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, 2009 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. Although tropical cyclones account for only 7% of the deep convection in the tropics, they account for about 15% of the deep convection with cloud‐top temperatures below the ...

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 ...

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 ...

Mesoscale convective clustering enhances tropical precipitation
Science Advances, 2023 In the tropics, extreme precipitation events are often caused by mesoscale systems of organized, spatially clustered deep cumulonimbi, posing a substantial risk to life and property. While the clustering of convective clouds has been thought to strengthen precipitation rate, no quantitative estimates of this hypothesized enhancement exist.

Influence of the Madden‐Julian Oscillation on Continental United States Hurricane Landfalls
Geophysical Research Letters, 2023 The Madden‐Julian oscillation (MJO) significantly impacts North Atlantic hurricanes, with increased hurricane activity occurring when the MJO enhances convection over Africa and the tropical Indian Ocean and suppressed hurricane activity occurring when ...

Remote Sensing, 2022 The East Asian winter monsoon (EAWM) is the most important climate system for transporting Arctic cold air to the tropics in boreal winter. Rapid intensification of the EAWM, such as a cold surge, can lead to increased tropical convection over the ...

The Combined QBO and ENSO Influence on Tropical Cyclone Activity over the North Atlantic Ocean
Atmosphere, 2021 The Quasi-Biennal Oscillation (QBO) and the El Niño-Southern Oscillation (ENSO) largely modulate the zonal wind in the tropics. Previous studies showed that QBO phases produce changes in deep convection through an increase/decrease in the tropopause ...

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.
