RISThe Coupled Patterns between Sea Level Pressure and Sea Surface Temperature in the Midlatitude North Atlantic
Publisher: American Meteorological Society
Abstract: Monthly variability of atmosphere-ocean interactions in the midlatitude North Atlantic during the winter months (November?April) is examined. Composite and singular value decomposition (SVD) analyses are applied to the ...
Dynamics of the Early and Middle Winter Atmospheric Responses to the Northwest Atlantic SST Anomalies
Publisher: American Meteorological Society
Abstract: The differences between early and middle winter atmospheric responses to the sea surface temperature anomalies (SSTA) in the northwest Atlantic are examined using a linear baroclinic model. Using a global spectral model, ...
A Teleconnection Study of Interannual Sea Surface Temperature Fluctuations in the Northern North Atlantic and Precipitation and Runoff over Western Siberia
Publisher: American Meteorological Society
Abstract: The spatial distributions of northern North Atlantic sea surface temperature and the high-latitude Northern Hemisphere sea level pressure anomalies averaged over six consecutive warm SST winters (1951?1956) and six consecutive ...
Mechanisms Determining the Atmospheric Response to Midlatitude SST Anomalies
Publisher: American Meteorological Society
Abstract: Previous GCM experiments demonstrated that a model atmosphere produces two different responses to a midlatitude warm SST anomaly over the Pacific under perpetual January and February conditions. To elucidate the mechanisms ...
Relationships between Atmospheric Internal Variability and the Responses to an Extratropical SST Anomaly
Publisher: American Meteorological Society
Abstract: The January and February responses of a GCM to an imposed extratropical Pacific SST anomaly are compared with the patterns of the model's internal variability. Relevant patterns of internal variability are diagnosed from ...
Mechanisms for the NAO Responses to the North Atlantic SST Tripole
Publisher: American Meteorological Society
Abstract: The response of an atmospheric general circulation model (GCM) to the North Atlantic SST tripole exhibits both symmetric and asymmetric components with respect to the sign of the SST anomaly. The symmetric part of the ...

The Transient Atmospheric Circulation Response to North Atlantic SST and Sea Ice Anomalies
Publisher: American Meteorological Society
Abstract: The objective of this study is to investigate the transient evolution of the wintertime atmospheric circulation response to imposed patterns of SST and sea ice extent anomalies in the North Atlantic sector using a large ...
Hindcasts of Tropical Atlantic SST Gradient and South American Precipitation: The Influences of the ENSO Forcing and the Atlantic Preconditioning
Publisher: American Meteorological Society
Abstract: Hindcast experiments for the tropical Atlantic sea surface temperature (SST) gradient G1, defined as tropical North Atlantic SST anomaly minus tropical South Atlantic SST anomaly, are performed using an atmospheric general ...
The Modeled Atmospheric Response to Midlatitude SST Anomalies and Its Dependence on Background Circulation States
Publisher: American Meteorological Society
Abstract: The atmospheric response to a midlatitude SST anomaly in the North Pacific and its dependence on background flow are examined in a GCM. Experiments are conducted using the same warm SST anomalies but two different model ...
