Factors influencing the meridional width of the equatorial deep jets [PDF]

Ocean Science, 2023
Equatorial deep jets (EDJs) are vertically alternating, stacked zonal currents that flow along the Equator in all three ocean basins at intermediate depth.

Intraseasonal variability in the Makassar Strait thermocline [PDF]

Journal of Marine Research, 2009
Intraseasonal variability [ISV] in the Makassar Strait thermocline is examined through the analysis of along-channel flow, regional sea level anomaly and wind fields from January 2004 through November 2006. The dominant variability of 45-90 day in the Makassar Strait along-channel flow is horizontally and vertically coherent and exhibits vertical ...

The intraseasonal variability of winter semester surface air temperature in Antarctica [PDF]

Polar Research, 2011
This study investigates systematically the intraseasonal variability of surface air temperature over Antarctica by applying empirical orthogonal function (EOF) analysis to the National Centers for Environmental Prediction, US Department of Energy ...

Influence of stratospheric sudden warming on the tropical intraseasonal convection

Environmental Research Letters, 2020
Madden–Julian oscillation (MJO), the dominant mode of intraseasonal variability in the tropical troposphere, has recently been shown to have a great impact on Northern Hemisphere (NH) extratropical stratosphere.

Intraseasonal Variability of Equatorial Indian Ocean Zonal Currents [PDF]

Journal of Climate, 2007
Abstract New satellite and in situ observations show large intraseasonal (10–60 day) variability of surface winds and upper-ocean current in the equatorial Indian Ocean, particularly in the east. An ocean model forced by the Quick Scatterometer (QuikSCAT) wind stress is used to study the dynamics of the intraseasonal zonal current.

Predictability Limit of Monsoon Intraseasonal Precipitation: An Implication of Central Indian Ocean Mode

Frontiers in Marine Science, 2022
The prediction of monsoonal precipitation during Indian summer monsoon (ISM) remains difficult. Due to the high correlation between the Central Indian Ocean (CIO) mode index and the ISM precipitation variability, the predictability limit of the CIO mode ...

Intraseasonal Rainfall Variability over Madagascar

Monthly Weather Review, 2016
Using daily rain gauge records for Madagascar and nearby islands, this paper investigates rainfall intraseasonal variability at local and regional scales during the austral summer season (November–February), as well as the respective influences of recurrent convective regimes over the southwest Indian Ocean (SWIO) and the Madden–Julian oscillation (MJO)

Intraseasonal variability of the West African monsoon [PDF]

Atmospheric Science Letters, 2011
AbstractThe intraseasonal time scale is critical in West Africa where resources are highly rainfall dependent. Three main modes of variability have been identified, two with a mean periodicity of 15 days and one with a mean periodicity around 40 days.

Origin of intraseasonal variability in Lake Tanganyika [PDF]

Geophysical Research Letters, 2002
Intraseasonal thermocline oscillations in Lake Tanganyika are analysed using observations near Mpulungu and simple analytical/numerical models, in order to understand their origin. The region around the lake is characterised by strong and persistent southeast winds during the four months dry season, lasting from May to August.

On the Relationship Between Tropical Instability Waves and Intraseasonal Equatorial Kelvin Waves in the Pacific From Satellite Observations (1993–2018)

Frontiers in Marine Science, 2022
Intraseasonal Kelvin waves (IKWs) and Tropical Instability Waves (TIWs) are essential components of the tropical Pacific coupled climate variability. While downwelling IKWs are precursors of ENSO (e.g., the El Niño Southern Oscillation), TIWs contribute ...
