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.

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 ...

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.

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.

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 ...

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.

Evolution of convection during tropical cyclogenesis [PDF]
Geophysical Research Letters, 2007 Central to tropical cyclogenesis is the changing behavior of moist convection as the cyclone evolves. Based on a cumulus ensemble model run in weak temperature gradient mode, we suggest that the mid‐level vortex created by early‐stage convection stabilizes the environment in way that favors further development.

The effect of deep, tropical convection on the tropical tropopause layer [PDF]
Journal of Geophysical Research, 2002 There is evidence that most detrainment from tropical convection occurs below ∼14 km, about 2 km below the tropopause. On the other hand, it is also generally accepted that convection does occasionally reach the altitude of the tropopause. The question is whether the relatively infrequent penetrations above 14 km are sufficient to influence the ...

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 ...
