Impacts of Anthropogenic Forcings and El Niño on Chinese Extreme Temperatures [PDF]

Advances in Atmospheric Sciences, 2018
AbstractThis study investigates the potential influences of anthropogenic forcings and natural variability on the risk of summer extreme temperatures over China. We use three multi-thousand-member ensemble simulations with different forcings (with or without anthropogenic greenhouse gases and aerosol emissions) to evaluate the human impact, and with ...

Anthropogenic aerosol radiative forcing in Asia derived from regional models with atmospheric and aerosol data assimilation [PDF]

Atmospheric Chemistry and Physics, 2010
An estimate of monthly 3-D aerosol solar heating rates and surface solar fluxes in Asia from 2001 to 2004 is described here. This product stems from an Asian aerosol assimilation project, in which a) the PNNL regional model bounded by the NCEP reanalyses

Climatic effects of 1950–2050 changes in US anthropogenic aerosols – Part 1: Aerosol trends and radiative forcing [PDF]

Atmospheric Chemistry and Physics, 2012
We calculate decadal aerosol direct and indirect (warm cloud) radiative forcings from US anthropogenic sources over the 1950–2050 period. Past and future aerosol distributions are constructed using GEOS-Chem and historical emission inventories and future

Major factors of global and regional monsoon rainfall changes: natural versus anthropogenic forcing

Environmental Research Letters, 2020
A number of studies have investigated the mechanisms that determine changes in precipitation, including how a wet region gets wetter. However, not all monsoon areas get wetter—there is a need to understand the major factors behind changes in regional ...

Marine ecosystems’ responses to climatic and anthropogenic forcings in the Mediterranean

Progress in Oceanography, 2011
The semi-enclosed nature of the Mediterranean Sea, together with its smaller inertia due to the relative short residence time of its water masses, make it highly reactive to external forcings, in particular variations of water, energy and matter fluxes at the interfaces.

The Northwestern Pacific Warming Record in August 2020 Occurred Under Anthropogenic Forcing

Geophysical Research Letters, 2020
In August 2020, the northwestern Pacific (NWPac; 120°E‐180°E, 20°N‐35°N) experienced its highest sea surface temperature (SST). Although the NWPac Ocean has warmed due to human‐induced greenhouse forcing since the mid‐20th century, the extent to which ...

The role of anthropogenic aerosol forcing in the 1850–1985 strengthening of the AMOC in CMIP6 historical simulations

Journal of Climate, 2022
Previous work has shown that anthropogenic aerosol (AA) forcing drives a strengthening in the Atlantic Meridional Overturning Circulation (AMOC) in CMIP6 historical simulations over 1850–1985, but the mechanisms have not been fully understood.

Anthropogenic forcing intensified internally driven concurrent heatwaves in August 2022 across the Northern Hemisphere

npj Climate and Atmospheric Science
In August 2022, unprecedented and long-lasting extreme heatwaves attacked the Northern Hemisphere, with simultaneous record-breaking surface air temperature (SAT) in Eastern Europe (EE), Southern China (SC), and Western North America (WNA).

Anthropogenic forcing leads to an abrupt shift to phytoplankton dominance in a shallow eutrophic lake

Freshwater Biology
The timing and causes of lake eutrophication are often obscured when multiple anthropogenic disturbances coincide in space and time. This issue is particularly problematic for shallow lakes in arid regions that experience strong climatic forcing which

Long-term precipitation in Southwestern Europe reveals no clear trend attributable to anthropogenic forcing

Environmental Research Letters, 2020
We present a long-term assessment of precipitation trends in Southwestern Europe (1850–2018) using data from multiple sources, including observations, gridded datasets and global climate model experiments.
