Journal of Advances in Modeling Earth Systems, 2022 This study investigates the effects of resolved deep convection on tropical rainfall and its multi‐scale variability. A series of aquaplanet simulations are analyzed using the Model for Prediction Across Scales‐Atmosphere with horizontal cell spacings ...

Trimodal Characteristics of Tropical Convection [PDF]
Journal of Climate, 1999 It has long been known that trade wind cumulus and deep cumulonimbus represent primary components of the broad spectrum of cumulus clouds in the Tropics, which has led to the concept of a bimodal distribution of tropical clouds. However, recent analyses of shipboard radar data from Tropical Ocean Global Atmosphere Coupled Ocean‐Atmosphere Response ...

Simulating deep convection with a shallow convection scheme [PDF]
Atmospheric Chemistry and Physics, 2011 Convective processes profoundly affect the global water and energy balance of our planet but remain a challenge for global climate modeling. Here we develop and investigate the suitability of a unified convection scheme, capable of handling both shallow ...

Earth and Space Science, 2022 Cirrus clouds of various thicknesses and radiative characteristics extend over much of the tropics, especially around deep convection. They are difficult to observe due to their high altitude and sometimes small optical depths. They are also difficult to

Tropical cirrus clouds of convective and non-convective origins [PDF]
, 2022 Abstract. The occurrence of cirrus clouds in the tropics (24 °S–24 °N) is analyzed using the 2007–2015 monthly data from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and the fifth generation reanalysis product (ERA5) of the European Centre for Medium-Range Weather Forecasts.

Model spread in tropical low cloud feedback tied to overturning circulation response to warming
Nature Communications, 2022 The magnitude of the tropical low cloud feedback, which contributes considerably to uncertainty in estimates of climate sensitivity, is closely linked to tropical deep convection and its effects on the tropical atmospheric overturning circulation.

Tropical mesoscale convective system formation environments
Atmospheric Science Letters, 2023 AbstractMesoscale convective systems (MCSs) in the tropics play an integral role in the water cycle, are associated with local hazardous weather conditions, and have significant remote impacts on the midlatitude jet stream. Although it is known that MCSs occur in relatively moist environments, it is unclear how far in advance favorable ingredients ...

Stochastic and mesoscopic models for tropical convection [PDF]
Proceedings of the National Academy of Sciences, 2002 A new way to parametrize certain aspects of tropical convection through stochastic and mesoscopic models is developed here. The technical idea is to adapt tools from statistical physics and materials science to model important unresolved features of tropical convection.

Shear-convection interactions, and orientation of tropical squall lines [PDF]
Geophysical Research Letters, 2021 Abstract Squall lines are known to be the consequence of the interaction of low‐level shear with cold pools associated with convective downdrafts. Also, as the magnitude of the shear increases beyond a critical shear, squall lines tend to orient themselves.

Influence of stratospheric sudden warming on the tropical intraseasonal convection
Environmental Research Letters, 2020 Madden–Julian oscillation (MJO), the dominant mode of intraseasonal variability in the tropical troposphere, has recently been shown to have a great impact on Northern Hemisphere (NH) extratropical stratosphere.
