abstract = "We use an unprecedented ensemble of regional climate model (RCM)
projections over seven regional CORDEX domains to provide, for the
first time, an RCM-based global view of monsoon changes at various
levels of increased greenhouse gas (GHG) forcing. All regional
simulations are conducted using RegCM4 at a 25 km horizontal grid
spacing using lateral and lower boundary forcing from three
General Circulation Models (GCMs), which are part of the fifth
phase of the Coupled Model Inter-comparison Project (CMIP5). Each
simulation covers the period from 1970 through 2100 under two
Representative Concentration Pathways (RCP2.6 and RCP8.5).
Regional climate simulations exhibit high fidelity in capturing
key characteristics of precipitation and atmospheric dynamics
across monsoon regions in the historical period. In the future
period, regional monsoons exhibit a spatially robust delay in the
monsoon onset, an increase in seasonality, and a reduction in the
rainy season length at higher levels of radiative forcing. All
regions with substantial delays in the monsoon onset exhibit a
decrease in pre-monsoon precipitation, indicating a strong
connection between pre-monsoon drying and a shift in the monsoon
onset. The weakening of latent heat driven atmospheric warming
during the pre-monsoon period delays the overturning of
atmospheric subsidence in the monsoon regions, which defers their
transitioning into deep convective states. Monsoon changes under
the RCP2.6 scenario are mostly within the baseline variability.",
