Dynamics of the Northern Annular Mode at Weekly Time Scales
Publisher: American Meteorological Society
Abstract: apid onsets of positive and negative tropospheric northern annular mode (NAM) events during boreal winters are studied using ERA-Interim datasets. The NAM anomalies first appear in the North Pacific from low-frequency ...
The North Atlantic Oscillation Response to Large-Scale Atmospheric Anomalies in the Northeastern Pacific
Publisher: American Meteorological Society
Abstract: ngredients in the North Pacific flow influencing Rossby wave breakings in the North Atlantic and the intraseasonal variations of the North Atlantic Oscillation (NAO) are investigated using both reanalysis data and a ...
The Link between the North Pacific Climate Variability and the North Atlantic Oscillation via Downstream Propagation of Synoptic Waves
Publisher: American Meteorological Society
Abstract: he North Atlantic Oscillation (NAO) response to the northeast Pacific climate variability is examined using the ERA-40 dataset. The main objective is to validate a mechanism involving downstream wave propagation processes ...
