The reason for sudden temperature fluctuations in high latitudes may be changes in the parameters of the earth's atmosphere, lasting for more than two weeks. This is the conclusion reached by the researchers of St. Petersburg State University.
Physicists used a mathematical model to study the effect of planetary waves with periods from 3 to 16 days on the large–scale circulation of the atmosphere - these are global fluctuations in parameters such as pressure, density, temperature, wind speed. The duration of "tides" and "ebbs" can reach 30 days, RIA Novosti writes with reference to the Ministry of Science and Higher Education.
Experiments have shown that waves may well cause disturbances in the stratosphere, which lead to extreme warming and cooling in the Arctic zone and temperate latitudes.
Earlier, scientists suggested that the acceleration of the water cycle in the Arctic could affect the entire ecosystem. Russian geophysicists believe that the Arctic could have warmed up sharply due to powerful earthquakes. The ice in the Arctic has become thinner, and their durability is shorter.
ALROSA presented the interim results of its corporate program "Territory of Well-Being"—a large-scale project that helps employees of Yakutia's diamond mining companies develop a mindful and healthy lifestyle.
Currently, the Russian icebreaking fleet has 43 icebreakers, including 8 nuclear-powered ships and by 2030 14 more icebreakers and 9 ice-class tankers will be built, said Deputy Minister of Transport Konstantin Pashkov.
Russia’s deputy prime minister Yuri Trutnev and governor of the Murmansk Region Andrey Chibis proposed declaring 2027 the Year of the Arctic in Russia.
The development of the Northern Sea Route (NSR) is impossible without the modernization of the main cities located in the Arctic, said Dmitry Pristanskov, State Secretary and Vice President of Norilsk Nickel.
The polar branch of Norilsk Nickel conducted comprehensive exercises to localize and eliminate the accident at the water transport operation site on the Norilsk River.
The Northern Sea Route (NSR) will host the first container transit voyage from a Chinese port to European ports, said Vladimir Panov, Deputy Chairman of the State Commission for Arctic Development.
