Characteristics help Hawaii become the ‘rainbow capital’ of the world

Hawaii, known as the “rainbow capital” of the world, is one of the most ideal places on the planet to see the rainbow. Currently, the archipelago is in the rainy period of winter, which means the ability to catch rainbow is even higher than usual, Independent On February 9 reported.

Rainbow appears so often that they become a common symbol in life in Hawaii. Rainbow images are used to decorate buildings, public buses and standard license plates. Hawaii University sports teams are even named after a rainbow.

Rainbow formed when raindrops refracted the sunlight into a strip of color. The brighter the sunshine, the better the rainbow. When it is sunny and rainy at the same time, they will appear on the opposite side of the sun. Rainbow looks larger and higher in the early morning and late afternoon, when the sun is low.

The breeze of the archipelago brings many showers, alternating with the blue sky enough for the sun to shine, according to Steven Businger, a professor of atmosphere at Hawaii University, Manoa. Hawaii’s fresh air also helps. Other places often have more particles in the air due to dust, pollen and vehicles. The conditions for the rainbow formation are even more ideal in Hawaii’s rainy season, which lasts from October to April.

“Perhaps Hawaii has the most beautiful rainbow on the planet,” Businger said. He created the Rainbowchase app to help people find rainbow in Hawaii.

As a professor in Manoa, Kimberly Carlson saw the rainbow outside his apartment window and wondered how the climate change would affect them. Currently an environmental professor at New York University, she has studied the impact of climate change in the next century.

Carlson’s research team predicted that Brazil, the Mediterranean and a part of the Central Africa would have less rainbow in 2100. They discovered some current places of snow but will receive more rain and have more rainbows More in the future, for example Alaska.

Scientists believe that the Hawaii Islands will continue to be a rich place for rainbow, but in the coming decades, longer droughts can lead to less rainbow in dry, windy, windy areas According to Businger. Hawaii’s Maui Island and Hawaii Island can be seriously affected.

Businger said that the unique experience when the rainbow makes them worth research. “Rainbow is a cultural highlight. We really immerse yourself in the moment of seeing a beautiful rainbow, and it is a rare experience in busy life,” he said.
