Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

Journal of Advances in Modeling Earth Systems, 2017
Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and convective dynamics ( ∼1 km), which generally requires

Coarse, intermediate and high resolution numerical simulations of the transition of a tropical wave critical layer to a tropical storm [PDF]

Atmospheric Chemistry and Physics, 2010
Recent work has hypothesized that tropical cyclones in the deep Atlantic and eastern Pacific basins develop from within the cyclonic Kelvin cat's eye of a tropical easterly wave critical layer located equatorward of the easterly jet axis.

Quantifying Convective Aggregation Using the Tropical Moist Margin's Length

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 ...

Tropical Cyclogenesis From Self‐Aggregated Convection in Numerical Simulations of Rotating Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems, 2020
In a modeled environment of rotating radiative‐convective equilibrium (RCE), convective self‐aggregation may take the form of spontaneous tropical cyclogenesis. We investigate the processes leading to tropical cyclogenesis in idealized simulations with a

Effects of soil particles and convective transport on dispersion and aggregation of nanoplastics via small-angle neutron scattering (SANS) and ultra SANS (USANS).

PLoS ONE, 2020
Terrestrial nanoplastics (NPs) pose a serious threat to agricultural food production systems due to the potential harm of soil-born micro- and macroorganisms that promote soil fertility and ability of NPs to adsorb onto and penetrate into vegetables and ...

Tipping to an Aggregated State by Mesoscale Convective Systems

Journal of Advances in Modeling Earth Systems
Radiative‐convective equilibrium simulations were suggested to resist self‐aggregation within a linearly stable regime at low surface temperatures. Recent numerical work shows that this linearly stable regime can rapidly transition to an aggregated state

Convective Self‐Aggregation in Diurnally Oscillating Sea Surface Temperature and Solar Forcing Experiments

Journal of Advances in Modeling Earth Systems
We have addressed convective self‐aggregation (CSA) in steady and oscillating sea surface temperature (SST) and solar radiation (SOLIN) cloud‐resolving model simulations in a non‐rotating radiative‐convective equilibrium (RCE) framework.

Convection On the Edge

Journal of Advances in Modeling Earth Systems, 2019
Deep convection over tropical oceans often appears intensified at the edge of convectively active regions, both in idealized studies and in observations.

The Unreasonable Efficiency of Total Rain Evaporation Removal in Triggering Convective Self‐Aggregation

Geophysical Research Letters
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.
