We know that the climate crisis is already having a profound effect 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.
Scientists predict that atmospheric rivers will bring on the rain. When these narrow corridors of concentrated water hit a barrier such as a mountain range, they can cause flooding in a matter of minutes.
As the planet warms up, there will be more frequent and more severe rain events in East Asia. There will be more precipitation on the ground.
In a warmer climate, the atmospheric river-related water vapor transport and rainfall intensify over the southern and western slopes of mountains.
Extreme rain will come over East Asia under global warming.
The atmospheric rivers pick up precipitation from warmer areas and deposit it in the colder regions. Climate change can bring about changes in wind and temperature that control their movements.
The study states that the rainfall could reach record-breaking levels in regions such as Japan, Taiwan, northeastern China, and the Korean Peninsula. There will be rain on the southwestern slopes of the Japanese Alps.
To reach their conclusions, the scientists ran simulations based on meteorological data collected from 1951 to 2010 and assuming an increase in temperature in line with the more extreme scenarios of climate change.

There has been a lot of research into the atmospheric rivers, but it's not clear how they will change as the climate gets warmer and cooler.
Extreme weather conditions could cause dangerous, life-threatening flooding for some regions, and increased rain will be a benefit for others. Climate change and an increase in extreme weather events are linked.
The researchers say that the modeling could apply to other areas. It seems likely that parts of the globe will see a lot more rain in the coming decades, as a result of this and other studies.
In western North America and Europe, interactions between atmospheric rivers and steep mountains play a major role in precipitation.
As the climate warms, these regions may experience more frequent and intense extreme precipitation events.
