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.

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.

Influence of Boreal Summer Intraseasonal Oscillation on Rainfall Extremes in the Philippines [PDF]

, 2021
This study investigates the impact of the northward/northwestward propagating 30–60-day mode of the boreal summer intraseasonal oscillation (BSISO) on the extreme rainfall events in the Philippines during the June–September (JJAS) season from 1979 to ...

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.

Development of Indian summer monsoon precipitation biases in two seasonal forecasting systems and their response to large-scale drivers [PDF]

Weather and Climate Dynamics
The Met Office Global Coupled Model (GC) and the National Centers for Environmental Prediction (NCEP) Climate Forecast System (CFSv2) are both widely used for predicting and simulating the Indian summer monsoon (ISM), and previous studies have ...

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 ...

Objective Classification of Asymmetric Modes of the Boreal Summer Intraseasonal Oscillation over the Western North Pacific and Their Divergent Impacts on Eastern China Precipitation

Atmosphere
The boreal summer intraseasonal oscillation (BSISO) over the western North Pacific (WNP) exhibits significant phase asymmetry, but a systematic classification of its asymmetric modes and their regional climatic impacts remains insufficiently explored ...

Development of the Boreal Summer Intraseasonal Oscillation Over the Western North Pacific Associated With Self‐Induced Fresh and Shallow Mixed Layers in 2024

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Air‐sea interaction plays an important role in the development of the boreal summer intraseasonal oscillation (BSISO). To elucidate this air‐sea interaction, a field observation using the research vessel (R/V) MIRAI was conducted in the tropical western North Pacific for 1 month in early summer 2024.

Dominant patterns of boreal summer interactions between tropics and mid-latitude: causal relationships and the role of timescales [PDF]

, 2020
Tropical convective activity represents a source of predictability for mid-latitude weather in the Northern Hemisphere. In winter, the El Niño–Southern Oscillation (ENSO) is the dominant source of predictability in the tropics and extra-tropics, but its ...

Mechanisms and Subseasonal Predictability of Unprecedented Multiple Tropical Cyclone Event in Autumn 2024

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract In autumn 2024 (late October to mid‐November), an unprecedented multiple tropical cyclone (MTC) event occurred over the western North Pacific (WNP). Six storms formed within a month, surpassing the climatological mean by 4 standard deviations. Four storms were simultaneously active—an event unmatched in 45 years.
