That information enables researchers to determine rainfall patterns over the millennia.

这些信息使研究人员能够确定几千年来的降雨模式。

But, at the very least, rainfall patterns across North America, Europe and Africa are likely to increase.

但是，至少，北美、欧洲和非洲的降雨模式可能会增加。

Relief rain is common in mountainous areas where it can lead to more extreme local rainfall patterns, because the rain clouds form very quickly.

地形雨在山区很常见，它可以导致更极端的局部降雨，因为雨云形成非常快。

Greenland ice cores show the temperatures there changing by as much as fifteen degrees in ten years, drastically altering rainfall patterns and growing conditions.

格陵兰的冰核显示，那里的气温在10年内改变了8摄氏度之多。气温的变化改变了那里的降水形式，也改变了那里的生长环境。

A study published in 2016, for example, estimated that shifts in temperature and rainfall patterns could, by 2069, decrease chickpea yield in parts of the world by almost 20%.

例如，2016年发表的一项研究估计，到2069年，气温和降雨模式的变化可能使世界部分地区鹰嘴豆产量下降近20%。
