Madden-julian Oscillation
[1] The Madden-Julian Oscillation (MJO) is the dominant component of the intraseasonal (30–90 days) variability in the tropical atmosphere. It consists of large-scale coupled patterns in atmospheric circulation and deep convection, with coherent signals in many other variables, all propagating eastward slowly ( 5 m s ) through the portion of the Indian and Pacific oceans where the sea surface i...
متن کاملMoisture Modes and the Madden-Julian Oscillation
Moisture mode instability is thought to occur in the tropical oceanic atmosphere when precipitation is a strongly increasing function of saturation fraction (precipitable water divided by saturated precipitable water) and when convection acts to increase the saturation fraction. A highly simpli ed model of the interaction between convection and large-scale ows in the tropics suggests that there...
متن کاملThe Madden Julian Oscillation A Literature Review
The literature survey reviews our present understanding of the Madden Julian Oscillation. This perturbation to the circulation of the tropical atmosphere involves anomalies in climate elements such as pressure, wind, outgoing long wave radiation, and temperature. It is successfully simulated by the present generation of general climate and atmospheric general circulation models. The literature ...
متن کاملPropagating versus Nonpropagating Madden–Julian Oscillation Events
Basinwide convective anomalies over the IndianOcean (IO) associated with theMadden–Julian oscillation (MJO) sometimes propagate eastward and reach the west Pacific (WP), but sometimes do not. Long-term observations and reanalysis products are used to investigate the difference between the propagating and nonpropagating MJO events. IO convection onset events associated with the MJO are grouped i...
متن کاملStructure and Properties of Madden–Julian Oscillations Deduced from DYNAMO Sounding Arrays
The kinematic and thermodynamic characteristics of the October and November 2011 Madden–Julian oscillations (MJOs) that occurred over the Indian Ocean during Dynamics of the MJO (DYNAMO) are investigated. Analyses are presented 1) for two primary sounding arrays, where results are independent of model parameterizations, and 2) on larger scales, including the Indian Ocean, using operational and ...
