xoáy nghịch
Definition
- Noun (Meteorology):
- Anticyclone: A weather system characterized by high atmospheric pressure at its center, with air descending and flowing outward in a clockwise direction in the Northern Hemisphere (and counterclockwise in the Southern Hemisphere). It is typically associated with calm, stable, and clear weather conditions. This is the direct and primary translation of "xoáy nghịch".
Usage Examples
- Noun:
- Xoáy nghịch đang gây ra thời tiết nắng ráo cho khu vực. (The anticyclone is causing dry, sunny weather for the region.)
- Dự báo cho biết một xoáy nghịch sẽ ảnh hưởng đến miền Trung vào cuối tuần. (The forecast indicates an anticyclone will affect the central region this weekend.)
Advanced Usage
- "Vùng áp cao" (high-pressure area): This is a more general, commonly used term that is functionally synonymous with "xoáy nghịch" in weather contexts. An "xoáy nghịch" describes the specific rotational structure of a high-pressure system.
- Thời tiết ổn định là do ảnh hưởng của một vùng áp cao, hay còn gọi là xoáy nghịch. (The stable weather is due to the influence of a high-pressure area, also called an anticyclone.)
Variants and Related Words
- Xoáy thuận (n): Cyclone or low-pressure system. This is the direct opposite meteorological phenomenon to an "xoáy nghịch".
- Trong khi miền Bắc chịu ảnh hưởng của xoáy nghịch thì miền Nam lại có mưa do xoáy thuận. (While the North is under the influence of an anticyclone, the South has rain due to a cyclone.)
Synonyms
- High-pressure system: A broad term for an area of high atmospheric pressure.
- High: A common abbreviated term in weather forecasting (e.g., "a high over the Pacific").
Related Concepts
