What Is The Temperature In Antarctica - A meteorological station on Seymour Island in the Antarctic Peninsula registered a temperature of 69.3 degrees (20.75 Celsius) on February 9, according to Márcio Rocha Francelino, a professor at the Government University of Vicosa in Brazil.
The temperature was nearly 70 degrees higher than the 65-degree reading taken on February 6 at Esperanza Base on Antarctica's Trinity Peninsula. The World Meteorological Organization (WMO) is reviewing the readings to see if they could be the country's hottest on record.

The new data, seen by the Washington Post, comes from a 12-year-old research facility used primarily to monitor the permanently frozen layer of soil called permafrost. Francelino said that if the temperature in the area is flat and open, there is no problem.

Randall Cerveny, a meteorologist at Arizona State University who analyzes the situation for the WMO, previously called Esperanza reading "data will be available." On Thursday, he said the agency was also reviewing the new report, but cautioned about reading more.
He said many questions need to be answered before a reading of nearly 70 degrees is considered the hottest on record in the world's coldest country. "We will want to have a good look at the metadata of the station (how long it has been there, how good the observations are, what type of pump is used, when it was last measured, etc.), he said. email. "All these factors are important to determine the accuracy of the survey."
"It will be some time before we at the WMO Meteorological and Meteorological Archives can provide a benchmark for this analysis," said Cerveny, noting the difficulties associated with the data. Evidence from distant places, especially those that are not eternal. .
According to Francelino, the weather station in question is one of 26 stations operated by other scientists around Antarctica.

The unusually warm reading was first reported by The Guardian, which revealed that it was a document. However, Jefferson C. Simões, a glaciologist at the Federal University of Rio Grande do Sul and vice president of the Antarctic Research Council, who also confirmed the reading, said he did not believe the measure would meet the WMO's criteria for a reading. legal documents.
However, he said he considered it important to confirm the "heat" in the northern part of Antarctica last week. Both places are located in the region of Antarctica that is closest to South America, while the interior of the continent reaches its coldest point.

"This is an important step, but it will not be recognized by the WMO, because it has not been measured at [a] weather station with long data," he said in an email. He mentioned that the height of the thermometer is why the WMO can reduce it. Most weather stations have a two-meter height reading, and this reading is taken at 1½ meters. The temperature can be higher if it is placed closer to the ground.

According to Cerveny, WMO guidelines allow them to accept 1½ meters of temperature data, so short data is a bigger problem.
According to Francelino, the Seymour Island station registered a temperature of 61.5 degrees (16.4 Celsius) on February 6, while Argentina's Esperanza Station reached 65 degrees (18.3 Celsius).
He called the results "remarkable" in their own right. Then, on February 9, the Brazilian Antarctic Station on King George Island recorded a temperature of 66.7 degrees (19.38 Celsius) at the same time as the permafrost research area reached close to 70 degrees.
"I don't know if the Esperanza station in Brazil is registered or compliant with the WMO standards, but just to record the results it should be studied better," said Francelino. Unusually small weather has a short duration of two weeks. On February 10, for example, it reached 61 degrees for high.

The Arctic may have crossed the threshold, releasing billions of tonnes of carbon into the atmosphere, in long-feared climate change.
Computer models say the size of the Antarctic Peninsula will be between 20 and 40 degrees above normal between February 7 and February 9, because of the patch There is a lot of violence around.
But the average temperature on the first day of February at the Seymour Island research site was more than 39.2 degrees (3.9 Celsius).
"In three places, over a period of 13 years, the temperature of the permafrost has been slightly different, remaining stable in general and in some showing a little warmer. Only one shows a coolness," he said.

This is compared to rapid warming starting in the vast permafrost of the Arctic, whose melting could be a major climate change that will help accelerate global warming.
The Antarctic Peninsula is one of the warmest places in the world. Most of the glaciers in the region are retreating rapidly. According to a 2018 study, the ice sheet is collapsing and the speed of ice moving into the sea on the Antarctic Peninsula caused an increase of 25 billion metric tons of ice per year from the area between 1992 and 2017.
This area most famously saw the rapid breakup of two large ice shelves: the Larsen B Ice Shelf in 2002 and the Wilkins Ice Shelf in 2008. The rapid warming here has led to more observations, as scientists worry about ice loss. changed to include all countries.
Correction: This story has been amended to indicate that Brazil's Antarctic base is on King George Island, not Seymour Island as noted. However, the hottest record was recorded on Seymour Island.
Antarctica's Climate: The Key Factors
Maybe news is a story. Follow the team of reporters and journalists who write about the news. If you haven't been to Antarctica yet, you'll be curious to see what awaits you. It may seem landlocked in the winter, but with 1,860 miles from the South Pole and the northern part of the Antarctic Peninsula, it is not surprising that there are climate changes throughout the country. When it comes to travel plans, the devil is in the details, so here are some important tips for Antarctic weather at different times of the year.
Unlike the four seasons that most of us live in, Free country is only summer and winter. The existence of the Antarctic winter, between April and October, is only for scientists. Argument is a rule that will not be forgotten because the darkness can last for weeks, there are no visitors and the average temperature is -45 ° C (-50 ° F) - this is more than twice as cold as the refrigerator in the kitchen. .
Summer in Antarctica is a different story. With the sea ice receding, the Free State has access to frozen ice for cruise ships from November, and the season runs until the end of March. That's five months of adventure and exploration, and you can expect plenty of weather, wildlife and ice during that time.
If you travel in November, you will be one of the first to visit Antarctica after it is locked in the dark winter, and the dream will be defeated. You can have the opportunity to walk on ice rapids - frozen ice that stretches from the coast - and witness the landscape draped in white powder, perfect for snowshoeing.

The weather in Antarctica in November varies depending on where you live on the continent, and will be less predictable than in winter. The average temperature in Antarctica in November is -6°C (21°F) on the north coast - plus the harsher land climate. Photographers should look out for beautiful golden sunsets and rare noctilucent clouds created by ice crystals that appear as ghostly silver strands in the sky.
The arrival of December makes the days longer, with 24 hours of daylight giving you more time to explore. The average temperature in Antarctica in December is 0°C (32°F) on the north coast. This relative warmth is melting the ice and restoring wildlife in Antarctica, so you can expect to see the first baby penguins and humpback whales.
The weather in Antarctica in December is usually defined by blue skies and sunny days, but you should not rule out the occasional storm at the bottom of the world, so make sure you have plenty of warm clothes. You can spend the festive season in Antarctica surrounded by ice and snow for a free Christmas.
The weather in Antarctica in January is more stable as it is the peak of summer, making it one of the most popular months to visit. The temperature in Antarctica in January is 6°C (43°F). Tourists can expect to be entertained as the penguins welcome their chicks into their rookeries. Daylight hours begin to decrease in late January, although you can still expect them to be longer
