Hail can be detected using radar. On Doppler radar, hail generally sends a return signal that looks like extremely heavy rainfall. Dual-polarization radar technology, used by the NWS, can help tell the difference between hail, ice pellets and rain, and even determine hail size.

“It seems to be associated with the most intense thunderstorms.” He says the green light is often seen in the updraft area of the storm. “It is almost as if the light is shining through the updraft, through the top of the storm and being filtered out on its way through all of the hail and rain in the updraft.

There are a number of theories surrounding the reason for this phenomenom, but the most likely one is that the thunderstorm acts as a filter. One of the wavelengths that makes it through is green. It is very clear that the light is coming from the clouds themselves.

William Beasley, professor of meteorology at the University of Oklahoma, agrees. It all comes down to the moisture particles found in these afternoon thunderstorm clouds. They absorb red light and make the scattered light appear blue. Basically, a hail storm or tornado can happen with or without green clouds.

The purple sky is actually known as scattering, and it occurs when heavy rains rid the atmosphere of larger particles that abord most light. The result is an electric sky, filled with purple and pink colors. While it may be a natural phenomenon, it may also foreshadow devastation to come.

The phenomenon of scattering is also why the sky turns red, orange, and pink at sunset. The science is the same, with short-wavelength blue and violet light scattered by molecules in the atmosphere while longer-wavelength red, orange, and pink light passing through and hitting the clouds.

Scientists have just discovered the world’s oldest colour – and it’s a billion-year-old bright pink

• Science says the oldest colour in the world is bright pink.
• The colour was found in pigments extracted from rocks deep beneath the Sahara desert.
• ANU scientists say the pigments are more than one billion years old.

For an ideal sunrise or sunset, you should look for a high cloud cover. If the clouds are too low, they will block the red and orange colors that we are hoping to see in the sky. We also want to see very puffy clouds. If the cloud cover is too thick, those red and orange wavelengths won’t be able to penetrate them.

Typical pollution droplets such as those found in urban smog or summertime haze are on the order of . Similarly, the vibrant oranges and reds of “clean” sunsets give way to pale yellows and pinks when dust and haze fill the air. But airborne pollutants do more than soften sky colors.

The National Weather Service says orange skies are common following storms that move in just as the sun is setting. Shorter wavelengths of light (blue) are scattered quickly, leaving only the yellow-orange-red end of the spectrum,” the weather service reports.

Besides atmospheric gases, water droplets, and dust particles, air pollutants also determine the sky’s color at sunrise and sunrise. Aerosols suspended in the air scatter sunlight into a band of colors. When there are more aerosols or smog, more sunlight is scattered, resulting in purple or pink sunsets.

The “Belt of Venus” is an atmospheric phenomenon that creates a pink band in the sky at sunrise and sunset. It is actually the area between Earth’s shadow and the blue sky. The belt is similar to alpenglow, which creates a reddish glow just over the horizon.

it’s a transitional phase- day to night..as we know the period of changing from good to bad is very painful..as sun is a sign of positivity and night is a sign of fear to us as well as our ancestors…so may be we evolved like that..that’s why we are painful to sunset..and get depressed.

A lover of sunsets is called an ‘opacarophile’. To understand its roots, the word opacarophile can be broken down into two parts: ‘opacare’ which is Latin for dusk or sunset, and ‘phile’ which is Greek for love.

The long trip leaves the longer wavelength colors (those reds, yellows, and oranges), but scatters the shorter wavelengths out. A few clouds also help the sunrise become more vibrant, but not all types of clouds are good. The best clouds for vibrant colors are the middle-level or high-level clouds.

Low humidity + cleaner air = more intense sunset colors When it’s colder out, it’s generally less humid, meaning there’s less water vapor in the air. But the explanation for why low humidity produces better sunsets is a bit indirect.

During sunrise, sunlight has a longer distance to travel through the sky before it reaches you. The colors that make it to your eyeballs are pinks and oranges and reds, because they are less likely to be scattered by the atmosphere. In turn, the morning sunlight fills the sky with a blaze of pinks and reds.

Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. The result is that the sunlight takes on an orange or red cast, which we can see reflected from clouds or other objects as a colorful sunset (or sunrise).
