Abstract

Purpose of Review

During the past decade, weather and climate extremes, enhanced by climate change trends, have received tremendous attention because of their significant impacts on socio-economy, public health, and ecosystems. At the same time, many parts of the world still suffer from severe air pollution issues. However, whether and how air pollutants play a role in weather and climate systems through complex interactions and feedbacks with meteorology and ecosystems remains an open question. So far, only a relatively small number of studies have been conducted to understand and quantify air pollution interactions with weather and climate extremes. As a result, there is limited process-level knowledge of this topic and associated mechanisms. This review paper provides a concise synthesis of recent scientific advances, current knowledge gaps, and future directions on air pollution interactions with weather and climate extremes, such as extreme precipitation, floods, droughts, wildfires, and heat waves.

Recent Findings

There is evidence (albeit limited) that air pollution can contribute to or interact with each of the aforementioned extremes, and several possible mechanisms (e.g., physical, thermodynamical, dynamical, chemical, and ecological processes) have been identified and proposed to explain their relationships. However, there are still substantial knowledge gaps that need to be addressed in future studies, which will benefit from enhanced observational and modeling capabilities as well as interdisciplinary collaborations.

Summary

Overall, the air pollution interactions with weather and climate extremes are currently under-studied and less understood. More future research is needed for process-level investigations to improve the mechanistic understanding on this topic.

空气污染与极端天气和气候的相互作用:当前知识、差距和未来方向
审查目的在过去十年中,极端天气和气候因气候变化趋势而加剧,因其对社会经济、公共健康和生态系统的重大影响而受到极大关注。与此同时,世界上许多地方仍然存在严重的空气污染问题。然而,空气污染物是否以及如何通过与气象学和生态系统的复杂相互作用和反馈作用在天气和气候系统中发挥作用,仍然是一个未决问题。迄今为止,只有相对较少的研究是为了了解和量化空气污染与极端天气和气候之间的相互作用。因此,人们对这一主题和相关机制的过程级知识非常有限。本综述文件简要综述了空气污染与极端天气和气候(如极端降水、洪水、干旱、野火和热浪)之间相互作用的最新科学进展、当前知识差距和未来发展方向。总之,目前对空气污染与极端天气和气候之间的相互作用研究不足,了解较少。未来需要开展更多过程层面的研究,以提高对这一主题的机理认识。
