RISObservations of Large-Scale Ocean–Atmosphere Interaction in the Southern Hemisphere
Publisher: American Meteorological Society
Abstract: The authors provide a detailed examination of observed ocean?atmosphere interaction in the Southern Hemisphere (SH). Focus is placed on the observed relationships between variability in SH extratropical sea surface temperature ...
Observational Evidence of Reemergence in the Extratropical Southern Hemisphere
Publisher: American Meteorological Society
Abstract: Observations of subsurface temperatures are used to examine the winter-to-winter ?reemergence? of sea surface temperature (SST) anomalies in the extratropical South Pacific Ocean. Reemergence is the mechanism through which ...
North Atlantic Atmosphere–Ocean Interaction on Intraseasonal Time Scales
Publisher: American Meteorological Society
Abstract: The authors examine wintertime atmosphere?ocean interaction on weekly time scales over the North Atlantic sector. Consistent with previous results, it is found that the strongest interactions between the ocean and atmosphere ...
Influence of Tropical Pacific Sea Surface Temperature on the Genesis of Gulf Stream Cyclones
Publisher: American Meteorological Society
Abstract: his study investigates the relationship between tropical Pacific sea surface temperature (SST) variability and cyclogenesis over the Gulf Stream region of the North Atlantic. A cyclone identification scheme and Lagrangian ...
Teleconnections between Tropical Pacific SST Anomalies and Extratropical Southern Hemisphere Climate
Publisher: American Meteorological Society
Abstract: eleconnections from tropical Pacific sea surface temperature (SST) anomalies to the high-latitude Southern Hemisphere (SH) are examined using observations and reanalysis. Analysis of tropical Pacific SST anomalies is ...
Extratropical Cyclogenesis Changes in Connection with Tropospheric ENSO Teleconnections to the North Atlantic: Role of Stationary and Transient Waves
Publisher: American Meteorological Society
Abstract: AbstractThis study investigates mechanisms for changes in wintertime extratropical cyclogenesis over North America and the North Atlantic during different phases of El Niño?Southern Oscillation (ENSO). Insights into the ...
Seasonal Relationships between Large-Scale Climate Variability and Antarctic Sea Ice Concentration
Publisher: American Meteorological Society
Abstract: he observed relationships between anomalous Antarctic sea ice concentration (SIC) and the leading patterns of Southern Hemisphere (SH) large-scale climate variability are examined as a function of season over 1980?2008. ...
Tropical Connections to Climatic Change in the Extratropical Southern Hemisphere: The Role of Atlantic SST Trends
Publisher: American Meteorological Society
Abstract: he austral spring relationships between sea surface temperature (SST) trends and the Southern Hemisphere (SH) extratropical atmospheric circulation are investigated using an atmospheric general circulation model (AGCM). A ...
On the Persistence of Cold-Season SST Anomalies Associated with the Annular Modes
Publisher: American Meteorological Society
Abstract: n this study, a simple stochastic climate model is used to examine the impact of the ocean mixed layer depth, surface turbulent energy fluxes, and Ekman currents on the persistence of cold-season extratropical sea surface ...
Skillful All-Season S2S Prediction of U.S. Precipitation Using the MJO and QBO
