These swings trigger changes in atmospheric circulation patterns that, while most prominent in the tropics, also affect circulation patters at higher latitudes as well.

这些改变引发大气环流模式的改变，但是热带地区最显著的改变也影响了高纬度地区的大气环流模式。

That la Nina is now over, according to scientists, but the patterns of atmospheric circulation that were associated with it are persisting, which could account for some of the drought.

根据科学家所言，此现象现在已经结束，但与其相关联的大气流通模式仍旧留存，而这可以用来解释部分的旱情。

World weather patterns will also start to change, as a frigid Antarctic continent and the icy ocean currents that surround it play an important role in global atmospheric and oceanic circulation.

处于严寒地带的南极大陆和周围冰冷的海洋气流，在全球气温和海洋循环方面扮演着重要角色，因此世界的天气状态也要开始变化。

By analysing atmospheric circulation patterns, Dr Marinoni and her colleagues found that winds could bring soot and dust from as far away as Europe, the Middle East and North Africa.
