text: Tropical precipitation extremes and their changes with surface warming are
investigated using global storm resolving simulations and high-resolution observations.
The simulations demonstrate that the mesoscale organization of convection, a process
that cannot be physically represented by conventional global climate models, is
important for the variations of tropical daily accumulated precipitation extremes.
In both the simulations and observations, daily precipitation extremes increase
in a more organized state, in association with larger, but less frequent, storms.
Repeating the simulations for a warmer climate results in a robust increase in
monthly-mean daily precipitation extremes. Higher precipitation percentiles have
a greater sensitivity to convective organization, which is predicted to increase
with warming. Without changes in organization, the strongest daily precipitation
extremes over the tropical oceans increase at a rate close to Clausius-Clapeyron
(CC) scaling. Thus, in a future warmer state with increased organization, the
strongest daily precipitation extremes over oceans increase at a faster rate than
CC scaling.

text: Global storm-resolving models (GSRMs) use strongly refined horizontal grids
compared with the climate models typically used in the Coupled Model Intercomparison
Project (CMIP) but employ comparable vertical grid spacings. Here, we study how
changes in the vertical grid spacing and adjustments to the integration time step
affect the basic climate quantities simulated by the ICON-Sapphire atmospheric
GSRM. Simulations are performed over a 45 d period for five different vertical
grids with between 55 and 540 vertical layers and maximum tropospheric vertical
grid spacings of between 800 and 50 m, respectively. The effects of changes in
the vertical grid spacing are compared with the effects of reducing the horizontal
grid spacing from 5 to 2.5 km. For most of the quantities considered, halving
the vertical grid spacing has a smaller effect than halving the horizontal grid
spacing, but it is not negligible. Each halving of the vertical grid spacing,
along with the necessary reductions in time step length, increases cloud liquid
water by about 7 %, compared with an approximate 16 % decrease for halving the
horizontal grid spacing. The effect is due to both the vertical grid refinement
and the time step reduction. There is no tendency toward convergence in the range
of grid spacings tested here. The cloud ice amount also increases with a refinement
in the vertical grid, but it is hardly affected by the time step length and does
show a tendency to converge. While the effect on shortwave radiation is globally
dominated by the altered reflection due to the change in the cloud liquid water
content, the effect on longwave radiation is more difficult to interpret because
changes in the cloud ice concentration and cloud fraction are anticorrelated in
some regions. The simulations show that using a maximum tropospheric vertical
grid spacing larger than 400 m would increase the truncation error strongly. Computing
time investments in a further vertical grid refinement can affect the truncation
errors of GSRMs similarly to comparable investments in horizontal refinement,
because halving the vertical grid spacing is generally cheaper than halving the
horizontal grid spacing. However, convergence of boundary layer cloud properties
cannot be expected, even for the smallest maximum tropospheric grid spacing of
50 m used in this study.

text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.

text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
positive phases (a joint positive phase). For the monsoons, which are exceptions
in this regard, we found northeast India often gets excess pre-monsoon rainfall.
Further investigation reveals that this excess pre-monsoon rainfall is produced
by the interaction of the large-scale circulation associated with the joint phase
with the mountains in northeast India. We posit that a warmer troposphere, a consequence
of excess rainfall over northeast India, drives a stronger monsoon circulation
and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
rainfall over northeast India can be used for seasonal monsoon rainfall prediction
over central India. Most importantly, its predictive value is at its peak when
the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
monsoon looms over India.

text: The Indian summer monsoon rainfall (ISMR) has been declining since the 1950s.
However, since 2002 it is reported to have revived. For these observed changes
in the ISMR, several explanations have been reported. Among these explanations,
however, the role of the eastern equatorial Indian Ocean (EEIO) is missing despite
being one of the warmest regions in the Indian Ocean, and monotonously warming.
A recent study reported that EEIO warming impacts the rainfall over northern India.
Here we report that warming in the EEIO weakens the low-level Indian summer monsoon
circulation and reduces ISMR. A warm EEIO drives easterly winds in the Indo–Pacific
sector as a Gill response. The warm EEIO also enhances nocturnal convection offshore
the western coast of Sumatra. The latent heating associated with the increased
convection augments the Gill response and the resultant circulation opposes the
monsoon low-level circulation and weakens the seasonal rainfall.

text: We investigate the capabilities of Physics-Informed Neural Networks (PINNs)
to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.
We perform a quantitative analysis of the quality of the reconstructions at various
amounts of low-passed-filtered information and turbulent intensities. We compare
our results with those obtained via nudging, a classical equation-informed data
assimilation technique. At low Rayleigh numbers, PINNs are able to reconstruct
with high precision, comparable to the one achieved with nudging. At high Rayleigh
numbers, PINNs outperform nudging and are able to achieve satisfactory reconstruction
of the velocity fields only when data for temperature is provided with high spatial
and temporal density. When data becomes sparse, the PINNs performance worsens,
not only in a point-to-point error sense but also, and contrary to nudging, in
a statistical sense, as can be seen in the probability density functions and energy
spectra.

text: The El Niño-Southern Oscillation (ENSO) and the Indian summer monsoon (ISM,
or monsoon) are two giants of tropical climate. Here we assess the future evolution
of the ENSO-monsoon teleconnection in climate simulations with idealized forcing
of CO2 increment at a rate of 1% year-1 starting from a present-day condition
(367 p.p.m.) until quadrupling. We find a monotonous weakening of the ENSO-monsoon
teleconnection with the increase in CO2. Increased co-occurrences of El Niño and
positive Indian Ocean Dipoles (pIODs) in a warmer climate weaken the teleconnection.
Co-occurrences of El Niño and pIOD are attributable to mean sea surface temperature
(SST) warming that resembles a pIOD-type warming pattern in the Indian Ocean and
an El Niño-type warming in the Pacific. Since ENSO is a critical precursor of
the strength of the Indian monsoon, a weakening of this relation may mean a less
predictable Indian monsoon in a warmer climate.

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: Squall lines are substantially influenced by the interaction of low-level
shear with cold pools associated with convective downdrafts. Beyond an optimal
shear amplitude, squall lines tend to orient themselves at an angle with respect
to the low-level shear. While the mechanisms behind squall line orientation seem
to be increasingly well understood, uncertainties remain on the implications of
this orientation. Roca and Fiolleau (2020, https://doi.org/10.1038/s43247-020-00015-4)
show that long lived mesoscale convective systems, including squall lines, are
disproportionately involved in rainfall extremes in the tropics. This article
investigates the influence of the interaction between low-level shear and squall
line outflow on squall line generated precipitation extrema in the tropics. Using
a cloud resolving model, simulated squall lines in radiative convective equilibrium
amid a shear-dominated regime (super optimal), a balanced regime (optimal), and
an outflow dominated regime (suboptimal). Our results show that precipitation
extremes in squall lines are 40% more intense in the case of optimal shear and
remain 30% superior in the superoptimal regime relative to a disorganized case.
With a theoretical scaling of precipitation extremes (C. Muller & Takayabu, 2020,
https://doi.org/10.1088/1748-9326/ab7130), we show that the condensation rates
control the amplification of precipitation extremes in tropical squall lines,
mainly due to its change in vertical mass flux (dynamic component). The reduction
of dilution by entrainment explains half of this change, consistent with Mulholland
et al. (2021, https://doi.org/10.1175/jas-d-20-0299.1). The other half is explained
by increased cloud-base velocity intensity in optimal and superoptimal squall
lines.

text: 'Radiative cooling of the lowest atmospheric levels is of strong importance
for modulating atmospheric circulations and organizing convection, but detailed
observations and a robust theoretical understanding are lacking. Here we use unprecedented
observational constraints from subsidence regimes in the tropical Atlantic to
develop a theory for the shape and magnitude of low‐level longwave radiative cooling
in clear‐sky, showing peaks larger than 5–10 K/day at the top of the boundary
layer. A suite of novel scaling approximations is first developed from simplified
spectral theory, in close agreement with the measurements. The radiative cooling
peak height is set by the maximum lapse rate in water vapor path, and its magnitude
is mainly controlled by the ratio of column relative humidity above and below
the peak. We emphasize how elevated intrusions of moist air can reduce low‐level
cooling, by sporadically shading the spectral range which effectively cools to
space. The efficiency of this spectral shading depends both on water content and
altitude of moist intrusions; its height dependence cannot be explained by the
temperature difference between the emitting and absorbing layers, but by the decrease
of water vapor extinction with altitude. This analytical work can help to narrow
the search for low‐level cloud patterns sensitive to radiative‐convective feedbacks:
the most organized patterns with largest cloud fractions occur in atmospheres
below 10% relative humidity and feel the strongest low‐level cooling. This motivates
further assessment of favorable conditions for radiative‐convective feedbacks
and a robust quantification of corresponding shallow cloud dynamics in current
and warmer climates.'

text: Organization – or departure from a random pattern – in tropical deep convection
is heavily studied due to its immediate relevance to climate sensitivity and extremes.
Low-latitude convection has motivated numerical model idealizations, where the
Coriolis force is removed and boundary conditions are simplified spatially and
temporally. One of the most stunning aspects of such idealized simulated cloud
organization is the spontaneous clumping of convection that can occur without
any predetermining external perturbation, such as inhomogeneous surface boundary
conditions or large-scale waves. Whereas individual convective rain cells measure
only few kilometers in horizontal diameter, the clusters they form can often span
hundreds or even thousands of kilometers. Hence, organization may emerge from
the very small scales but can show effects at the synoptic scale. We refer to
such emergent organization as convective self-organization. Convective self-organization
thus features characteristics of emergence, such as non-trivial system-scale pattern
formation or hysteresis. We summarize observational evidence for large-scale organization
and briefly recap classical idealized modeling studies that yield convective self-aggregation
– emergent organization under strongly idealized boundary conditions. We then
focus on developing research, where temporal variation, such as the diurnal cycle,
or two-way interactive surface properties yield distinct organizational modes.
Convectively generated cold pools and mesoscale convective systems, both ubiquitous
in nature, are thereby found to potentially play key roles in promoting – rather
than suppressing – sustained system-scale organization.

abstract:
- lang: eng
text: Two assumptions commonly applied in convection schemes—the diagnostic and
quasi-equilibrium assumptions—imply that convective activity (e.g., convective
precipitation) is controlled only by the large-scale (macrostate) environment
at the time. In contrast, numerical experiments indicate a “memory” or dependence
of convection also on its own previous activity whereby subgrid-scale (microstate)
structures boost but are also boosted by convection. In this study we investigated
this memory by comparing single-column model behavior in two idealized tests previously
executed by a cloud-resolving model (CRM). Conventional convection schemes that
employ the diagnostic assumption fail to reproduce the CRM behavior. The memory-capable
org and Laboratoire de Météorologie Dynamique Zoom cold pool schemes partially
capture the behavior, but fail to fully exhibit the strong reinforcing feedbacks
implied by the CRM. Analysis of this failure suggests that it is because the CRM
supports a linear (or superlinear) dependence of the subgrid structure growth
rate on the precipitation rate, while the org scheme assumes a sublinear dependence.
Among varying versions of the org scheme, the growth rate of the org variable
representing subgrid structure is strongly associated with memory strength. These
results demonstrate the importance of parameterizing convective memory, and the
ability of idealized tests to reveal shortcomings of convection schemes and constrain
model structural assumptions.

text: Squall lines are known to be the consequence of the interaction of low-level
shear with cold pools associated with convective downdrafts. Also, as the magnitude
of the shear increases beyond a critical shear, squall lines tend to orient themselves.
The existing literature suggests that this orientation reduces incoming wind shear
to the squall line, and maintains equilibrium between wind shear and cold pool
spreading. Although this theory is widely accepted, very few quantitative studies
have been conducted on supercritical regime especially. Here, we test this hypothesis
with tropical squall lines obtained by imposing a vertical wind shear in cloud
resolving simulations in radiative convective equilibrium. In the sub-critical
regime, squall lines are perpendicular to the shear. In the super-critical regime,
their orientation maintain the equilibrium, supporting existing theories. We also
find that as shear increases, cold pools become more intense. However, this intensification
has little impact on squall line orientation.

text: The sensitivity of coarse-grained daily extreme precipitation to sea surface
temperature is analyzed using satellite precipitation estimates over the 300–302.5
K range. A theoretical scaling is proposed, linking changes in coarse-grained
precipitation to changes in fine-scale hourly precipitation area fraction and
changes in conditional fine-scale precipitation rates. The analysis reveals that
the extreme coarse-grained precipitation scaling with temperature (∼7%/K) is dominated
by the fine-scale precipitating fraction scaling (∼6.5%/K) when using a 3 mm/h
fine-scale threshold to delineate the precipitating fraction. These results are
shown to be robust to the selection of the precipitation product and to the percentile
used to characterize the extreme. This new coarse-grained scaling is further related
to the well-known scaling for fine-scale precipitation extremes, and suggests
a compensation between thermodynamic and dynamic contributions or that both contributions
are small with respect to that of fractional coverage. These results suggest that
processes responsible for the changes in fractional coverage are to be accounted
for to assess the sensitivity of coarse-grained extreme daily precipitation to
surface temperature.

text: Idealized simulations of the tropical atmosphere have predicted that clouds
can spontaneously clump together in space, despite perfectly homogeneous settings.
This phenomenon has been called self-aggregation, and it results in a state where
a moist cloudy region with intense deep convective storms is surrounded by extremely
dry subsiding air devoid of deep clouds. We review here the main findings from
theoretical work and idealized models of this phenomenon, highlighting the physical
processes believed to play a key role in convective self-aggregation. We also
review the growing literature on the importance and implications of this phenomenon
for the tropical atmosphere, notably, for the hydrological cycle and for precipitation
extremes, in our current and in a warming climate.
