Dream - The appearance of a giant jellyfish-like holey cloud was seen in the sky of Jember, East Java on Tuesday, June 4, 2024. Its unique and rare shape was captured by residents and went viral on social media. In a video uploaded by the Instagram account @magelang_raya, it shows a natural phenomenon of a holey cloud.

In the video, a neatly arranged cloud can be seen in the sky, but there is one part where there is a giant oval-shaped hole that is not filled by other clouds like the ones around it. This has caused a stir among local residents, who are even wondering about the significance of this phenomenon. It is known that this phenomenon of a hole in the cloud occurred in Kaliwates District, Jember.

The following form is often found in altocumulus, cirrocumulus, and stratocumulus cloud layers. The holes in those clouds will be more visible in altocumulus cloud layers when an aircraft flies through thin cumuliform clouds, triggering glaciation.

Glacial creates cloud particles that change from water droplets into ice particles. That is what then triggers a domino effect, creating gaps in the clouds. "Cavum clouds can be found among three types of clouds, namely cirrocumulus, altocumulus, and stratocumulus," said Forecaster BMKG Banyuwangi Pos Meteorology Jember, Hukama Nur Akmal.
