low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals
하늘을 온통 뒤덮고 눈이나 비를 가져오는 낮게 깔린 구름은 하늘 전체에 담요나 단층처럼 드리워져 있기 때문에 스트레이터스(stratus) 구름(층운[層雲])이라고 부른다.
The low-lying clouds that cover the whole sky and bring snow or rain are called stratus (layerlike) clouds because they hang like a blanket, or a layer, across the sky.jw2019 jw2019
