?[?ɑ?kt?k ??s??le??(?)n]

Arctic-Oscillation refers to the atmospheric circulation pattern that occurs in the Northern Hemisphere, particularly in the Arctic region. It is characterized by fluctuations in air pressure and wind patterns that can greatly influence weather conditions and climate.

Pronunciation: [?ɑ?kt?k ??s??le??(?)n]

Usage: The Arctic-Oscillation is a key factor in understanding and predicting weather patterns in the Northern Hemisphere.

Example Sentences:

1. The recent changes in the Arctic-Oscillation have led to unusually warm temperatures in the northern regions.

最近北半球氣候振蕩的變化導致了北部地區(qū)異常溫暖的氣溫。

2. The Arctic-Oscillation index is used by meteorologists to track and monitor changes in atmospheric circulation.

氣象學家使用北極振蕩指數(shù)來追蹤和監(jiān)測大氣環(huán)流的變化。

3. The strength of the Arctic-Oscillation can greatly impact the severity of winter storms in certain regions.

北極振蕩的強弱可以極大地影響某些地區(qū)冬季風暴的嚴重程度。

4. A positive Arctic-Oscillation index indicates stronger westerly winds, while a negative index suggests weaker winds and a higher likelihood of cold outbreaks.

正值北極振蕩指數(shù)表明西風更強勁，而負值則意味著風力較弱，更容易出現(xiàn)寒流。

5. The Arctic-Oscillation has a significant impact on sea ice extent and melting rates in the Arctic region.

北極振蕩對北極地區(qū)海冰范圍和融化速度有著重大影響。

Synonyms: Arctic Oscillation, AO

Summary:

The Arctic-Oscillation is an important atmospheric circulation pattern in the Northern Hemisphere that can greatly influence weather conditions and climate. It is characterized by fluctuations in air pressure and wind patterns and is closely monitored by meteorologists to predict changes in weather patterns. Its impact on sea ice extent and melting rates in the Arctic region make it a key factor in understanding climate change.
