Storms in 'atmospheric rivers' slow Arctic ice recovery

Sea ice loss in the Arctic could be exacerbated by violent storms that can move massive amounts of water as steam. Known as " But atmospheric rivers seem to be interfering with this, writes IFL Science..

“The shrinking of Arctic sea ice is one of the clearest indications of global warming in the past few decades.. Even though temperatures in the Arctic are well below freezing, winter sea ice reduction is still very large.. And our study shows that atmospheric rivers are one factor explaining why,” said Pengfei Zhang, lead author of the new study, from the University of Pennsylvania..

An atmospheric river is a thin, unstable column of condensed water vapor from the tropics, high in the atmosphere.. When the "

In 2021, scientists discovered that such " They form when atmospheric rivers separate and slow down to form a "

In a new study, scientists have combined satellite observations with climate modeling to find out how atmospheric rivers affect the Arctic during the glaciation season.. It turned out that the appearance of an atmospheric river affected the sea ice in this region.. He begins to retreat and continued to do so for the next 10 days..

This discovery is even more worrying as atmospheric rivers have become more frequent in recent years..

“When this moisture transfer occurs in the Arctic, the effect is not only the amount of rain or snow that falls from it, but also the powerful effect of ice melting..

This is significant as Arctic sea ice has been rapidly shrinking over the past few decades, with many undesirable effects such as Arctic warming, erosion of Arctic coasts, disruption of global weather patterns, and destruction of Arctic communities and ecosystems,” said Mingfang, co-author of the study..

Earlier, scientists said that the melting of glaciers could cause a new pandemic. Viruses and bacteria could be released from ice that is melting due to global warming.
