Multiplicative MJO Forcing of ENSO

Journal of Climate, 2012
Abstract The Madden–Julian oscillation (MJO) is parameterized to study the role of the feedback it receives from sea surface temperature (SST) in its influence on El Niño–Southern Oscillation (ENSO). The parameterization describes MJO surface westerlies in terms of a few basic parameters that include amplitude, zonal propagation extent ...

ENSO regulation of MJO teleconnection

Climate Dynamics, 2010
The extratropical teleconnections associated with Madden–Julian Oscillation (MJO) are shown to have an action center in the North Pacific where the pressure anomalies have opposite polarities between the Phase 3 (convective Indian Ocean) and Phase 7 (convective western Pacific) of the MJO. The teleconnection in the same phase of MJO may induce opposite

The Experimental MJO Prediction Project

Bulletin of the American Meteorological Society, 2006
Weather prediction is typically concerned with lead times of hours to days, while seasonal-to-interannual climate prediction is concerned with lead times of months to seasons. Recently, there has been growing interest in 'subseasonal' forecasts---those that have lead times on the order of weeks (e.g., Schubert et al. 2002; Waliser et al.

Large-Scale Distinctions between MJO and Non-MJO Convective Initiation over the Tropical Indian Ocean

Journal of the Atmospheric Sciences, 2013
AbstractIn this study, the authors seek large-scale signals that may distinguish MJO from non-MJO convective events before they start over the Indian Ocean. Three such signals were found. Low-level easterly anomalies extend from the surface to the midtroposphere and move from the western to eastern Indian Ocean.

Probabilistic Predictability of the MJO

Journal of the Atmospheric Sciences
Abstract Studies of natural or intrinsic MJO predictability have typically estimated its limit at a fixed, single lead time. The interpretation of such a predictability limit has remained ambiguous. This study introduces a concept of probabilistic predictability, which defines MJO predictability in terms of the expected probability of

Further exploration of MJO initiation events and precursors as revealed by an MJO-like dynamical mode

2016
The Madden Julian Oscillation (MJO) is a tropical phenomenon that develops over the Indian Ocean as a large area of convection approximately 1000km across. This intraseasonal oscillation affects both weather and climate in extratropical regions, where most of the world's population resides.

The Impact of the MJO on Climate in Hawai‘i

Journal of Hydrometeorology
Abstract Among the most remote places on Earth, the Hawaiian Islands rely heavily on local water resources. Therefore, a deep understanding of rainfall variability is critical to ensure the habitability and sustainability of life on the archipelago.

Sources of S2S and MJO predictability

One main justification for subseasonal-to-seasonal (S2S) prediction is its identified sources of predictability. These sources include slowly varying phenomena, such as the MJO, stratospheric conditions, upper-ocean heat content, soil moisture, and sea ice.
