Vertical Resolution Impacts Explicit Simulation of Deep Convection
Journal of Advances in Modeling Earth Systems, 2023 The aggregation of tropical convection greatly influences the mean‐state of the atmosphere, altering humidity distributions, total atmospheric radiative cooling, and cloud amounts.

Sensitivity of Convective Self‐Aggregation to Subsidence
Journal of Advances in Modeling Earth Systems, 2022 AbstractSimulations using the convection‐permitting MesoNH model with imposed vertical motion document the influence of large‐scale circulation on convective self‐aggregation. Results show that subsidence favors self‐aggregation in this model and that this sensitivity includes a hysteresis: for weak subsidence, only one stationary state is found ...

The Influence of Convective Aggregation on the Stable Isotopic Composition of Water Vapor
AGU Advances, 2023 Remote sensing datasets of water vapor isotopic composition are used along with objective measures of convective aggregation to better understand the impact of convective aggregation on the atmospheric hydrologic cycle in the global tropics (30°N to 30°S)

Convective aggregation in idealized stochastic models
, 2022 <p>Numerical simulations of radiative-convective equilibrium in high-resolution cloud-resolving models (CRMs) revealed the tendency of atmospheric convection to self-aggregate on periods of several weeks when the domain is sufficiently large.

Distortions of the Rain Distribution With Warming, With and Without Self‐Aggregation
Journal of Advances in Modeling Earth Systems, 2021 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 ...

Ensemble of Radiative‐Convective Equilibrium Simulations Near the Aggregated and Scattered Boundary
Geophysical Research Letters, 2021 An ensemble of 10 radiative‐convective equilibrium (RCE) simulations near the sharp transition zone between scattered and aggregated states are examined in a square‐domain cloud‐resolving model.

Journal of Advances in Modeling Earth Systems, 2020 The Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP) consists of simulations at three fixed sea‐surface temperatures (SSTs: 295, 300, and 305 K) and thus allows for a calculation of the climate feedback parameter based on the ...

Ascending Columns, WTG, and Convective Aggregation [PDF]
Journal of the Atmospheric Sciences, 2021 AbstractAnalytic solutions are derived for a convecting atmosphere with mean ascent using a zero-buoyancy bulk-plume approximation for moist convection. It has been suggested that such solutions should serve as a model for the relationship between humidity, instability, and precipitation in the tropics, but it is shown here that this interpretation is ...

Geophysical Research Letters, 2022 The nature of convective organization remains elusive, despite its importance in understanding the role of clouds in climate systems. This study reports a new type of large‐scale structure formed by the self‐organization of deep moist atmospheric ...
