trung tầng
Definition
- Noun:
- Middle cloud layer: In meteorology, "trung tầng" refers specifically to clouds that form at a medium altitude in the Earth's atmosphere. The term is a technical compound of "trung" (middle) and "tầng" (layer/level).
- Middle layer / intermediate stratum: In a broader, non-meteorological context, it can describe any intermediate layer or middle tier within a stratified system, such as in geology or social structures.
Usage Examples
- Noun (Meteorology):
- Dự báo thời tiết cho biết sẽ có mây trung tầng vào chiều nay. (The weather forecast indicates there will be middle-level clouds this afternoon.)
- Noun (General):
- Tầng đá vôi này nằm ở trung tầng của dãy núi. (This limestone layer is located in the middle stratum of the mountain range.)
Advanced Usage
- The word is most commonly and correctly used in the compound form "mây trung tầng" (altostratus or altocumulus clouds). Using "trung tầng" alone is rare and highly technical; it is typically understood as an abbreviation of the full meteorological term.
- Các đám mây trung tầng thường có màu xám hoặc trắng. (Middle-level clouds are often gray or white.)
Variants and Related Words
- Mây trung tầng (n): Altostratus/Altocumulus clouds. This is the standard and complete term.
- Tầng trung lưu (n): The mesosphere (atmospheric layer). Note: This is a different, specific atmospheric layer, not a cloud type.
- Tầng giữa (n): The middle layer (a more general synonym).
Synonyms
- Middle layer: A general translation for the non-meteorological sense.
- Altostratus/Altocumulus: The specific cloud types for the meteorological sense (when part of "mây trung tầng").
Notes on Usage
- "Trung tầng" is almost never used in isolation in everyday language. It is a specialized term. Learners should treat it as a component of the compound "mây trung tầng".
- In non-scientific contexts, using more general terms like "lớp giữa" or "tầng giữa" is more natural and understandable.
