Did you knew that cloud formations, just like animals or plants have their names and that there is a discipline in science which is dedicated to clouds classification? Cloud formations can be really beautiful and breathtaking but sometimes they can be really scary and dark. However, science tries to explain everything.
We made a short list of some most unusual cloud formations which will make you, if you see them over the sky, stand for a while and just watch.
1. Undulatus asperatus – a cloud formation which is about to be officially accepted as a specie by the Cloud Appreciation Society which would make it the first to be accepted by CLA since 1951. They have wavy undersurface so they literally look like a sea waves just placed on the sky.
2. Roll clouds – Arcus cloud formations – or better known as roll cloud and shelf cloud formations. Roll clouds are formed by outflows of cold air which can come from sea breezed or cold fronts.
3. Shelf clouds – they usually appear at the leading edge of thunderstorm outflow.
4. Mammatus clouds – they are often associated with thunderstorms but they might not necessarily be an indicator for that. They are formed as a result of moist air sinking into dry air.
5. Lenticular clouds – those are spaceship like formations which form at the altitude up to 12 kilometers.
6. Cumulonimbus incus clouds – also known as anvil cloud because it looks from upside just like anvil with its flat top. This cloud shows up when a thunderstorm is in its mature stage.
7. Polar stratospheric clouds – also known as nacreous clouds which can be spotted over the Earth’s poles. The best time to see them is during twilight.
8. Noctilucent clouds – night clouds are best visible in a deep twilight in the nearby of poles, best visible between 50° and 70° north and south of the equator. The noctilucent means shining in the night, this clouds often look like they are some kind of aurora light.
9. Kelvin–Helmholtz clouds – known also as billow or shear-gravity clouds, those are based on Kelvin–Helmholtz instability. This means that those clouds are formed in a similar way in which waves are formed at the sea.
10. Stratocumulus Clouds – those are low-altitude clouds which can be sometimes formed as long ribbons which occurs when they are captured by air currents.
