Nine years after first being submitted, this odd cloud formation was finally accepted by the International Cloud Atlas of the World Meteorological Organization in 2017. It was the first addition since 1951. What’s unique about these clouds is that they are undulate (or wave up and down), and quite honestly, they are kind of creepy and ominous. These clouds are typically low-lying and form in wave-like weather fronts.
