Enhanced land–sea warming contrast
elevates aerosol pollution in a warmer world
https://www.nature.com/articles/s41558-019-0401-4
[1] Many climate models simulate an increase in anthropogenic aerosol species in response to warming1, particularly over the Northern Hemisphere mid-latitudes during June, July and August.
[2] Recently, it has been argued that this increase in anthropogenic aerosols can be linked to a decrease in wet removal associated with reduced precipitation2, but the mechanisms remain uncertain.
[3] Here, using a state-of-the-art climate model (the Community Atmosphere Model version 5), we expand on this notion to demonstrate that the enhanced aerosol burden and hydrological changes are related to a robust climate change phenomenon—the land–sea warming contrast3,4.
[4] Enhanced land warming is associated with continental reductions in lower-tropospheric humidity that drivedecreases in low clouds—particularly large scale(stratus) clouds—which, in turn, lead to reduced large-scale precipitation and aerosol wet removal.
[5] Idealized model simulations further show that muting the land–sea warming contrast weakens these hydrological changes, thereby suppressing the aerosol increase.
[6] Moreover, idealized simulations that only feature land warming yield enhanced continental aridity and an increase in aerosol burden.
[7] Thus, unless anthropogenic emission reductions occur, our results add confidence that a warmer world will be associated with enhanced aerosol pollution.

评论:warming contrast是对的,但是,实质是temperature contrast
。
[1] Many climate models simulate an increase in anthropogenic aerosol species in response to warming1, particularly over the Northern Hemisphere mid-latitudes during June, July and August.
评论:我会用during June---August。
[2] Recently, it has been argued that this increase in anthropogenic aerosols can be linked to a decrease in wet removal associated with reduced precipitation2, but the mechanisms remain uncertain.
评论:这句话与上一句衔接得比较“硬”。我会用This increase has been linked to …
[3] Here, using a state-of-the-art climate model (the Community Atmosphere Model version 5), we expand on this notion todemonstrate that the enhanced aerosol burden and hydrological changes are related to a robust climate change phenomenon—the land–sea warming contrast3,4.
评论:我会删expand on this notion to。
[4] Enhanced land warming is associated with continental reductions in lower-tropospheric humidity that drivedecreases in low clouds—particularly large scale(stratus) clouds—which, in turn, lead to reduced large-scale precipitation and aerosol wet removal.
评论:这里的large scale(stratus) clouds应该用large-scale (stratus) clouds,尤其是后面用了large-scale precipitation。Be consistent!
that drivedecreases in low clouds是定continental reductions,我会用“,which cause decreases in low clouds”。
[5] Idealized model simulations further show that muting the land–sea warming contrast weakens these hydrological changes, thereby suppressing the aerosol increase.
[6] Moreover, idealized simulations that only feature land warming yield enhanced continental aridity and an increase in aerosol burden.
评论:我看不懂这个与【4】有什么差别。
[7] Thus, unless anthropogenic emission reductions occur, our results add confidence that a warmer world will be associated with enhanced aerosol pollution.
评论:unless anthropogenic emission reductions occur有点怪,我会用unless we reduce anthropogenic emissions。
