text: Cumulus parameterization (CP) in state‐of‐the‐art global climate models is
based on the quasi‐equilibrium assumption (QEA), which views convection as the
action of an ensemble of cumulus clouds, in a state of equilibrium with respect
to a slowly varying atmospheric state. This view is not compatible with the organization
and dynamical interactions across multiple scales of cloud systems in the tropics
and progress in this research area was slow over decades despite the widely recognized
major shortcomings. Novel ideas on how to represent key physical processes of
moist convection‐large‐scale interaction to overcome the QEA have surged recently.
The stochastic multicloud model (SMCM) CP in particular mimics the dynamical interactions
of multiple cloud types that characterize organized tropical convection. Here,
the SMCM is used to modify the Zhang‐McFarlane (ZM) CP by changing the way in
which the bulk mass flux and bulk entrainment and detrainment rates are calculated.
This is done by introducing a stochastic ensemble of plumes characterized by randomly
varying detrainment level distributions based on the cloud area fraction of the
SMCM. The SMCM is here extended to include shallow cumulus clouds resulting in
a unified shallow‐deep CP. The new stochastic multicloud plume CP is validated
against the control ZM scheme in the context of the single column Community Climate
Model of the National Center for Atmospheric Research using data from both tropical
ocean and midlatitude land convection. Some key features of the SMCM CP such as
it capability to represent the tri‐modal nature of organized convection are emphasized.

text: The Tibetan plateau (TP) plays an important role in the Asian summer monsoon
(ASM) dynamics as a heat source during the pre-monsoon and monsoon seasons. A
significant contribution to the pre-monsoon TP heating comes from the sensible
heat flux (SHF), which depend on the surface properties. A glaciated surface would
have a different SHF compared to a non-glaciated surface. Therefore, the TP glaciers
potentially can also impact the hydrological cycle in the Asian continent by impacting
the ASM rainfall via its contribution to the total plateau heating. However, there
is no assessment of this putative link available. Here, we attempt to qualitatively
study the role of TP glaciers on ASM by analyzing the sensitivity of an atmospheric
model to the absence of TP glaciers. We find that the absence of the glaciers
is most felt in climatologically less snowy regions (which are mostly located
at the south-central boundary of the TP during the pre-monsoon season), which
leads to positive SHF anomalies. The resulting positive diabatic heating leads
to rising air in the eastern TP and sinking air in the western TP. This altered
circulation in turn leads to a positive SHF memory in the western TP, which persists
until the end of the monsoon season. The impact of SHF anomalies on diabatic heating
results in a large-scale subsidence over the ASM domain. The net result is a reduced
seasonal ASM rainfall. Given the relentless warming and the vulnerability of glaciers
to warming, this is another flag in the ASM variability and change that needs
further attention.

text: "We investigate how mesoscale circulations associated with convective aggregation
can modulate the sensitivity of the hydrologic cycle to warming. We quantify changes
in the full distribution of rain across radiative‐convective equilibrium states
in a cloud‐resolving model. For a given SST, the shift in mean rainfall between
disorganized and organized states is associated with a shift in atmospheric radiative
cooling, and is roughly analogous to the effect of a 4K SST increase. With rising
temperatures, the increase in mean rain rate is insensitive to the presence of
organization, while extremes can intensify faster in the aggregated state, leading
to a faster amplification in the sporadic nature of rain. When convection aggregates,
heavy rain is enhanced by 20‐30% and nonlinear behaviors are observed as a function
of SST and strength of aggregation feedbacks. First, radiative‐ and surface‐flux
aggregation feedbacks have multiplicative effects on extremes, illustrating a
non‐trivial sensitivity to the degree of organization. Second, alternating Clausius‐Clapeyron
and super‐Clausius‐Clapeyron regimes in extreme rainfall are found as a function
of SST, corresponding to varying thermodynamic and dynamic contributions, and
a large sensitivity to precipitation efficiency variations in some SST ranges.\r\nThe
potential for mesoscale circulations in amplifying the hydrologic cycle is established.
However these nonlinear distortions question the quantitative relevance of idealized
self‐aggregation. This calls for a deeper investigation of relationships which
capture the coupling between global energetics, aggregation feedbacks and local
convection, and for systematic tests of their sensitivity to domain configurations,
surface boundary conditions, microphysics and turbulence schemes."

text: This study investigates the feedbacks between an interactive sea surface temperature
(SST) and the self‐aggregation of deep convective clouds, using a cloud‐resolving
model in nonrotating radiative‐convective equilibrium. The ocean is modeled as
one layer slab with a temporally fixed mean but spatially varying temperature.
We find that the interactive SST decelerates the aggregation and that the deceleration
is larger with a shallower slab, consistent with earlier studies. The surface
temperature anomaly in dry regions is positive at first, thus opposing the diverging
shallow circulation known to favor self‐aggregation, consistent with the slower
aggregation. But surprisingly, the driest columns then have a negative SST anomaly,
thus strengthening the diverging shallow circulation and favoring aggregation.
This diverging circulation out of dry regions is found to be well correlated with
the aggregation speed. It can be linked to a positive surface pressure anomaly
(PSFC), itself the consequence of SST anomalies and boundary layer radiative cooling.
The latter cools and dries the boundary layer, thus increasing PSFC anomalies
through virtual effects and hydrostasy. Sensitivity experiments confirm the key
role played by boundary layer radiative cooling in determining PSFC anomalies
in dry regions, and thus the shallow diverging circulation and the aggregation
speed.

text: The goal of this study is to understand the mechanisms controlling the isotopic
composition of the water vapor near the surface of tropical oceans, at the scale
of about a hundred kilometers and a month. In the tropics, it has long been observed
that the isotopic compositions of rain and vapor near the surface are more depleted
when the precipitation rate is high. This is called the “amount effect.” Previous
studies, based on observations or models with parameterized convection, have highlighted
the roles of deep convective and mesoscale downdrafts and rain evaporation. But
the relative importance of these processes has never been quantified. We hypothesize
that it can be quantified using an analytical model constrained by large‐eddy
simulations. Results from large‐eddy simulations confirm that the classical amount
effect can be simulated only if precipitation rate changes result from changes
in the large‐scale circulation. We find that the main process depleting the water
vapor compared to the equilibrium with the ocean is the fact that updrafts stem
from areas where the water vapor is more enriched. The main process responsible
for the amount effect is the fact that when the large‐scale ascent increases,
isotopic vertical gradients are steeper, so that updrafts and downdrafts deplete
the subcloud layer more efficiently.

text: Nearly all regions in the world are projected to become dryer in a warming
climate. Here, we investigate the Mediterranean region, often referred to as a
climate change “hot spot”. From regional climate simulations, it is shown that
although enhanced warming and drying over land is projected, the spatial pattern
displays high variability. Indeed, drying is largely caused by enhanced warming
over land. However, in Northern Europe, soil moisture alleviates warming induced
drying by up to 50% due to humidity uptake from land. In already arid regions,
the Mediterranean Sea is generally the only humidity source, and drying is only
due to land warming. However, over Sahara and the Iberian Peninsula, enhanced
warming over land is insufficient to explain the extreme drying. These regions
are also isolated from humidity advection by heat lows, which are cyclonic circulation
anomalies associated with surface heating over land. The cyclonic circulation
scales with the temperature gradient between land and ocean which increases with
climate change, reinforcing the cyclonic circulation over Sahara and the Iberian
Peninsula, both diverting the zonal advection of humidity to the south of the
Iberian Peninsula. The dynamics are therefore key in the warming and drying of
the Mediterranean region, with extreme aridification over the Sahara and Iberian
Peninsula. In these regions, the risk for human health due to the thermal load
which accounts for air temperature and humidity is therefore projected to increase
significantly with climate change at a level of extreme danger.
