Canadian wildfire smoke sparks in the strange clouds of the Arctic

In an unexpected turning point, the wildfire of Canada’s record was associated with the strange atmospheric phenomenon of the Arctic. Japanese researchers found that the smoke particles in the fire in 2023 spread thousands of miles under unusually warm conditions to create ice clouds.

The research published in atmospheric research reveals how the organic carbon particles of Canadian wildfire ride the atmosphere (long and narrow strong water transmission area) to reach the Arctic Ocean. Bingyun far exceeds the warmth required.

Scientists use a combination of drone technology and specialized sensors deployed from the Japanese research ship Mirai. Scientists have detected the concentration of particles in low atmosphere, 100 times higher than the Arctic Sea.

“Dr. Kazutoshi Sato, a particle -based particle counter -recorded particle -based particle -based particles, explained that the particles of the drone -based particles counter -recorded were two levels higher than the average sailing average.” “With CPS Sonde, we detected the ice clouds in the middle layer in the temperature under the condition of warmth, near the warm and humid air from the middle latitude.”

Traditionally, Bingyun was formed at a temperature below -38 ° C. However, the research team observed the formation of ice at a higher temperature temperature, which indicates that wildfire particles act as catalysts formed by ice crystals. This discovery is of great significance to understanding the Northern Climate Dynamics, because the impact of Bingyun and Water Cloud on the Earth’s energy balance varyingly.

The co -author of the research, Professor Jun Inoue, emphasized the importance of the atmospheric river in the process of the atmospheric river: “The AR incident is a very important event from water transmission from medium latitude to polar regions. Can be transported. “

Researchers use complex tracking methods to trace the paths of these particles back to the source of Canada. The time arrangement is in line with the country’s worst wildfire season, and this season records unprecedented organic carbon released to the atmosphere.

The results of the research show that a complex feedback circuit: As the possibility of severe wildfires increases the climate change, the particles they release may change the cloud formation model in the Arctic and may affect the regional and global climate system. These particles can act as ice-nuclear particles, which can form ice at a temperature that is usually not occurred.

This research is carried out at a crucial moment, because scientists work hard to understand how human activities and natural disasters affect the Arctic climate model. The warming in the Arctic region is about twice the global average, making it particularly sensitive to environmental changes.

This study was conducted in the adventure of Chukchi and BeauFort ocean. The real -time measurement was combined with the atmospheric modeling to comprehensively understand the interaction of the Wildfire’s emissions and the Arctic Cloud system. MiRAI’s research vessel is a floating laboratory, allowing scientists to collect data in the area previously studied by the Arctic Ocean.

This work has received the support of Japanese education, culture, sports, science and technology, and has taken an important step in understanding the long -range impact of wildfire on the global climate system. These discoveries will be published in atmospheric studies in April 2025.

As climate change becomes more and more frequent and strong, understanding of their profound impacts is becoming more and more important for climate modeling and prediction. This study not only clarifies the accident between the formation of wildfire and the formation of the Arctic Cloud, but also emphasizes the necessity of continuing to monitor these complex atmospheric interactions.
