Taiwan Sees World Record Breaking Nine Hour Rainbow
Students and professors at Taipei's Chinese Culture University were shocked and delighted by a rainbow that lasted for a whopping nine hours last Thursday, the longest recorded time for such a phenomenon.
Rainbows usually last for no more than an hour at a time and often much less. The current Guinness World Records holder is at six hours which was set on 14 March 1994 in Yorkshire, England. Observers of this latest rainbow will need to gather evidence of photos to apply for a new world record.
"It was amazing… It felt like a gift from the sky... It's so rare!" said Chou Kun-hsuan a professor at the university. After the rainbow had stayed put already for four hours, staff and students at the university were notified to take pictures as evidence of the stunning event. "With the 10,000 pictures we took in our department alone, and the many more taken by others on campus and people living nearby, I'm confident we can prove to Guinness second by second that this rainbow lasted for nine hours," Professor Chou said. Evidence of the rainbow shows it lasted from at least 6.57am until 3.55pm, making it 8 hours and 58 minutes and well above the current record.
According to experts, the reason the rainbow lasted for so long was due to a seasonal north-east monsoon that had trapped moisture in the air bringing clouds, sunlight and a slow wind speed of 2.5-5 metres per second.
The professor also mentioned that the previous Monday they had also witnessed a rainbow lasting for six hours brought by similar conditions. "I plan to contact the Taipei City tourism department to promote this, 'you can see a nine-hour rainbow in Taipei in the winter, it's amazing! Come to Taipei!'" He added.
