Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

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 ...

Estimating High Spatio-Temporal Resolution Rainfall from MSG1 and GPM IMERG Based on Machine Learning: Case Study of Iran

Remote Sensing, 2019
A new satellite-based technique for rainfall retrieval in high spatio-temporal resolution (3 km, 15 min) for Iran is presented. The algorithm is based on the infrared bands of the Meteosat Second Generation Spinning Enhanced Visible and Infrared Imager ...

Precipitation‐Buoyancy Relationships in the Life Cycle of Tropical Mesoscale Convective Systems

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study aims to establish process‐level benchmarks linking Mesoscale Convective Systems (MCSs) at various stages of their life cycle to their thermodynamic environment. The relationship between MCS precipitation and an empirical buoyancy measure (BL ${\mathrm{B}}_{L}$) is examined using collocated satellite‐observed MCS tracks and ...

A multi-satellite climatology of clouds, radiation and precipitation in southern West Africa and comparison to climate models [PDF]

, 2016
Southern West Africa (SWA) has a large population that relies on highly variable monsoon rainfall, yet climate models show little consensus over projected precipitation in this region.

An Optimized Parameterization of Sub‐Grid Scale Advection for Convection Permitting Models

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Convection‐permitting models (CPMs) explicitly resolve deep convection yet under‐resolve the organized lateral exchanges among drafts and their environment that control entrainment/detrainment, precipitation efficiency, and mesoscale structure.

Urban Rainfall Island Detection Remains Uncertain: A Global Sensitivity Analysis Across Data Sets and Methods

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Urbanization can enhance local precipitation through thermodynamic and dynamic effects, yet detection of the urban rainfall island (URI) effect remains uncertain at the global scale because results vary across data sets, methods, and spatiotemporal resolutions.

The Untapped Hydropower Potential of World's Cities

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Many large cities around the world experience frequent power outages and yet have an abundance of tall buildings and experience rainfall. This represents a unique and scalable opportunity for cities to capture the intermittent rainwater at high elevation and convert the potential energy into electricity for rechargeable batteries at street ...
