the Novolazarevskaya base are specialists from India. The name of their base - "Maitri" - means "friendship" and best describes the relationship between the polar explorers. By the way, a warm, friendly atmosphere has always been here. Even during Cold War scientists conducted joint research and used each other’s work.

Except traditional holidays the bases mark the beginning and end of each expedition. At the gala dinner, a symbolic handover of the key to the station takes place. Despite see you soon with relatives, scientists leaving the station involuntarily envy those who remain for the winter - Antarctica does not let go. Cold, blizzardy, but so beautiful.

Polar scientists and weather forecasters jokingly call Antarctica the “weather kitchen” for the entire planet. Experts know exactly when conditions are more or less favorable for traveling to the vicinity of Yuzhny geographic pole. Ordinary people are often lost in conjecture: “Which is the most warm month? Are there above-zero temperatures in Antarctica?” It’s not easy to figure out what’s going on in the “weather kitchen”; everything is different here, not like on other continents.

The white continent becomes more accessible

Until the 20s of the 19th century, scientists and travelers argued about the existence of land near the South Pole. Many believed famous navigator J. Cook, who declared the inaccessibility of the territory south of 71° south. w. The Russian expedition to Antarctica on the ships “Vostok” and “Mirny” on January 20, 1820 discovered unknown lands, despite many insurmountable obstacles. After 120 years, the first excursions to Antarctic waters began, and it took another 50 years to develop a new tourist destination.

Hundreds of adventurers travel to the white continent every year. Expeditions and tours are conducted during the most favorable period of the year in the Southern Hemisphere. “What is the warmest month in Antarctica?” - the townsfolk ask in bewilderment. Of course, at school everyone was taught the climate of the southern continents, where our winter is summer. Many find it difficult to say exactly which month is best for a tour to the South Pole.

Antarctica and the Arctic - two opposites

Let's briefly look at geographic terminology. The land in the south owes its name to the Arctic. This word, denoting the northern polar latitudes of the Earth, is of Greek origin, given according to the position of Weather on for a long time remained a mystery, because the path for researchers of the 18th-19th centuries to the cherished point with the coordinate 90° N. w. blocked by the cold waters of the ocean, ice and snow.

The territory in the south, opposite the northern polar region, was called "Ant(i)arctic", the mainland - Antarctica. The South Pole is located almost in the center of the continent. Geographic coordinate this point is 90° S. w.

The southernmost and coldest continent

Harsh climate south of latitude 70°S. w. received the names “subantarctic” and “antarctic”. During the year, surface areas free from snow and ice on the coast and in oases warm up better. In winter, temperatures on the coast and in the northern part of the Antarctic Peninsula are comparable to arctic belt(from −10 to −40 °C). In the summer in Antarctica you can find many islands of land among the icy silence, where the thermometer rises above 0 ° C.

Features of the climate of Antarctica:

• Winter lasts from June to August, this is the coldest period.
• average temperature July is between -65° and -75°C.
• Summer begins in December and lasts until February.
• Temperatures in the continental part rise from −50 to −30 °C.
• The warmest month in Antarctica is January.
• The polar day lasts from September to March. The sun remains above the horizon, heating the surface more.
• The night lasts almost half a year, illuminated by bright flashes of the aurora.

Inland climate

Antarctica is a continent where regular weather observations began later than on inhabited continents. Special attention Forecasters over the last 50-60 years have used data obtained at stations on the mainland and coastal parts of the white continent. The coldest regions are the southeast, where average annual temperature is about −60 °C. Temperature maximum in the area of ​​the Vostok station is −13.6° C (December 16, 1957). Average monthly temperature from April to September - below −70 °C.

The weather at the South Pole is a little milder; this part of the continent is closer to the coast. Meteorological information at a point with coordinates 90° S. w. collected by employees American station“Amundsen-Scott”, named after the “Napoleon of the Polar Countries”, the Norwegian Roald Amundsen and another discoverer of the South Pole, an Englishman. The station was founded in 1956 at the South Pole and gradually “drifts” towards the coast. Antarctica has the shape of a dome, the glacier slowly slides from the center to the edges, where its pieces break under their own weight and fall into the ocean. In winter, in the area of ​​the Amundsen-Scott station, the thermometer shows −60 °C; in January it does not drop below −30 °C.

Weather on the coast of Antarctica

In summer, on the shores of the oceans and seas washing the most southern mainland, much warmer than in continental regions. Over the Antarctic Peninsula, the air warms up to +10 °C in December-February. The average January temperature is +1.5 °C. In winter in July, the average monthly temperature drops to −8° on the coast of the Antarctic Peninsula, to −35 °C in the area of ​​the edge of the Ross Glacier. One of the climatic anomalies of the continent is cold katabatic winds, the speed of which reaches 12-90 m/sec on the coast (hurricanes). Rains like heat, in Antarctica - a rare phenomenon. Mostly moisture enters the continent in the form of snow.

Antarctica is a “multipolar” continent

“Pole of Inaccessibility” is the name Russian polar explorers came up with for their station. The Soviet expedition to Antarctica carried out Scientific research beyond the 82nd parallel in the most difficult highland region of the mainland for movement.

On the mainland there is the “Pole of Cold” - this is the area of ​​​​the Vostok Antarctic research station, created in Soviet time. Here, the lowest air temperature in the entire history of meteorological observations was recorded using ground-based measuring equipment: -89.2 °C (1983).

Researchers from the United States, armed with satellite data, tried to challenge the “record” of the Russian station. The Americans reported in December 2013 that it was located in the area of ​​the Fuji Dome station, which belongs to Japan. The absolute minimum temperature for Antarctica was -91.2 °C, which was determined using a satellite.

Antarctica is the prototype of a “multipolar” world without borders and an arms race. The international legal regime was introduced here in 1961. The continent and the adjacent parts of the oceans do not belong to the states parties to the treaty and observer countries; they can only conduct scientific research.

What to do during the warmest month in Antarctica and the Arctic

Exploration of the North and South Poles, the white continent in the south and the ice of the Arctic has always been the lot of the brave and patient. Today there are many people on the planet who have visited Antarctica more than 100 times. Some conduct scientific research, others ensure transport accessibility, safety, and provide medical care.

More and more people are going beyond the Antarctic Circle in search of fantastic experiences. Tours to Antarctica at first glance seem pure water adventurism. In fact, all flights, sailings and excursions are prepared for top level. Polar scientists act as consultants, icebreakers and research vessels are used.

Peak "tourist season" in the polar regions

The high cost of a flight or sea cruise to the North and South Poles and the high costs of organizing expeditions do not stop modern adventurers. Let's paraphrase famous saying foreman from the film “Operation “Y” and other adventures of Shurik.” Now dozens of ships with tourists are “cruising the expanses” of the Arctic and Antarctic. The day is not far when there will be many more of them. " High season"at the South Pole begins in December and lasts until January. At this time, the hemisphere is better illuminated by the Sun, and the height of summer begins.

The weather at the North Pole is warmer than at the South Pole. The climate also depends on the low angle of the Sun above the horizon and the strong reflectivity of snow and ice. Temperatures in winter in December-February and summer in June-August are much higher than in Antarctica. The average winter temperature at the North Pole is −30 °C. Thaws (−26 °C) and cold snaps (−43 °C) often occur. The average temperature in summer is about 0°C.

Are there any “white spots” left in Antarctica?

The Age of the Greats geographical discoveries completed in the 20s of the last century by S. V. Obruchev, the son of the scientist, traveler and writer V. A. Obruchev (“Geology of Siberia”, “Sannikov Land”). Sergey Obruchev explored the last “white spots” in Eastern Siberia and in Chukotka. By that time, a significant part of Antarctica was still little studied.

Gradually, researchers found out the thickness of the glacier and the features of the subglacial relief, and collected detailed meteorological information. Many “white spots” on the sixth continent are closed, but the south polar continent still keeps many mysteries and secrets. For avid travelers, a warm month in Antarctica means new experiences, an opportunity to see rare representatives of the animal world and take unique photographs.

Are expeditions to the Antarctic Circle dangerous?

There are reports of any unforeseen situations with tourists in Antarctica, but they are rare. For example, in November 2009, the Russian ship Kapitan Khlebnikov became stuck in the ice off the coast of the Antarctic Peninsula. Among its passengers were tourists and a film crew from the UK. The reason for the stop was weather, but as soon as the tide began to ebb, the ship managed to free itself from the “white captivity.” A Russian icebreaker with English tourists and television crews on board was cruising in the area (West Antarctica).

A map of the mainland and the Antarctic Peninsula gives an idea of ​​the location of the sea, but only experienced pilots can navigate ships between the icebergs. In December 2013, drifting ice stopped the Russian ship Akademik Shokalsky. Passengers were evacuated aboard the Australian icebreaker in early January 2014.

Tour to Antarctica - a high dose of adrenaline is guaranteed

According to Antarctic researchers, the continent is suitable for organizing cruises, dog sledding and other types of travel. active rest. Story sea ​​cruises in Antarctica for more than 90 years. In 1920, enterprising ship owners began taking on board the first tourists who wanted to see the white continent with their own eyes. The cost of modern cruises and other types of travel to the shores of Antarctica and the South Pole ranges from $5,000 to $40,000. The price of the tour depends on many factors, not least the complexity of the route and excursion support.

The official version says that Antarctica was discovered during the Russian expedition of Bellingshausen and Lazarev in 1820. But already by end of the 19th century centuries, researchers doubted this fact and hypothesized that the discovery of the mainland occurred much earlier. The reason for this was the map compiled by the Turkish admiral Piri Reis...

Ancient subglacial lake discovered in Antarctica

Antarctica on an ancient map

When compiling the maps, Rice used manuscripts that survived the destruction of the Library of Alexandria by the Arabs. The map around which passions flared up dated back to 1513. Interestingly, it depicted the mountain ranges of Antarctica, which are now buried under thick ice and were recently discovered using seismic sounding.

It's interesting that Almost all ancient geographers were firmly convinced of the existence of a certain continent in the South. There was also legendary information about the land in the South dating back to the 15th century BC.

In 1897, the English steam brig Queen Elizabeth anchored in a bay off the Antarctic coast of Queen Maud Land. It should be noted that this year turned out to be abnormally hot throughout the globe. When the sailors climbed to a small plateau 10 miles from the coast, they saw that the ruins of unknown structures had thawed from under the multi-meter thickness of ice. Unfortunately, it turned out to be impossible to get inside, since the lower part of the structures was still under the ice...

Based on the sensational discovery, a special expedition was planned, which was to take place in 1899. But the Anglo-Boer War began, and with its beginning all plans were forgotten. And only in the second half of the 20th century, in 1977, research was continued thanks to new unexpected finds.

Mysterious golden hairs in Antarctica

At that time, experimental research was carried out in the ice basin of the Arctic and Antarctic Research Institute. An expedition arriving from Antarctica unloaded ice cores obtained by drilling a kilometer-long layer of ice above one of the subglacial Antarctic lakes. It has been suggested that this ice should not be used, much less melted, until it is determined that it does not contain pathogenic organisms.

And then they decided to involve biologists in the research. Samples were taken for analysis, which showed that one of the samples contained short gold wires the thickness of a human hair, as well as wood chips. Interestingly, the length of the metal hairs was 2 centimeters, and all the hairs found in different samples had the same length, straight ends, and almost no elasticity. During the experiment, they were squeezed with tweezers, and dents appeared on them.

These mysterious hairs did not dissolve in hydrochloric, sulfuric, nitric, or acetic acids, which is characteristic only of gold...

There is also evidence from Norwegian archaeologists dating back to the late 80s. They claim to have discovered Antarctic ice gold jewelry, dishes, masks and even unknown instruments. True, in scientific circles this discovery was “silenced”, since it went very much contrary to the generally accepted version of the history of the mainland...

Apparently, in ancient geological eras, Antarctica was different warm climate, an abundance of flora and fauna. Natural disaster, which changed conditions on the mainland, most likely destroyed the bridges connecting eastern Antarctica with Africa and South America. Evidence of climate change was found in layers 280-320 million years old.

Among them are fossil remains of plants and animals, including ichthyosaurs, which were heat-loving reptiles, and fern flora.
