Here's what #asperitas #clouds look like from a distance. Someone southeast of Victoria probably has a photo from underneath them.

These are (obviously? presumably) associated with some gravity wave behaviour of wind interacting with the mountains south of us.

En 2017, l'Atlas international des nuages avait officialisé l'#asperitas, particularité supplémentaire de #nuages. Verrons-nous bientôt l'arrivée du supercilium ou nuage en forme de sourcils?

“Vorticity 6”

It’s time for another storm-chasing timelapse from photographer Mike Olbinski! “Vorticity 6” focuses on supercell thunderstorms and their tornadoes. There’s billowing turbulent convection, undulating asperitas, bulging mammatus, microbursts, and more. There’s nothing like timelapse to highlight the growth, rotation, and shear involved in these storms. (Video and image credit: M. Olbinski)

Asperitas Clouds Over New Zealand

What kind of clouds are these? Although their cause is presently unknown, such unusual atmospheric structures, as menacing as they might seem, do not appear to be harbingers of meteorological doom. Formally recognized as a distinct cloud type only last year, asperitas clouds can be stunning in appearance, unusual in occurrence, and are relatively unstudied.

Mysterious Clouds Stun South Korea from Seoul to Jeju. On May 1 and May 5, 2025, South Korea’s skies became the stage for a rare atmospheric phenomenon: Asperitas clouds.

Äskön kotiin palatessani huomasin, että tyypillisesti tylsän harmaa Stratocumulus stratiformis (Kumpukerrospilvi, kerrosmainen) olikin ottanut yllättäen vähän muunnoksen lacunosus (~kennomainen) näköä pintaan. Voisi siinä tulkita olevan myös hieman lisäosan asperitas (~tyrskyinen) piirteitä, mutta siitä en ole niin varma.
