SpaceSundogs and Halos: Exploring Atmospheric Wonders
Sundogs and halos are atmospheric phenomena that occur when sunlight passes through ice crystals in the atmosphere. These events are not only breathtaking but also teach us a lot about atmospheric science.
Sundogs: Colored Spots
Sundogs are colored spots that appear on either side of the Sun. They form when sunlight passes through hexagonal ice crystals and is refracted, creating the bright spots.
Halos: Ring of Light
A halo is a ring of light around the Sun or Moon, formed when light passes through hexagonal ice crystals and is refracted, creating a ring shape.
Properties of Sundogs and Halos
– Color: Sundogs and halos can both display colors, but sundogs typically have red on the inside and blue on the outside.
– Position: Sundogs appear at an angle of about 22 degrees from the Sun.
– Intensity: The intensity of sundogs and halos depends on the concentration of ice crystals and the Sun’s position.
Observing Sundogs and Halos
– Weather Conditions: Sundogs and halos are often seen in cold weather when ice crystals are present in the atmosphere.
– Sun’s Position: The Sun should be high enough in the sky for sundogs and halos to be visible.
– Location: Sundogs and halos are more common in polar regions or at high altitudes where ice crystals are more prevalent.
Sundogs and halos offer a fascinating way to explore atmospheric wonders, providing insights into atmospheric science while showcasing nature’s beauty.
