Near Future Projection of Indian Summer Monsoon Circulation under 1.5 °C and 2.0 °C Warming

Climate change under a scenario near 1.5 C of global warming: monsoon intensification, ocean warming and steric sea level rise

We present climatic consequences of the Representative Concentration Pathways (RCPs) using the coupled climate model CLIMBER-3α, which contains a statisticaldynamical atmosphere and a three-dimensional ocean model. We compare those with emulations of 19 state-of-the-art atmosphere-ocean general circulation models (AOGCM) using MAGICC6. The RCPs are designed as standard scenarios for the forthco...

NOTES AND CORRESPONDENCE Timing of El Niño–Related Warming and Indian Summer Monsoon Rainfall

The relationship between all-India summer monsoon rainfall (ISMR) and the timing of (El Niño– Southern Oscillation) ENSO-related warming/cooling is investigated, using observational data during the period from 1881 to 1998. The analysis of the evolutions of Indo-Pacific sea surface temperature (SST) anomalies suggests that when ISMR is not below normal despite the co-occurrence of an El Niño ev...

Global warming and the weakening of the Asian summer monsoon circulation: assessments from the CMIP5 models

Changing links between South Asian summer monsoon circulation and tropospheric land-sea thermal contrasts under a warming scenario

[1] Forced with increased greenhouse gases, the South Asian summer monsoon (SASM) circulation weakens in climate models, which appears inconsistent with the projected increases in near-surface land-sea thermal contrasts during the 21st century. Our analysis shows that the SASM intensity positively correlates with the land-sea thermal contrast in both the lowerand upper-troposphere before year 2...

Scenario dependence of future changes in climate extremes under 1.5 °C and 2 °C global warming

The 2015 Paris Agreement aims to limit global warming below 2 °C and pursue efforts to even limit it to 1.5 °C relative to pre-industrial levels. Decision makers need reliable information on the impacts caused by these warming levels for climate mitigation and adaptation measures. We explore the changes in climate extremes, which are closely tied to economic losses and casualties, under 1.5 °C ...
