End to end simulator for the WIVERN W-band Doppler conically scanning spaceborne radar [PDF]
, 2021 The WIVERN (WInd VElocity Radar Nephoscope) mission, soon entering in Phase-0 of the ESA Earth Explorer program, promises to complement Doppler wind lidar by globally observing, for the first time, vertical profiles of winds in cloudy areas.

Spatially Extended Tests of a Neural Network Parametrization Trained by Coarse-graining
, 2019 General circulation models (GCMs) typically have a grid size of 25--200 km. Parametrizations are used to represent diabatic processes such as radiative transfer and cloud microphysics and account for sub-grid-scale motions and variability.

Impact of microphysics on tropical precipitation extremes in a global storm-resolving model [PDF]
, 2021 The impact of microphysics on tropical precipitation extremes is explored with a global storm-resolving model by modifying the terminal velocity of raindrops. Depending on the time scales, precipitation extremes respond differently.

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...

Responses to Humidity and Temperature Perturbations in High‐Resolution Simulations of Convection
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.Abstract Convection parameterization is a leading source of uncertainty in global and regional climate models, and a lack of ground truth complicates the assessment of convection scheme performance. Here we test a linear framework for quantifying convective responses, using two models run at convection‐permitting resolution, to examine model responses ...

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.Abstract We compare three global kilometer‐scale models (ICON, IFS and NICAM) to clarify the advantages and challenges of high‐resolution global weather and climate modeling, using different approaches to represent convection, from fully parameterized to fully explicit.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Observations show a bimodal frequency distribution in total column vapor (TCV) over tropical oceans, with convective rainfall predominantly produced on the moist side of the frequency minimum between two modal peaks. Here we show a km–scale model of the tropics with explicit convection produces a bimodal TCV distribution, whereas the same ...
