The formation of a rainbow depends on two main factors: sunbeams and air humidity. The larger the number of droplets suspended in the air, the greater the chance of this phenomenon happening, so it is much more common after a rain. The white light from the rays is deflected by the edges of the droplets and breaks down into the colors that make up the rainbow.

Usually, the duration of the phenomenon is not very long: in just over an hour, the rainbows disappear in most cases. However, under rare circumstances it may extend longer, and the Guinness Book records a 6-hour phenomenon in Yorkshire, England, in 1994, as the longest ever recorded.

Now that record may have been broken: from 6:57 am on November 30th until 3:55 pm that afternoon, a rainbow enchanted the Taiwanese sky near Taipei University of Chinese Culture. It was almost 9 hours long, which would increase the record by 50%!

Professor Chou Kun-hsuan now seeks Guinness recognition

"It was amazing. It looked like a gift from heaven. It's so rare! ”Cheered Chou Kun-hsuan, professor at the university's Department of Atmospheric Sciences. According to him, the monsoon phenomenon created a moisture bubble in the air, forming clouds that were not dispersed by the lack of winds that day.

When Kun-hsuan noted the beauty of the phenomenon, he called on everyone to try to register as much as possible to claim a quote from the Guinness Book. The conditions for such a long-lasting event could also serve to attract more tourists to Taipei, the city with “the most amazing rainbows in the world” - opinion of the residents themselves, of course.
