Mass mirage in China

Thousands of tourists saw a mirage of very high clarity which lasted four hours off the shore of Penglai city in China. The mist rose on the shore and created an image of a modern city with high rise buildings, wide city streets, fast moving cars, and crowds of people all over the place. The detail was very visible. Experts explained that a mirage is formed when moisture in the air becomes warmer than the temperature of sea water, which refracts rays of sunlight to create reflections of the landscape in the sky.
