Seasonality of the intraseasonal variability in the upper equatorial western Pacific Ocean currents

Environmental Research Letters
Quantifying spatiotemporal characteristics of intraseasonal variability (ISV) of upper ocean (100 m) zonal currents ( U ) in the equatorial western Pacific remains difficult due to a lack of direct observations. Here we investigate the characteristics by

Oceanic factors controlling the Indian summer monsoon onset in a coupled model [PDF]

, 2014
International audienceDespite huge socio-economical impacts, the predictability of the Indian summer monsoon (ISM) onset remains drastically limited by the inability of both current forced and coupled models to reproduce a realistic monsoon seasonal ...

Diagnosing ocean feedbacks to the MJO: SST-modulated surface fluxes and the moist static energy budget [PDF]

, 2016
The composite effect of intraseasonal sea surface temperature (SST) variability on the Madden-Julian Oscillation (MJO) is studied in the context of the column integrated moist static energy (MSE) budget using data from the European Centre for Medium ...

Boreal summer intraseasonal oscillations in the MJO skeleton model with observation-based forcing

Dynamics of Atmospheres and Oceans, 2017
Abstract The Madden-Julian oscillation (MJO) skeleton model is a low-order model for intraseasonal oscillations that, in an extended form, includes off-equatorial and antisymmetric components. Previous studies of this extended model have used an idealized background state and forcing terms.

Vertical structure and physical processes of the Madden-Julian oscillation: Linking hindcast fidelity to simulated diabatic heating and moistening [PDF]

, 2015
Many theories for the Madden-Julian oscillation (MJO) focus on diabatic processes, particularly the evolution of vertical heating and moistening. Poor MJO performance in weather and climate models is often blamed on biases in these processes and their ...

Enhanced Pacific Northwest heat extremes and wildfire risks induced by the boreal summer intraseasonal oscillation

npj Climate and Atmospheric Science
The occurrence of extreme hot and dry summer conditions in the Pacific Northwest region of North America (PNW) has been known to be influenced by climate modes of variability such as the El Niño-Southern Oscillation and other variations in tropospheric ...

The role of the basic state in the ENSO-monsoon relationship and implications for predictability [PDF]

, 2005
The impact of systematic model errors on a coupled simulation of the Asian Summer monsoon and its interannual variability is studied. Although the mean monsoon climate is reasonably well captured, systematic errors in the equatorial Pacific mean that the

Dependence of Simulation of Boreal Summer Tropical Intraseasonal Oscillations on the Simulation of Seasonal Mean

Journal of the Atmospheric Sciences, 2007
Abstract The link between realism in simulation of the seasonal mean precipitation and summer tropical intraseasonal oscillations and their dependence on cumulus parameterization schemes is investigated using the Florida State University Global Spectral Model (FSUGSM).
