Rainbow capital of the world

4.Rainbow capital of the world:  Due to frequent appearances, a University of Hawaii professor calls Hawaii the "rainbow capital of the world."

• Winter Season: Rainbows are more common during the rainy season (October–April) in Hawaii.
• About formation of Rainbows:

o Sunlight & Raindrops: Rainbows form when raindrops refract sunlight into different colors.

o Best Viewing Time: They appear opposite the sun and seem larger in the early morning and late afternoon.

o Trade Winds’ Role: Hawaii’s trade winds bring small rain showers with enough clear sky for sunlight to create rainbows.

o Clean Air Advantage: Unlike other places, Hawaii has fewer air particles (Dust, Pollen & Pollution), making rainbows more vivid.

• Impact of Climate Change: Some regions (Brazil, the Mediterranean, and Central Africa) may see fewer rainbows by 2100.

o Places with less snow and more rain (e.g., Alaska) may see more rainbows.

o Hawaii’s leeward (dry) sides may experience fewer rainbows due to longer dry spells.
