Intraseasonal Variability of Air Temperature Over East Asia in Boreal Summer

Frontiers in Earth Science, 2017
The intraseasonal oscillation (ISO) of atmospheric temperature at 2 m over East Asia (EA) in boreal summer is investigated through NCEP-NCAR reanalysis data for the period of 1979–2013.

Data-Driven Global Subseasonal Forecast for Intraseasonal Oscillation Components

Atmosphere, 2023
As a challenge in the construction of a “seamless forecast” system, improving the prediction skills of subseasonal forecasts is a key issue for meteorologists.

Influence of the Madden-Julian Oscillation on upper tropospheric humidity [PDF]

, 2002
Variations of upper tropospheric humidity (UTH) and cold cloud in the tropics reveal coherent changes that propagate eastward from the Indian Ocean into the Pacific. The coherence of UTH is high at periods of 30–90 days along the equator.

A retrospective on the 2025 Atlantic hurricane season

Weather, EarlyView.
The 2025 Atlantic hurricane season was intermittent, with extended quiet periods separated by three clusters of activity. The broad‐scale conditions were often unfavourable for cyclogenesis and common drivers of activity such as La Niña were weak, but well above‐average sea temperatures still supported intense storms.

A dynamical framework for the origin of the diagonal South Pacific and South Atlantic convergence zones [PDF]

, 2015
The South Pacific Convergence Zone (SPCZ) and South Atlantic Convergence Zone (SACZ) are diagonal bands of precipitation that extend from the equator southeastward into the Southern Hemisphere over the western Pacific and Atlantic Oceans, respectively ...

Tropical–Extratropical Interactions of Intraseasonal Oscillations

Journal of the Atmospheric Sciences, 2013
Abstract Tropical–extratropical interactions of intraseasonal oscillations (ISOs), based on 30 years (1979–2009) of northern winter observations and theory, are compared. The phase relationships between the tropical signal of the leading theoretical ISO for a January 1979 basic state and the development of Pacific–North America (PNA ...

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Fast and slow Kelvin waves in the Madden-Julian Oscillation of a GCM [PDF]

, 1999
The structure of the Madden-Julian Oscillation (MJO) in an 1800-day integration of the Hadley Centre Unified Model was analysed, and interpreted within a Kelvin wave framework. The model was forced with constant equinoctial (March) boundary conditions so

Mechanisms of some tropical intraseasonal oscillations

Geophysical Research Letters, 1992
A underlying mechanism for two westward propagating tropical intraseasonal oscillations is discovered. Destabilization of equatorial normal modes by moist feedbacks, in particular, by evaporation‐wind feedback, is responsible for both of them. The westward propagating 4–5 day oscillation and the quasi‐biweekly oscillation result from destabilization of
