Hawaii and rainbows go collectively like two peas in a pod. One in every of Hawaii’s nicknames is the Rainbow State and for those who’ve ever visited Hawaii, you in all probability perceive why it claims that nickname. Along with seeing one if their well-known rainbows in motion, you may need observed rainbows embedded into the tradition, too. Some examples embrace the state’s license plate is adorned with a rainbow, the College of Hawaii makes use of a rainbow as a brand/mascot for his or her sports activities groups and lots of companies use the rainbow of their identify and/or logos.
You is likely to be questioning why is it that Hawaii and rainbows go collectively like two peas in a pod? A professor from the College of Hawaii got down to document the special relationship between Hawaii and rainbows. In his paper, Professor Steven Businger explains why Hawaii is the rainbow capital of the world. That doc goes into numerous scientific element. For extra of a layman’s rationalization, the college printed an abstract article, Secrets of the best rainbows on Earth. Right here’s an excerpt to that publication:
“Hawaiʻi’s location within the subtropical Pacific means the general climate sample is dominated by commerce winds, with frequent rain showers and clear skies between the showers. Businger outlines 4 further elements that assure the prevalence of rainbows all through the islands;
“At night time a heat sea floor heats the ambiance from beneath, whereas radiation to area cools cloud tops, leading to deeper rain showers within the morning that produce rainbows in time for breakfast,” stated Businger.
“A second consider producing frequent rainbows is Hawaiʻi’s mountains, which trigger trade-wind move to be lifted up, forming clouds and producing rain over the mountains and sunshine on the lee aspect. With out mountains, Hawaiʻi can be a desert with a scant 17 inches of annual rainfall, in distinction to the lots of of inches of rain that fall in Hawaiʻi’s mountains yearly.
“A 3rd issue conducive to rainbow sightings is daytime heating, which drives island-scale circulations. During times of lighter winds, showers type over the ridge crests and mountain slopes within the afternoon, leading to prolific rainbows because the Solar units.
“Because of the remoteness of the Hawaiian Islands, the air is exceptionally clear and freed from air pollution, continental mud and pollen. The clear air ensures the looks of brilliant rainbows with a full spectrum of colours.”
So, there you’ve it — there may be scientific proof that Hawaii is a particular place for rainbows.
