A Climatology of Mesoscale Convective System Hazards in the United States and Their Representation in a Convection‐Permitting Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Mesoscale convective systems (MCSs) are large, organized convective storms that frequently produce flash floods and other severe hazards such as damaging winds, hail, and tornadoes. Developing an observationally based MCS hazard climatology is important for establishing a baseline to evaluate the representation of these events in numerical ...

Physical‐Background‐Constrained Bias Correction for Daily Precipitation Prediction Over China by a Subseasonal‐to‐Seasonal Model

Atmospheric Science Letters, Volume 27, Issue 3, March 2026.
The prediction skill of the CMA‐CPSv3 model beyond 15 days is hindered by both its systematic bias and its incapability in capturing the modulations of predictability sources. The regional‐aggregation‐based QM method can largely overcome the overfitting problem, eliminating the model bias that overestimates drizzle precipitation and underestimates ...

Evaluation of Global Storm‐Resolving Models in DYAMOND‐Winter: Radiation, Precipitation, Water Vapor, and Convective Organization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract We present a comprehensive evaluation of 13 global storm‐resolving models participating in the DYnamics of the Atmospheric general circulation Modeled On Non‐hydrostatic Domains (DYAMOND) Winter intercomparison project, focusing on their ability to simulate key atmospheric fields, such as precipitation rate, outgoing longwave radiation, and ...

Precipitation Characteristics and Thermodynamic‐Convection Coupling in Global Kilometer‐Scale Simulations

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.

An Idealized Two‐Dimensional Atmospheric Model of the Quasi‐Biennial Oscillation and Wave‐Mean Flow Interactions in the Equatorial Channel

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract The quasi‐biennial oscillation (QBO) is a fundamental mode of atmospheric variability and a textbook example of wave‐mean flow interactions. While its general theory has been established about 50 years ago by the seminal works of Holton, Lindzen and Plumb (HLP), it remains an unsettled problem of geophysical fluid dynamics and a challenge for ...

Accurate Column Moist Static Energy Budget in Climate Models. Part 1: Conservation Equation Formulation, Methodology, and Primary Results Demonstrated Using GISS ModelE3

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Column‐integrated moist static energy (MSE) budgets underpin theories of tropical convection and circulation, yet in reanalyses and climate models the budget rarely closes; residuals routinely match the leading terms and mask physical insights.

Indonesian Throughflow promoted eastward propagation of the Madden-Julian Oscillation

npj Climate and Atmospheric Science
Understanding the impacts of the Indonesian Throughflow (ITF) on the eastward propagation of the Madden-Julian Oscillation (MJO) is crucial for accurately simulating the MJO and achieving high-skill sub-seasonal predictions.

Barrier Effect of the Indo-Pacific Maritime Continent on the MJO: Perspectives from Tracking MJO Precipitation

Journal of Climate, 2017
Explanations for the barrier effect of the Indo-Pacific Maritime Continent (MC) on the MJO should satisfy two criteria. First, they should include specific features of the MC, namely, its intricate land–sea distributions and elevated terrains. Second, they should include mechanisms for both the barrier effect and its overcoming by some MJO events ...

Systematic Benchmarking of Climate Models: Methodologies, Applications, and New Directions

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract As climate models become increasingly complex, there is a growing need to comprehensively and systematically assess model performance with respect to observations. Given the increasing number and diversity of climate model simulations in use, the community has moved beyond simple model intercomparison and toward developing methods capable of ...

Benchmarking Atmospheric Circulation Variability in an AI Emulator, ACE2, and a Hybrid Model, NeuralGCM

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Physics‐based atmosphere‐land models with prescribed sea surface temperature have notable successes but also biases in their ability to represent atmospheric variability compared to observations. Recently, AI emulators and hybrid models have emerged with the potential to overcome these biases, but still require systematic evaluation against ...
