A breathtaking weather phenomenon recently unfolded at Tianchi Lake, located within the Changbai Mountain Nature Reserve in Jilin Province, China. Strong winds combined with a sharp temperature drop created a mesmerizing scene of vapor swirling over the lake’s surface, resembling a boiling pot. This natural spectacle, known as ‘sea smoke,’ occurs when cold air causes water vapor to condense into mist, which then drifts with the wind, forming what is scientifically termed evaporation fog. Experts from the Jilin Provincial Meteorological Observatory explained that the unique conditions at Changbai Mountain contribute to this phenomenon. As cold air descends the volcanic crater and meets the warmer, unfrozen lake surface, the temperature contrast causes the water vapor to condense into fog. The synchronized movement of the water and air further enhances the visual effect, creating a dreamlike and ethereal atmosphere. The Integrated Media Center of Changbai Mountain captured the event on video, showcasing the lake’s natural beauty and the interplay of weather elements. This rare occurrence highlights the dynamic and ever-changing nature of the region’s environment, drawing attention to the wonders of natural phenomena.
