RISRoles of the Moisture and Wave Feedbacks in Shaping the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates the moisture and wave feedbacks in the Madden?Julian oscillation (MJO) dynamics by applying the general three-way interaction theoretical model. The three-way interaction model can reproduce ...
A Model for the Interaction between 2-Day Waves and Moist Kelvin Waves
Publisher: American Meteorological Society
Abstract: he eastward-propagating tropical low-frequency disturbances, such as the moist Kelvin waves or the Madden?Julian oscillation (MJO), are often observed to experience convective enhancement when meeting with the westward-propagating ...
An Air–Sea Coupled Skeleton Model for the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: his work is an extension and improvement of the minimal Madden?Julian oscillation (MJO) ?skeleton? model developed by Majda and Stechmann, which can capture some important features of the MJO?slow eastward propagation, ...
A Frictional Skeleton Model for the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: he Madden?Julian oscillation (MJO) is a multiscale system. A skeleton model, developed by Majda and Stechmann, can capture some of planetary-scale aspects of observed features such as slow eastward propagation, nondispersive ...
Mechanisms of Global Teleconnections Associated with the Asian Summer Monsoon: An Intermediate Model Analysis
Publisher: American Meteorological Society
Abstract: he Indian summer monsoon (ISM) and western North Pacific summer monsoon (WNPSM) are two subsystems of the Asian summer monsoon, and they exhibit different global teleconnection patterns. The enhanced ISM strengthens the ...
A Mechanism for Explaining the Maximum Intraseasonal Oscillation Center over the Western North Pacific
Publisher: American Meteorological Society
Abstract: uring late boreal summer (July?October), the intraseasonal oscillation (ISO) exhibits maximum variability over the western North Pacific (WNP) centered in the South China Sea and Philippine Sea, but many numerical models ...
A Model for Scale Interaction in the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: he Madden?Julian oscillation (MJO) is an equatorial planetary-scale circulation system coupled with a multiscale convective complex, and it moves eastward slowly (about 5 m s?1) with a horizontal quadrupole vortex and ...
Factors Regulating the Multidecadal Changes in MJO Amplitude over the Twentieth Century
Publisher: American Meteorological Society
Abstract: This study examined multidecadal changes in the amplitude of the boreal-winter Madden–Julian oscillation (MJO) over the twentieth century using two century-long reanalysis datasets (20CR and ERA-20C). Both revealed reasonable ...
Roles of Barotropic Convective Momentum Transport in the Intraseasonal Oscillation
Publisher: American Meteorological Society
Abstract: oth observational data analysis and model simulations suggest that convective momentum transport (CMT) by cumulus convection may play a significant role in the intraseasonal oscillations (ISO) by redistributing atmospheric ...
Observer Based H∠Control on Nonhomogeneous Discrete Time Markov Jump Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concerns the problem of observerbased H∠controller design for a class of discretetime Markov jump systems with nonhomogeneous jump parameters. A nonhomogeneous jump transition probability matrix is described ...
