Time-Delayed Tandem Microwave Observations of Tropical Deep Convection: Overview of the C2OMODO Mission

Frontiers in Remote Sensing, 2022
Convective clouds serve as a primary mechanism for the transfer of thermal energy, moisture, and momentum through the troposphere. Arguably, satellite observations are the only viable way to sample the convective updrafts over the oceans.

A Spectrum of Convective Self‐Aggregation Based on Background Rotation

Journal of Advances in Modeling Earth Systems, 2022
High‐resolution modeling reveals a tendency for deep convection to spontaneously self‐aggregate from radiative‐convective equilibrium. Self‐aggregated convection takes different forms in nonrotating versus rotating environments, including tropical ...

Convective Self‐Aggregation Occurs Without Radiative Feedbacks in Warm Climates

Geophysical Research Letters, 2023
Previous research showed that radiative feedbacks are essential to the spontaneous development of convective aggregation (CSA) in idealized atmosphere models.

Competing Effect of Radiative and Moisture Feedback in Convective Aggregation States in Two CRMs

Journal of Advances in Modeling Earth Systems, 2023
The radiative‐convective equilibrium (RCE) of two models exhibiting convective aggregation has been compared. The goal of the work, following the suggestion from the RCE Model Intercomparison Project (RCEMIP), is to identify key parameters controlling ...

Nonrotating Convective Self‐Aggregation in a Limited Area AGCM

Journal of Advances in Modeling Earth Systems, 2018
AbstractWe present nonrotating simulations with the Goddard Earth Observing System (GEOS) atmospheric general circulation model (AGCM) in a square limited area domain over uniform sea surface temperature. As in previous studies, convection spontaneously aggregates into humid clusters, driven by a combination of radiative and moisture‐convective ...

Aggregation-Based Algebraic Multigrid for Convection-Diffusion Equations

SIAM Journal on Scientific Computing, 2012
We consider the iterative solution of large sparse linear systems arising from the upwind finite difference discretization of convection-diffusion equations. The system matrix is then an M-matrix with nonnegative row sum, and, further, when the convective flow has zero divergence, the column sum is also nonnegative, possibly up to a small correction ...

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

Divergent convective outflow in ICON deep-convection-permitting and parameterised deep convection simulations [PDF]

Weather and Climate Dynamics
Upper-tropospheric deep convective outflows during an event on 10–11 June 2019 over central Europe are analysed in ensembles of the operational Icosahedral Nonhydrostatic (ICON) numerical weather prediction model.

Laser Induced Aggregation of Light Absorbing Particles by Marangoni Convection

Applied Sciences, 2020
Laser induced Marangoni convection can be used to accumulate micro-particles. In this paper, a method is developed to control and accumulate the light absorbing particles dispersed in a thin solution layer. The particles are irradiated by a focused laser

Observed Modulation of the Tropical Radiation Budget by Deep Convective Organization and Lower‐Tropospheric Stability

AGU Advances, 2020
This study analyzes the observed monthly deseasonalized and detrended variability of the tropical radiation budget and suggests that variations of the lower‐tropospheric stability and of the spatial organization of deep convection both strongly ...
