Warming-induced contraction of tropical convection delays and reduces tropical cyclone formation [PDF]
Nature Communications, 2023 The future risk of tropical cyclones (TCs) strongly depends on changes in TC frequency, but models have persistently produced contrasting projections. A satisfactory explanation of the projected changes also remains elusive.

Modelling deep convection and its impacts on the tropical tropopause layer [PDF]
Atmospheric Chemistry and Physics, 2010 The UK Met Office's Unified Model is used at a climate resolution (N216, ~0.83°×~0.56°, ~60 km) to assess the impact of deep tropical convection on the structure of the tropical tropopause layer (TTL). We focus on the potential for

Overshooting Convection in Tropical Cyclones [PDF]
Geophysical Research Letters, 2010 Using infrared satellite imagery, best-track data, and reanalysis data, tropical cyclones are shown to contain a disproportionate amount of the deepest convection in the tropics.

No decrease of tropical convection in individual deep convective systems with global warming. [PDF]
NPJ Clim Atmos SciAccording to the scientific consensus, tropical convection must decrease with global warming. This decrease is manifested by a decrease of the mass transported in the upward branch of the atmospheric overturning circulation - the convective mass flux - and a connected decrease of high clouds in the tropics, with implications for climate sensitivity. By

More Intense, Organized Deep Convection With Shrinking Tropical Ascent Regions
Geophysical Research Letters, 2022 Changes in the frequency and morphology of convection in a warming climate have major implications for the hydrologic cycle and continue to be a large source of variability in climate models.

Impacts of fire emissions and transport pathways on the interannual variation of CO in the tropical upper troposphere [PDF]
Atmospheric Chemistry and Physics, 2014 This study investigates the impacts of fire emission, convection, various climate conditions and transport pathways on the interannual variation of carbon monoxide (CO) in the tropical upper troposphere (UT), by evaluating the field correlation between ...

Geographic and seasonal distributions of CO transport pathways and their roles in determining CO centers in the upper troposphere [PDF]
Atmospheric Chemistry and Physics, 2012 Past studies have identified a variety of pathways by which carbon monoxide (CO) may be transported from the surface to the tropical upper troposphere (UT); however, the relative roles that these transport pathways play in determining the distribution ...

Geophysical Research Letters, 2021 Convection is highly active on tropical islands. Based on a 3‐year radar climatology over Hainan Island, a mountainous tropical island in South China, we identified a distinct spatial dependence of convection initiation (CI) on the speed of the large ...

Balanced dynamics and convection in the tropical troposphere [PDF]
Journal of Advances in Modeling Earth Systems, 2015 AbstractThis paper presents a conceptual picture of balanced tropical tropospheric dynamics inspired by recent observations. The most important factor differentiating the tropics from middle and higher latitudes is the absence of baroclinic instability; upward motion occurs primarily via deep convective processes.
