追逐彩虹 Chasing rainbows

寻找彩虹日

每年的4月3日是美国的国家寻找彩虹日。阳穿过空中的小水珠时,小水珠就成了天然的透镜,这些彩色的奇观就产生了。彩虹是阳光的折射产生的,因此彩虹永远都在太阳的对面。

夏威夷是经常出现彩虹。在大岛上的霍瑙瑙国家历史公园,这里的山地地形、干净的空气和风形成了产生彩虹的完美环境。

National Find a Rainbow Day

Happy National Find a Rainbow Day!  These colorful natural marvels appear when light strikes water droplets, creating a natural prism effect. So, areas that have plenty of sunshine and showers are a good place to start your search.

And where better to look than Hawaii, said to be the rainbow capital of the world? At Pu'uhonua o Hōnaunau National Historical Park on the Big Island, a combination of mountains, clear air, and trade winds bringing rain showers helps create the perfect conditions for rainbow sightings.
