Evaluating Large‐Domain, Hecto‐Meter, Large‐Eddy Simulations of Trade‐Wind Clouds Using EUREC4A Data
Journal of Advances in Modeling Earth Systems, 2023 The meso‐scale variability in cloudiness of the marine trade‐wind layer is explored with large‐eddy simulations of regional extent and validated against observations of the EUREC4A field campaign.

A coarsening model for self‐organization of tropical convection [PDF]
Journal of Geophysical Research: Atmospheres, 2013 If the influence of humidity on cumulus convection causes moist regions of the tropical troposphere to become moister and dry regions to become drier, and if horizontal mixing of moisture is not rapid enough to overcome this tendency, then the atmosphere will tend to separate into increasingly large moist and dry regions through a process of coarsening.

Organization and Oscillations in Simulated Shallow Convective Clouds [PDF]
Journal of Advances in Modeling Earth Systems, 2018 AbstractPhysical insights into processes governing temporal organization and evolution of cloud fields are of great importance for climate research. Here using large eddy simulations with a bin microphysics scheme, we show that warm convective cloud fields exhibit oscillations with two distinct periods (~10 and ~90 min, for the case studied here).

Organization of convective ascents in a warm conveyor belt [PDF]
Weather and Climate Dynamics, 2020 Warm conveyor belts (WCBs) are warm, moist airstreams of extratropical cyclones leading to widespread clouds and heavy precipitation, where associated diabatic processes can influence midlatitude dynamics.

Environmental Conditions Associated with Horizontal Convective Rolls, Cellular Convection, and No Organized Circulations [PDF]
Monthly Weather Review, 2021 AbstractTypical environmental conditions associated with horizontal convective rolls (HCRs) and cellular convection have been known for over 50 years. Yet our ability to predict whether HCRs, cellular convection, or no discernable organized (null) circulation will occur within a well-mixed convective boundary layer based upon easily observed ...

Journal of Advances in Modeling Earth Systems, 2021 In the atmosphere, convection can organize from smaller scale updrafts into more coherent structures on various scales. In bulk‐plume cumulus convection parameterizations, this type of organization has to be represented in terms of how the resolved flow ...

Forcing and Organization of Convective Systems
Meteorological Monographs, 2003 Perhaps as in no other area of meteorology, radar has proven to be the key tool in modern detection and forecasting, as well as in identifying and understanding the physics, of convective storms and convective systems. From its initial deployment as a research tool following the second World War [see the excellent review of the history of radar ...

Effects of Convectively Generated Gravity Waves and Rotation on the Organization of Convection
Journal of the Atmospheric Sciences, 2004 Abstract The effects of latent heating, gravity waves, and planetary rotation on numerically simulated convective cloud systems are investigated. First, the nonlinear response of an initially motionless, uniformly stratified, dry atmosphere to steady heating that interacts with the environment through inertial–gravity waves is examined.
