The impact of atmospheric Rossby waves and cyclones on the Arctic sea ice variability
The Arctic sea-ice extent has strongly declined over recent decades. A large inter-annual variability is superimposed on this negative trend....

Observed surface and subsurface Marine Heat Waves in the Bay of Bengal from in-situ and high-resolution satellite data
Marine Heat Waves (MHWs) can cause significant distress to marine environment and modulate air-sea interaction, which in turn can have economic and...

How the central-western equatorial Pacific easterly wind in early 2022 affects the third-year La Niña occurrence
After consecutive two years with the La Niña phenomenon in 2020–2021, cold sea surface temperature (SST) anomalies in the central-eastern equatorial...

Intraseasonal variability of subsurface ocean temperature anomalies in the Indian Ocean during the summer monsoon season
The present study focuses on the variability of subsurface ocean temperature and associated planetary waves (oceanic Kelvin and Rossby waves) in the...

An overlooked aspect concerning the effect of the spatial pattern of zonal wind stress anomalies on El Niño evolution and diversity
Anomalous zonal wind stress in the central-to-western Pacific plays a crucial role in ENSO evolution by exciting oceanic waves that propagate...

Role of the eastern boundary-generated waves on the termination of 1997 Indian Ocean Dipole event
The termination of Indian Ocean Dipole (IOD) events is examined in terms of equatorial wave dynamics. In situ and satellite observations combined...

Beams and Undercurrents
The complete solutions to the LCS model are superpositions of the responses to many modes. In these solutions and for periodic forcing, wave energy...

Influence of the extreme Indian Ocean dipole 2019 on the equatorial Indian Ocean circulation
This study examines direct current measurements in the central equatorial Indian Ocean during the positive phase of the extreme Indian Ocean Dipole...

Sea surface temperature anomaly of Southwest Pacific dipole in boreal Winter–Spring: a mechanism for the Indian Ocean Dipole
The formation mechanisms of the Indian Ocean Dipole (IOD) have been studied extensively. However, few studies have considered the influence of the...

Diurnal coastal trapped waves propagating along the east coast of the Shimokita Peninsula, Japan
In this study, we investigated diurnal coastal trapped waves in the eastern coastal area of the Shimokita Peninsula near the Tsugaru Strait. The...

Extreme IOD induced tropical Indian Ocean warming in 2020
The tropical Indian Ocean (TIO) basin-wide warming occurred in 2020, following an extreme positive Indian Ocean Dipole (IOD) event instead of an El...

Where the winds clash: what is really triggering El Niño initiation?
El Niño–Southern Oscillation (ENSO) is the Earth’s strongest source of year-to-year climate variability, whose center of action, although being in...

Abrupt increase in Greenland melt enhanced by atmospheric wave changes
Recent Greenland ice-sheet melt constitutes a considerable contribution to global sea-level rise. Observations indicate an approximate zero mass...

Suppressed Upwelling Events in the Seychelles–Chagos Thermocline Ridge of the Southwestern Tropical Indian Ocean
A prominent subsurface upwelling over the Seychelles–Chagos Thermocline Ridge (SCTR) in the southwestern tropical Indian Ocean is suppressed when...

Current observation and analysis based on mooring systems in the Andaman Sea
The basic structure and intraseasonal evolution of currents in the southeastern Andaman Sea was analyzed based on data collected in 2017 from two...

Equatorial Ocean: Switched-On Forcing
Near-equatorial solutions forced by switched-on winds are found to a simplified version of the LCS equations that neglects the acceleration and...

The 2021 Atlantic Niño and Benguela Niño Events: external forcings and air–sea interactions
This paper presents a comprehensive analysis of the extreme Atlantic and Benguela Niño events that occurred during the boreal spring–summer of 2021....

Distinctive characteristics and dynamics of the summer and autumn Indian ocean dipole events
The Indian Ocean Dipole (IOD) with worldwide socio-economic impacts has been presented to mature either in boreal summer or autumn, leading to the...

Oceanic impacts on 50–80-day intraseasonal oscillation in the eastern tropical Indian Ocean
In this study, daily outgoing longwave radiation (OLR) product is used to detect the atmospheric intraseasonal oscillation (ISO) in the eastern...
