The 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 کاملMechanisms of Asian Summer Monsoon Changes in Response to Anthropogenic Forcing in CMIP5 Models*
Changes of the Asian summer monsoon in response to anthropogenic forcing are examined using observations and phase 5 of the Coupled Model Intercomparison Project (CMIP5) multimodel, multirealization ensemble. In the twentieth century, CMIP5 models indicate a predominantly drying Asian monsoon, while in the twenty-first century under the representative concentration pathway 8.5 (RCP8.5) scenario...
متن کاملLocal versus regional-scale characteristics of monsoon onset and post-onset rainfall over Indonesia
The austral summer monsoon onset and post-onset rainfall and their associated low-level winds are analyzed during the August-February season over Indonesia from 1979 to 2006 using surface and satellite products as well as reanalyses and regional climate model simulations. Onset date is defined using a local agronomic definition. Its leading empirical orthogonal function is found to exhibit a re...
متن کاملContributions of natural and anthropogenic forcing to changes in temperature extremes over the United States
[1] Observations averaged over the U.S. for the second half of the 20th century have shown a decrease of frost days, an increase in growing season length, an increase in the number of warm nights, and an increase in heat wave intensity. For the first three, a nine member multi-model ensemble shows similar changes over the U.S. in 20th century experiments that combine anthropogenic and natural f...
متن کاملComment on "Contributions of anthropogenic and natural forcing to recent tropopause height changes".
Pielke and Chase (1) contend that the troposphere has not warmed since 1979, and that tropospheric warming cannot contribute to observed increases in tropopause height (2). They base this contention on the absence of tropospheric warming in thickness data and geopotential heights obtained from the National Center for Environmental Prediction (NCEP) reanalysis, which is a synthesis of in situ ob...
