Moisture Decomposition With Normal Modes in Global Data: Balanced and Unbalanced Components

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Decompositions with normal modes have been useful for numerous purposes, such as theoretical understanding of balanced and unbalanced circulations, and applications to data assimilation. However, normal mode decompositions have typically been formulated for dry dynamics without moisture.

Tropical Pacific as a Pacemaker of Recent Decadal Anticyclonic Intensification Over the Barents–Kara Sea

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Under anthropogenic warming, a strengthened wintertime anticyclonic anomaly over the Barents–Kara Sea (BKS) has emerged as a hallmark of recent Arctic climate change. While local forcing from sea ice loss has been widely emphasized, the quantitative contribution of remote tropical forcing remains poorly constrained.

Track‐Dependent Links Between Tropical Cyclones and Extratropical Predictability in Physical and AI Models

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global medium‐range weather forecasts suffer occasional failures (“busts”) linked to tropical cyclones (TCs). We investigate TC influences on extratropical predictability by comparing forecasts from a physics‐based model (ECMWF‐IFS) and an AI‐hybrid model (Google‐NGCM) initialized near TC genesis.

Distinct Impacts of Western and Eastern Maritime Continent Convection on the South China Sea Tropical Cyclone Activity in Autumn

Geophysical Research Letters
Convection anomalies in the eastern and western Maritime Continent (MC) during boreal autumn exhibit distinct characteristics and climatic effects, but their impacts on South China Sea (SCS) tropical cyclones (TCs) remain unclear. Here we reveal that the

The Tropical Indo‐Pacific and North Atlantic Precursors for the Interannual Variation of Extreme Humid‐heat Days in the Yangtze River Basin

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Extreme humid‐heat events pose a major hazard across the Yangtze River Basin (YRB), yet their underlying mechanisms and seasonal predictability remain insufficiently understood. Here, using observational diagnostics and coupled model experiments, we identify three independent drivers in the tropical Indo‐Pacific and subtropical North Atlantic ...

Nonlinear Convection–SST Sensitivity as a Bridge for the Asymmetric Low‐Level Wind Response to ENSO

Geophysical Research Letters
Observations and model simulations reveal that El Niño generates stronger westerly anomalies than the easterlies induced by La Niña. Here we show that this asymmetry arises from the nonlinear sensitivity of atmospheric convection to total sea surface ...

Regulatory Factors of the Morning Peak of Summer Regional Precipitation Events Over the Middle and Lower Yangtze River Basin, China

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The diurnal variation of regional precipitation events (RPE) over the Middle and Lower Yangtze River Basin (MLYRB) significantly affects human activities and serves as a key reference for weather forecasting. Here, the diurnal variation of summer RPE over MLYRB under two monsoonal synoptic types and their regulatory factors have been addressed.

Mechanisms of the QBO Influence on the Tropical Troposphere: Modulation by ENSO Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is the dominant mode of tropical stratospheric variability that can influence tropospheric circulation and convection. El Niño‐Southern Oscillation (ENSO), which is the primary source of interannual variability in the tropical troposphere, can modulate both the QBO and its impact on the tropical troposphere.

Genotype‐Dependent Variations in Egg Quality and Nutritional Composition of Thermotolerant Chickens Under Hot‐Climate Conditions

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Hot‐climate conditions revealed clear genotype‐dependent differences in egg quality and nutritional composition among Fayoumi, Naked Neck, and Frizzled hens. These thermotolerant genotypes showed distinct amino acid, lipid, omega‐3, and iron profiles, supporting climate‐resilient poultry production.
