Arctic warms up faster due to radiation - study

21 november 2024

The researchers found out that from 2005 to 2022, the average winter temperature in the Eastern hemisphere of the Arctic increased by 5 degrees. Scientists have linked this phenomenon with long-wave radiation flows, the Russian Science Foundation reported on its Telegram channel.

Back in 2005, researchers found out that temperatures rose sharply in the Eastern hemisphere of the Arctic in winter. Along with it, the flow of long-wave radiation rose by 9% due to an increase in the concentration of water vapor in the Arctic air.

This data allows for a better understand of the phenomenon of Arctic warming faster than other regions of the world.

"An important conclusion is that radiation processes have a key impact on the winter climate in the Eastern hemisphere of the Arctic," the Russian Scientific Foundation reported.

The results obtained will help scientists refine climate models and forecasts, sever-press.ru notes.
