The characteristics of squall lines in the Southeast Asia region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Squall lines over the Maritime Continent were analysed using 20 years of IMERG GPM data and classified into four regional clusters. Significant regional differences were found in their size, intensity, lifespan, and propagation. Nighttime squall lines are primarily driven by the convergence of opposing offshore flows and the convergence of monsoonal ...

Distinct Dominant Intraseasonal Oscillation Modes Modulate South China's Persistent Extreme Precipitation in Rainy Season

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract This study investigates mechanisms by which distinct intraseasonal oscillation modes drive regional persistent extreme precipitation events over South China during the rainy season. Based on periodic characteristics of 54 such events, two dominant modes are identified: 12–20‐day (type‐1) and 25–50‐day (type‐2) oscillations. Although comparable

Indo–Western Pacific Tropical Heating Anomalies Regulate the Cross‐Pacific Atmospheric River Highways During Boreal Summer

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Atmospheric rivers (ARs) constitute a global, interconnected highway network rather than isolated regional events. In boreal summer, cross‐Pacific ARs originate over Southeast Asia, are fueled by subtropical outflows from the Asian monsoon plume, transport warm, moist air across the North Pacific, and make landfall in North America (NA).

Limited Influence of Pre‐Existing Tropical Cyclones on Subsequent Cyclogenesis in the Western North Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Previous studies suggest that a tropical cyclone (TC) may contribute to the genesis of another TC to its east or southeast in the western North Pacific (WNP) through Rossby wave dispersion. However, the influence of a pre‐existing TC (PTC) has not been fully clarified in realistic simulations.

Equatorial convection controls boreal summer intraseasonal oscillations in the present and future climates

npj Climate and Atmospheric Science
The boreal summer intraseasonal oscillation (BSISO) is the major mode of tropical intraseasonal variability during the Indian summer monsoon (ISM), it partly controls the dry and wet spells of the ISM and thus is crucial for agricultural yield in the ...

Multiscale Interactions between Local Short- and Long-Term Spatio-Temporal Mechanisms and Their Impact on California Wildfire Dynamics

Fire
California has experienced a surge in wildfires, prompting research into contributing factors, including weather and climate conditions. This study investigates the complex, multiscale interactions between large-scale climate patterns, such as the Boreal

Modal Interference Drives Madden‐Julian Oscillation Evolution and Predictability

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract A data‐driven dynamical filter is developed to characterize Madden‐Julian Oscillation (MJO) variability, by representing tropical variability with nonorthogonal empirical‐dynamical modes that allow for constructive and destructive interference.

Joint modulation of coastal rainfall in Northeast Australia by local and large‐scale forcings

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
Spatially heterogeneous rainfall patterns over the coastal regions of northern Queensland are consistent between radar observations and model simulations. Rainfall propagation modulates the average rainfall distribution, leading to inhomogeneous rainfall patterns along the coast.

Stratospheric Quasi‐Biennial Oscillation Modulates the Impact of Boreal Summer Intraseasonal Oscillation on Rainfall Extremes in the Yangtze–Huaihe River Basin

Geophysical Research Letters
The impact of the boreal summer intraseasonal oscillation (BSISO) on rainfall anomalies in the Yangtze–Huaihe River Basin (YHRB) was found to be modulated by the stratospheric quasi‐biennial oscillation (QBO), which is reasonable for the close ...

Variability in Updraft Mass Flux Across the Top of the Atmospheric Boundary Layer Over the Tropical Western North Pacific Associated With a Tropical Depression

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract Over tropical oceans, cumulus convection is triggered by updrafts from the atmospheric boundary layer (BL). Given mutual interactions between cumulus convective ensembles and synoptic‐ to global‐scale atmospheric phenomena, it seems important to quantitatively evaluate the updraft on spatiotemporal scales relevant to the interactions and ...
