RISOrigin of the Summertime Synoptic-Scale Wave Train in the Western North Pacific
Publisher: American Meteorological Society
Abstract: The origin of the summertime synoptic wave train in the western North Pacific is investigated with a multilevel, nonlinear baroclinic model. A realistic three-dimensional summer mean state is specified and eigenvectors are ...
The Record-Breaking Hot Summer in 2015 over Hawaii and Its Physical Causes
Publisher: American Meteorological Society
Abstract: AbstractHawaiian surface air temperature (HST) during the summer of 2015 (from July to October) was about 1.5°C higher than the climatological mean, which was the hottest since records began in 1948. In the context of ...
Energy Spectrum Characteristics of Boreal Summer Intraseasonal Oscillations: Climatology and Variations during the ENSO Developing and Decaying Phases
Publisher: American Meteorological Society
Abstract: The geographic-dependence characteristics of the energy spectrum of the boreal summer intraseasonal oscillation (BSISO; May?October) over the Indo?western Pacific region were analyzed using 25-yr (1979?2003) observational ...
Upscale Feedback of Tropical Synoptic Variability to Intraseasonal Oscillations through the Nonlinear Rectification of the Surface Latent Heat Flux
Publisher: American Meteorological Society
Abstract: Analysis of observational data suggests two-way interactions between the tropical intraseasonal oscillation (ISO) and synoptic-scale variability (SSV). On one hand, SSV is strongly modulated by the ISO; that is, a strengthened ...
Tropical Cyclogenesis Associated with Rossby Wave Energy Dispersion of a Preexisting Typhoon. Part I: Satellite Data Analyses
Publisher: American Meteorological Society
Abstract: The structure and evolution characteristics of Rossby wave trains induced by tropical cyclone (TC) energy dispersion are revealed based on the Quick Scatterometer (QuikSCAT) and Tropical Rainfall Measuring Mission (TRMM) ...
Planetary Scale Selection of the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: Numerical experiments with a 2.5-layer and a 2-level model are conducted to examine the mechanism for the planetary scale selection of the Madden?Julian oscillation (MJO). The strategy here is to examine the evolution of ...
Relative Roles of Circumnavigating Waves and Extratropics on the MJO and Its Relationship with the Mean State
Publisher: American Meteorological Society
Abstract: set of atmospheric general circulation model (GCM) experiments is designed to explore the relative roles of the circumnavigating waves and the extratropics on the Madden?Julian oscillation (MJO). In a ?control? simulation, ...
Entropy Evolution Characteristics Associated with the Development of the South Asian Monsoon
Publisher: American Meteorological Society
Abstract: he structure and evolution characteristics of atmospheric entropy production associated with the climatologic monsoon onset and evolution were investigated using the National Centers for Environmental Prediction (NCEP) ...
Factors Controlling Multiple Tropical Cyclone Events in the Western North Pacific
Publisher: American Meteorological Society
Abstract: The statistical feature of occurrence of multiple tropical cyclone (MTC) events in the western North Pacific (WNP) is examined during summer (June?September) for the period of 1979?2006. The number of MTC events ranged ...
A Simple Analytical Model for Understanding the Formation of Sea Surface Temperature Patterns under Global Warming
Publisher: American Meteorological Society
Abstract: ow sea surface temperature (SST) changes under global warming is critical for future climate projection because SST change affects atmospheric circulation and rainfall. Robust features derived from 17 models of phase 5 of ...
