Is precipitation a good metric for model performance?
Precipitation has often been used to gauge the performances of numerical weather and
climate models, sometimes together with other variables such as temperature, humidity …

Tropical Pacific SST and ITCZ biases in climate models: Double trouble for future rainfall projections?
Abstract The double Intertropical Convergence Zone bias remains a persistent problem in
coupled general circulation model simulations. Due to the strong sea surface temperature …

Contrasting recent and future ITCZ changes from distinct tropical warming patterns
This study synthesizes the observed trends and projected changes in the Intertropical
Convergence Zones (ITCZs). Under future warming, the seasonal ITCZs are projected to …

Double and single ITCZs with and without clouds
A major bias in tropical precipitation over the Pacific in climate simulations stems from the
models' tendency to produce two strong distinct intertropical convergence zones (ITCZs) too …

Controls on the width of tropical precipitation and its contraction under global warming
Climate models robustly and unanimously simulate narrowing of the intense tropical
precipitation under greenhouse gas forcing. We argue that the meridional width of tropical …

Control of ITCZ width by low‐level radiative heating from upper‐level clouds in aquaplanet simulations
Atmospheric cloud radiative effects (ACRE) narrow the Intertropical Convergence Zones
(ITCZs) in climate models. Some studies have attributed this to the upper tropospheric …

Modality of the tropical rain belt across models and simulated climates
The tropical rain belt varies between unimodal and bimodal meridional precipitation
distributions, both regionally and on seasonal to geological time scales. Here we show that …

Stronger zonal convective clustering associated with a wider tropical rain belt
M Popp, S Bony - Nature communications, 2019 - nature.com
Deep convection can exhibit a large diversity of spatial organizations along the equator. The
form of organization may affect the tropical large-scale motions of the atmosphere, but …

Reduced tropical climate land area under global warming
Regions along the edges of the tropics host vast populations and ecosystems which are
sensitive to climate change. Here we examine the extent of tropical land areas in the ERA5 …
