    The JWST MIRI transmission spectrum of WASP-107b, a transiting planet with Neptune-like mass and Jupiter-like radius, shows observations of sulfur dioxide and silicate clouds but no methane in its atmosphere, providing evidence of disequilibrium chemistry and active photochemistry.

    Analysis of transits of an ultra-hot giant exoplanet reports the precise abundance constraints of 14 major refractory elements, showing distinct deviations from proto-solar, along with a sharp transition temperature at which those elements are depleted.

    The dayside thermal emission spectrum and brightness temperature map of the ultra-hot Jupiter WASP-18b obtained from the NIRISS instrument on the JWST showed water emission features, an atmosphere consistent with solar metallicity, as well as a steep and symmetrical decrease in temperature towards the nightside.

    Analysis of sea-level pressure measurements shows that, in agreement with the latest suite of climate models, the Hadley circulation has considerably weakened in the Northern Hemisphere over recent decades, driven by anthropogenic emissions.

    Weakening blocking effect of the High Mountain Asia on the westerlies-carried deficit in precipitation minus evaporation from the southeast North Atlantic is demonstrated, leading to persistent northward expansion of terrestrial water storage deficit in the Tibet Plateau.

    Analysis of new observations from the EUREC4A field campaign shows that lower-tropospheric mixing does not desiccate the base of trade cumulus clouds, refuting the mixing-desiccation hypothesis and explaining the weak trade cumulus feedback.

    The Pacific cold tongue is shown to possess two distinct annual cycles with complex interference effects, calling for a reassessment of its seasonal dynamics and re-evaluation of tropical Pacific palaeoclimate records of annual cycle phase changes.

    The core North American monsoon arises through topographic steering of the jet stream, and should be considered as convection-enhanced orographic rainfall produced by a mechanically forced stationary wave.

    Cloud-top thermal images obtained by the Akatsuki orbiter show that Venus has almost null mean meridional circulation at the cloud top, because poleward circulation on the dayside is offset by equatorward circulation on the nightside.

    Atmospheric concentration measurements at remote sites around the world reveal an accelerated decline in the global mean CFC-11 concentration during 2018 and 2019, reversing recent trends and building confidence in the timely recovery of the stratospheric ozone layer.

    North Atlantic landfalling hurricanes are weakening more slowly than in the past because warming oceans are increasing the moisture carried by the storm until it hits land, and this storm moisture acts as an ongoing heat source post-landfall.

    Current models are too noisy to predict climate usefully on decadal timescales, but two-stage post-processing of model outputs greatly improves predictions of decadal variations in North Atlantic winter climate.

    Radio interferometric observations of lightning over the Netherlands reveal small needle-shaped plasma structures associated with the positive leader channels, explaining why cloud-to-ground lightning connects to the ground multiple times.

    Our current understanding of the spatio-temporal complexity of the El Niño–Southern Oscillation phenomenon is reviewed and a unifying framework that identifies the key factors for this complexity is proposed.

    Observations of broadband emission from lightning on Jupiter at 600 megahertz show a lightning discharge mechanism similar to that of terrestrial lightning and indicate increased moist convection near Jupiter’s poles.

    The determination of Jupiter’s even gravitational moments by the Juno spacecraft reveals that more than three thousand kilometres below the cloud tops, differential rotation is suppressed and the gas giant’s interior rotates as a solid body.

    Visible and infrared images obtained from above each pole of Jupiter by the Juno spacecraft reveal polygonal patterns of large cyclones; it is unknown how these cyclones evolved, or how they persist without merging.

    The upper atmosphere above Jupiter’s Great Red Spot—the largest storm in the Solar System—is hundreds of degrees hotter than anywhere else on the planet; the heating must come from below, suggesting coupling between Jupiter’s lower and upper atmospheres, probably the result of upwardly propagating acoustic or gravity waves.

    Satellite records show that the global pattern of cloud changes between the 1980s and the 2000s are similar to the patterns predicted by models of climate with recent external radiative forcing, and that the primary drivers of the cloud changes appear to be increasing greenhouse gas concentrations and a recovery from volcanic radiative cooling.

    Spectroscopic detection and characterization of an irradiated substellar donor planet in an accreting white-dwarf binary system reveals a donor mass of 0.055 ± 0.008 solar masses, an average spectral type of L1 ± 1 and an average irradiation-induced temperature difference between the dayside and nightside of 57 kelvin.
