Colorful wave crashing12/30/2023 ![]() Morning Glory clouds are a specific and more unusual type of roll clouds, which are more common, and not usually as long.

He cautioned, however, that temperature observations remain inconclusive.īut the truth could be far more complex, and there are many other theories about these clouds. “The prevailing theory and most plausible explanation is that CO2 buildup, at 50 miles above the surface, would cause the temperature decrease,” said James Russell, an atmospheric scientist at Hampton University and the principal investigator of an ongoing NASA satellite mission to study the clouds. At the outside edge of the atmosphere, that actually means that it’s getting colder because it’s pushed farther out into space. Right now, during the northern hemisphere’s summer, the atmosphere is heating up and expanding. The clouds form at temperatures around minus-230 degrees Fahrenheit, when dust blowing up from below or falling into the atmosphere from space provides surfaces for water vapor to condense on and freeze. Nobody knows for sure, but most of the answers seem to point to human-caused global atmospheric change. It’s not clear why these clouds have migrated down from the poles, or why more of them are appearing in the polar regions, too, and shining more brightly. They shine because they are so high they remain lit by the sun even after it has gone below the horizon. These "night shining" clouds are formed by ice at the boundary of Earth’s atmosphere and space, 50 miles high. ![]() We became aware of noctilucent clouds here at Wired Science in July when the strange glowing clouds began appearing over the United States and Europe, much farther south than they were normally seen. "It's nothing more mysterious than things freezing." "If you have very strong convection, pushing quickly and very high, it forms more of an ice cloud because it is high enough for the crystals to freeze," Chuang said. "And as soon as it cools enough for a cloud to form, you get these cloud caps."Ĭhuang says pileus clouds look similar to the smooth caps sometimes seen on top of cumulus clouds, which are actually ice caps. "You can see them very commonly above thunderstorms storms, and that's because the air is moving so rapidly up there that the air flow gets perturbed above it," Breed said. In each case, something pushes warm, moist air upward quickly. Situations where this occurs include quickly growing thunderheads, volcanic eruptions and even nuclear explosions. Waves Tattoo Design Image Source: tattooistzitae This tattoo will suit your sentimental side. Bigger and more dramatic designs, such as across your entire chest or back done in height blue color can go for up to 200. This type of cloud is caused by strong, relatively fast upward motion. Expect to pay around 70 for a super small and subtle black and white wave tattoo.
