RISObserved Structure of Convectively Coupled Waves as a Function of Equivalent Depth: Kelvin Waves and the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: he view that convectively coupled Kelvin waves and the Madden?Julian oscillation (MJO) are distinct modes is tested by regressing data from the Climate Forecast System Reanalysis against satellite outgoing longwave radiation ...
The Spectrum of Convectively Coupled Kelvin Waves and the Madden–Julian Oscillation in Regions of Low-Level Easterly and Westerly Background Flow
Publisher: American Meteorological Society
Abstract: he zonal wavenumber?frequency power spectrum of outgoing longwave radiation in the global tropics suggests that power in convectively coupled Kelvin waves and the Madden?Julian oscillation (MJO) is organized into two ...
Regression Analysis of Zonally Narrow Components of the MJO
Publisher: American Meteorological Society
Abstract: ecent works have demonstrated that eastward-propagating features smaller than zonal wavenumber 3 but with spatial structures similar to those of the Madden?Julian oscillation (MJO) frequently develop over the Indo-Pacific ...
Some Aspects of Western Hemisphere Circulation and the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: lthough the greatest variance in convection associated with the Madden?Julian oscillation (MJO) occurs over the Indo-Pacific warm pool, the MJO is associated with substantial circulation patterns in the tropics and the ...
Analysis of Convectively Coupled Kelvin Waves in the Indian Ocean MJO
Publisher: American Meteorological Society
Abstract: The active convective phase of the Madden?Julian oscillation (hereafter active MJO) comprises enhanced moist deep convection on its own temporal and spatial scales as well as increased variance in convection associated ...
On the Interpretation of EOF Analysis of ENSO, Atmospheric Kelvin Waves, and the MJO
Publisher: American Meteorological Society
Abstract: mpirical orthogonal function (EOF) analysis is frequently applied to derive patterns and indexes used to identify and track weather and climate modes as expressed in state variables or proxies of convection. Individual ...
Interaction with the Extratropics as a New Hypothesis for the Spectral Peak of the Madden–Julian Oscillation
Publisher: American Meteorological Society
The Development of Upper-Tropospheric Wind over the Western Hemisphere in Association with MJO Convective Initiation
Publisher: American Meteorological Society
Abstract: his study examines the structure and driving mechanisms of upper-tropospheric intraseasonal zonal wind anomalies over the Western Hemisphere (WH) during the convective initiation of the Madden?Julian oscillation (MJO) over ...
The Compressional Beta Effect: Analytical Solution, Numerical Benchmark, and Data Analysis
Publisher: American Meteorological Society
Abstract: This study derives a complete set of equatorially confined wave solutions from an anelastic equation set with the complete Coriolis terms, which include both the vertical and meridional planetary vorticity. The propagation ...
The Role of Interactions between Multiscale Circulations on the Observed Zonally Averaged Zonal Wind Variability Associated with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: he mechanisms driving the upper-tropospheric zonal mean intraseasonal zonal wind associated with the Madden?Julian oscillation are examined through budget analysis during boreal winter. To diagnose the role of nonlinear ...
