Asymmetric intraseasonal events in the stochastic skeleton

چکیده
12 The stochastic skeleton model is a simpli ed model for the Madden-Julian oscil13 lation (MJO) and intraseasonal-planetary variability in general involving coupling of 14 planetary-scale dry dynamics, moisture, and a stochastic parametrization for the unre15 solved details of synoptic-scale activity. The model captures the fundamental features 16 of the MJO such as the intermittent growth and demise of MJO wave trains, the MJO 17 propagation speed, peculiar dispersion relation, quadrupole vortex structure, etc. We 18 analyze here the solutions of a stochastic skeleton model with an idealized seasonal 19 cycle, namely a background warm pool state of heating/moistening displacing merid20 ionally during the year. The present model considers both equatorial and o -equatorial 21

Boreal summer intraseasonal oscillations in the MJO skeleton model with observation-based forcing
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. In the current study, observation-based estimates of these forcing terms and background state are used. Linear sol...
متن کاملA Stochastic Skeleton Model for the MJO
The Madden–Julian oscillation (MJO) is the dominant mode of variability in the tropical atmosphere on intraseasonal time scales and planetary spatial scales. Despite the primary importance of the MJO and the decades of research progress since its original discovery, a generally accepted theory for its essential mechanisms has remained elusive. In recent work by two of the authors, a minimal dyn...
متن کاملA Suite of Skeleton Models for the MJO with Refined Vertical Structure
Abstract: TheMadden-Julian oscillation (MJO) is the dominantmode of variability in the tropical atmosphere on intraseasonal timescales and planetary spatial scales. The skeleton model is a minimal dynamical model that recovers robustly the most fundamental MJO features of (I) a slow eastward speed of roughly 5 ms−1, (II) a peculiar dispersion relation with dω/dk ≈ 0, and (III) a horizontal quad...

متن کاملNonlinear Dynamics and Regional Variations in the MJO Skeleton
A minimal, nonlinear oscillator model is analyzed for the Madden–Julian oscillation (MJO) ‘‘skeleton’’ (i.e., its fundamental features on intraseasonal/planetary scales), which includes the following: (i) a slow eastward phase speed of roughly 5 m s, (ii) a peculiar dispersion relation with dv/dk ’ 0, and (iii) a horizontal quadrupole vortex structure. Originally proposed in recent work by the ...
