This morning, Zhuzhou was enveloped in a dense fog. In the mist, the buildings were faintly visible, resembling a fairyland. At dawn on December 22, an advection fog covered the city of Zhuzhou in Hunan province, creating a rare and spectacular sea of clouds. Around 7 o'clock that morning, a citizen ascended to the rooftop of Zhujiang Liyuan for a distant view. They saw the houses by the roadside and in the neighborhoods cloaked in thick fog, appearing and disappearing as if they were transforming endlessly, just like a paradise on earth.
Even more peculiar was the sight of a red sun rising slowly from the east through the misty curtain while a full moon still hung leisurely in the western sky above the fog. Advection fog is rare itself, but the spectacle of the sun and moon shining together in such heavy fog is even rarer. Under the gentle breeze, the advection fog draped in rosy light undulated slowly like sea waves, as pure and white as snow peaks. Such poetic and picturesque scenery couldn't help but make one feel ethereal.
According to meteorological data, advection fog is a special weather phenomenon that usually occurs in winter, lasting relatively long periods, covering large areas with dense fog sometimes reaching hundreds of meters in height. It is formed when water vapor meets under conditions of contrasting temperatures. It's understood that in China's Bohai Sea and Yellow Sea regions, advection fog, along with mirages and "Hai Zi" phenomena, are known as the three great maritime wonders.
The "advection fog" weather event in Zhuzhou lasted for over two hours before dissipating at around 10 o'clock.
