RISA New Perspective on the Excitation of Low-Tropospheric Mixed Rossby–Gravity Waves in Association with Energy Dispersion
Publisher: American Meteorological Society
Abstract: his study investigates the synoptic-scale equatorial response to Rossby wave energy dispersion associated with off-equatorial wave activity sources and proposes a new mechanism for triggering low-level mixed Rossby?gravity ...
The Origin and Dispersion Characteristics of the Observed Tropical Summertime Synoptic-Scale Waves over the Western Pacific
Publisher: American Meteorological Society
Abstract: The origin, initiation, and dispersion behavior of the observed summertime synoptic-scale disturbances in the tropical western Pacific are studied. These westward-propagating disturbances have the strongest growth rate ...
The Impact of ENSO on Atmospheric Intraseasonal Variability as Inferred from Observations and GCM Simulations
Publisher: American Meteorological Society
Abstract: The impact of the El Niño?Southern Oscillation (ENSO) on the atmospheric intraseasonal variability in the North Pacific is assessed, with emphasis on how ENSO modulates midlatitude circulation anomalies associated with the ...
Improving the Northeast Asian Monsoon Simulation: Remote Impact of Tropical Heating Bias Correction
Publisher: American Meteorological Society
Abstract: This study investigates the role of model tropical diabatic heating error on the boreal summer northeast Asian monsoon (NEAM) simulation given by a general circulation model (GCM). A numerical experiment is carried out in ...
Dispersion Characteristics and Circulation Associated with Boreal Summer Westward-Traveling Mixed Rossby–Gravity Wave–Like Disturbances
Publisher: American Meteorological Society
Abstract: AbstractAn algorithm has been developed to track synoptic-scale, westward-traveling mixed Rossby?gravity (MRG) wave?like disturbances with a cross-equatorial component. Applied to space?time-filtered meridional wind data, ...

CMIP5 Projections of Two Types of El Niño and Their Related Tropical Precipitation in the Twenty-First Century
Publisher: American Meteorological Society
Abstract: AbstractFuture projections of the eastern-Pacific (EP) and central-Pacific (CP) types of El Niño in the twenty-first century, as well as their associated tropical circulation and precipitation variability, are investigated ...
Potential Predictability of the Silk Road Pattern and the Role of SST as Inferred from Seasonal Hindcast Experiments of a Coupled Climate Model
Publisher: American Meteorological Society
Abstract: The Silk Road pattern (SR) is a leading mode of atmospheric circulation over midlatitude Eurasia in boreal summer. Its temporal phase is known to be unpredictable in many models. Previous studies have not reached a clear ...
Attenuation of Central Pacific El Niño Amplitude by North Pacific Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: There exists a pronounced asymmetry between the amplitudes of central Pacific (CP) and eastern Pacific (EP) El Niño sea surface temperature anomalies (SSTA). The present study examines such an asymmetry and its relationship ...
