Climate Change Could Open Up “Rivers in The Sky” Over East Asia

Climate Change Could Open Up 'Rivers in The Sky' Over East Asia


We know the climate crisis is already here Having a profound impact on global weather systems, altering temperatures, rainfall, wind patterns, and more – and a new study predicts likely deluges over the mountainous parts of East Asia in the future.


The rain will pour. Atmospheric riversScientists predict that it will happen. Scientists predict that these narrow corridors of concentrated moisture could quickly cause flooding if they hit a barrier like a mountain range. This can release large amounts of water in a very short time.

The researchers’ models predict that East Asia’s rainfall events will become more frequent and more severe as the planet heats up. More water will be transported through air and more precipitation will land on ground.

“We find that both the atmospheric-related watervapor transport and rainfall intensify over South and West slopes of mountains over East Asia in warmer climates,” the researchers wrote in their paper. Publication of paper.

“Global warming will cause unprecedented rainfall in East Asia by means of atmospheric rivers.”

Atmospheric Rivers generally pick up moisture from warmer regions and deposit it in colder areas. Their movements are controlled by changes in wind and temperature – just the sort of changes that Climate ChangeYou can make a difference.

According to the study, rainfall levels could break records in regions like Japan, Taiwan, Northeast China, and the Korean Peninsula. The southwestern slopes will receive the majority of the rain. Japanese Alps.


To arrive at their conclusions, scientists ran simulations using meteorological data from 1951 through 2010, modeling that data up until 2090, and assuming an increasing temperature in accordance with more extreme scenarios of climate changes.

“We used high-resolution global atmosphere circulation model simulations, as well as regional temperature model downscaling simulators.” says environmental scientist Yoichi Kamae from the University of Tsukuba in Japan.

There have been many. previous research into these atmospheric rivers, but it’s still not fully clear how these bands of moisture will change as the climate does – especially as their behavior is determined by topological features as well as the movements of warmer and cooler air.

Some regions will see an increase in rainfall as a positive, while others could see severe weather conditions that could lead to flooding, which could be dangerous and life-threatening. This is the latest link between climate changes and flooding. An increasing numberExtreme weather events.

Researchers believe that the modeling could be applied to other areas where there might be atmospheric rivers. Although there is still a lot to be determined, it seems likely from this. Other studiesCertain parts of the world will see more rainfall over the next decade.

“Our findings are likely to also apply to other regions of mid-latitudes in which interactions between atmospheric river and steep mountains play an important role in precipitation,” says Kamae.

“These areas may also experience more severe and frequent extreme precipitation as the climate warms.”

The research has been published in Geophysical Research Letters.
