Spontaneous Aggregation of Convective Storms
Annual Review of Fluid Mechanics, 2022 <p>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 results in a state where a moist cloudy region with intense deep convective storms is surrounded by extremely dry subsiding ...

Observing Convective Aggregation [PDF]
Surveys in Geophysics, 2017 Convective self-aggregation, the spontaneous organization of initially scattered convection into isolated convective clusters despite spatially homogeneous boundary conditions and forcing, was first recognized and studied in idealized numerical simulations.

Convective aggregation in realistic convective‐scale simulations [PDF]
Journal of Advances in Modeling Earth Systems, 2017 AbstractTo investigate the real‐world relevance of idealized‐model convective self‐aggregation, five 15 day cases of real organized convection in the tropics are simulated. These include multiple simulations of each case to test sensitivities of the convective organization and mean states to interactive radiation, interactive surface fluxes, and ...

What favors convective aggregation and why? [PDF]
Geophysical Research Letters, 2015 AbstractThe organization of convection is ubiquitous, but its physical understanding remains limited. One particular type of organization is the spatial self‐aggregation of convection, taking the form of cloud clusters, or tropical cyclones in the presence of rotation.

Convective Self-Aggregation in Numerical Simulations: A Review [PDF]
Surveys in Geophysics, 2017 Organized convection in the Tropics occurs across a range of spatial and temporal scales and strongly influences cloud cover and humidity. One mode of organization found is “self-aggregation”, in which moist convection spontaneously organizes into one or several isolated clusters despite spatially homogeneous boundary conditions and forcing.

Convection-Limited Aggregation
Europhysics Letters (EPL), 1995We consider colloidal aggregation in which the rate limiting step is the convective transport of the aggregating species. Simulations of this process in the limit of particle-cluster accretion show that fractal aggregates are formed, with a fractal dimension of around 2.5 in three dimensions, and 1.6 in two dimensions.

<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
