Self‐Aggregation of Convective Clouds With Interactive Sea Surface Temperature [PDF]
Journal of Advances in Modeling Earth Systems, 2020 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.

Quantifying Convective Aggregation Using the Tropical Moist Margin's Length [PDF]
Journal of Advances in Modeling Earth Systems, 2020 On small scales, the tropical atmosphere tends to be either moist or very dry. This defines two states that, on large scales, are separated by a sharp margin, well identified by the antimode of the bimodal tropical column water vapor distribution ...

A simple model linking radiative–convective instability, convective aggregation and large-scale dynamics [PDF]
Weather and Climate DynamicsA simple model is presented which is designed to analyse the relation between the phenomenon of convective aggregation at small scales and larger-scale variability that results from coupling between dynamics and moisture in the tropical atmosphere.

Aggregation under a forced convective flow [PDF]
Physical Review B, 1992 Morphological transitions are analyzed for a radial multiparticle diffusion-limited aggregation process grown under a convective drift. The introduction of a tangential flow changes the morphology of the diffusion-limited structure, into multiarm structures, inclined opposite to the flow, whose limit consists of single arms, when decreasing density ...

A Shallow Water Model for Convective Self-Aggregation
Journal of the Atmospheric Sciences, 2020 AbstractRandomly distributed convective storms can self-aggregate in the absence of large-scale forcings. Here we present a 1D shallow-water model to study the convective self-aggregation. This model simulates the dynamics of the planetary boundary layer and represents convection as a triggered process.

Numerical Diffusion and Turbulent Mixing in Convective Self‐Aggregation
Journal of Advances in Modeling Earth Systems, 2023 Convective Self‐Aggregation (CSA) is a common feature of idealized numerical simulations of the tropical atmosphere in Radiative‐Convective Equilibrium (RCE).

Convective self–aggregation in a mean flow [PDF]
Atmospheric Chemistry and Physics, 2020 Abstract. Convective self-aggregation is an atmospheric phenomenon found in numerical simulations in a radiative convective equilibrium framework of which configuration captures the main characteristics of the real-world convection in the deep tropics. As tropical deep convection is typically embedded in a large-scale flow, we impose a background mean ...

Circling in on Convective Self‐Aggregation [PDF]
Journal of Geophysical Research: Atmospheres, 2021 AbstractIn radiative‐convective equilibrium simulations, convective self‐aggregation (CSA) is the spontaneous organization into segregated cloudy and cloud‐free regions. Evidence exists for how CSA is stabilized, but how it arises favorably on large domains is not settled. Using large‐eddy simulations, we link the spatial organization emerging from the

, 2020 <p>The phenomenon of convective aggregation in idealised radiative convective equilibrium simulations has the ability to change the mean state of its domain. When compared to non-aggregation conditions, these simulations usually have warmer drier mean atmospheres, with stronger precipitation in the convective areas. Many of these
