Abstract. The representations of clouds, aerosols, and cloud–aerosol–radiation impacts remain some the largest uncertainties in climate change, limiting our ability to accurately reconstruct past predict future climate. south-east Atlantic is a region where high atmospheric aerosol loadings semi-permanent stratocumulus clouds are co-located, providing an optimum for studying full range aerosol–radiation aerosol–cloud interactions their perturbations Earth's radiation budget.

Abstract Tropical deep convection can aggregate into large clusters, which have impacts on the local humidity and precipitation. Sea surface temperature (SST) gradients been shown to organize convection, yet there has little work done investigate impact of diabatic heating perturbations in atmosphere aggregation convection. Here we how anomalous atmospheric column, through an idealized aerosol plume, affects existence mechanisms convective non‐rotating, global radiative‐convective...
Abstract Clouds are a key player in the global climate system, affecting atmospheric water and energy budgets, they strongly coupled to large‐scale circulation. Here, we examine co‐variability of budget imbalances three different model configurations–radiative‐convective equilibrium, aqua‐planet, simulations with land. The gradual increase level complexity configuration enables an investigation effects rotation, meridional temperature gradient, land‐sea contrast, seasonal cycle on...

Abstract Convective aggregation is an important atmospheric phenomenon which frequently occurs in idealized models radiative‐convective equilibrium (RCE), where the effects of land, rotation, sea surface temperature gradients, and diurnal cycle are often removed. This triggered maintained by self‐generated radiatively driven circulations, for longwave feedbacks essential. Many questions remain over how driving processes real atmosphere. We approach this question adding a continentally sized,...
<p>The phenomenon of convective aggregation in idealised radiative equilibrium simulations has the ability to change mean state its domain. When compared non-aggregation conditions, these usually have warmer drier atmospheres, with stronger precipitation areas. Many experiments use a fixed sea surface temperature (SST), where higher temperatures generally increase scale aggregation. SST gradients been shown organise convection, yet there no work done investigate impact heating...
<p>The self-aggregation of convection in idealised models has been widely studied. Work done to identify key physical mechanisms responsible for both driving and maintaining aggregation a range radiative-convective equilibrium (RCE) models. These are typically run without any land, rotation, variation sea-surface temperatures (SSTs), or diurnal cycle. Due these idealisations, question the study convective is how processes manifest real-world. Several studies have tried tackle...
