1. A faint, colorless or whitish arc resembling a rainbow, formed by sunlight shining through fog or mist.
Usage: plural of fogbow; meteorological phenomenon; also called a white rainbow or Ulloa's ring

Examples

• The hikers spotted several fogbows in the valley as the morning mist caught the sunlight.
• Unlike rainbows, fogbows appear nearly colorless because the water droplets in fog are too small to refract light effectively.
• Fogbows are most commonly observed in mountainous regions where fog is thick and persistent.
• The photographer waited patiently for the fogbows to appear as the sun broke through the clouds.
• Meteorologists study fogbows to better understand light scattering in water droplets.
