Fast Adjustments of the Asian Summer Monsoon to Anthropogenic Aerosols
Anthropogenic aerosols are a major factor contributing to human-induced climate change, particularly over the densely populated Asian monsoon region. Understanding the physical processes controlling the aerosol-induced changes in monsoon rainfall is essential for reducing the uncertainties in the future projections of the hydrological cycle. Here we use multiple coupled and atmospheric general ...
متن کاملAnthropogenic aerosols and the weakening of the South Asian summer monsoon.
Observations show that South Asia underwent a widespread summertime drying during the second half of the 20th century, but it is unclear whether this trend was due to natural variations or human activities. We used a series of climate model experiments to investigate the South Asian monsoon response to natural and anthropogenic forcings. We find that the observed precipitation decrease can be a...
متن کاملThe effect of regional changes in anthropogenic aerosols on rainfall of the East Asian Summer Monsoon
The response of East Asian Summer Monsoon (EASM) precipitation to long term changes in regional anthropogenic aerosols (sulphate and black carbon) is explored in an atmospheric general circulation model, the atmospheric component of the UK High-Resolution Global Environment Model v1.2 (HiGAM). Separately, sulphur dioxide (SO2) and black carbon (BC) emissions in 1950 and 2000 over East Asia are ...
متن کاملContribution of Local and Remote Anthropogenic Aerosols to the 20 th century 1 Weakening of the South Asian Monsoon 2
18 The late 20 th century response of the South Asian monsoon to changes in anthropogenic 19 aerosols from local (i.e., South Asia) and remote (i.e., outside South Asia) sources was 20 investigated using historical simulations with a state-of-the-art climate model. The observed 21 summertime drying over India is replaced by widespread wettening once local aerosol emissions 22 are kept at pre-in...
متن کاملDistinct effects of anthropogenic aerosols on the East Asian summer monsoon between multidecadal strong and weak monsoon stages
Because industrial emissions of anthropogenic aerosols over East Asia have greatly increased in recent decades, the interactions between atmospheric aerosols and the East Asian summer monsoon (EASM) have attracted enormous attention. To further understand the aerosol-EASM interaction, we investigate the impacts of anthropogenic aerosols on the EASM during the multidecadal strong (1950–1977) and...
