Purpose of Review

Understanding the details of the impact of global warming on the North and South America monsoons is of key importance for the well-being of a great number of inhabitants of the Americas. This review deals with the latest research on this topic.

Recent Findings

Combined multiple datasets, high-resolution global climate models and regional convection–permitting models provide new insights on the evolution of the North and South American monsoons under global warming, suggesting a precipitation reduction in the North American Monsoon, the southward shift of the core of the South American Monsoon, and precipitation reduction in the Amazon Basin. These changes are accompanied by increased frequency of extreme precipitation events in both monsoon regions.

Summary

Uncertainty in the response mechanisms to global warming remains high, especially for the North American monsoon. To make progress, the evaluation of local and remote drives is critical, for which we need a combined use of regional and global models.

气候变暖下美洲季风的当前和未来变化

审查目的

了解全球变暖对北美和南美季风的影响的细节对于美洲许多居民的福祉至关重要。这篇评论处理有关该主题的最新研究。

最近的发现

结合多个数据集，高分辨率的全球气候模型和区域对流允许模型，对全球变暖下北美和南美季风的演变提供了新的见解，这表明北美季风的降水减少，即北半球核心的南移南美季风和亚马逊盆地的降水减少。这些变化伴随着两个季风区极端降水事件的发生频率增加。

概要

对全球变暖的反应机制的不确定性仍然很高，尤其是对于北美季风而言。为了取得进步，评估本地和远程驱动器至关重要，为此，我们需要结合使用区域和全球模型。
