RISA Pan–North Pacific Wintertime Surface Air Temperature Pattern Influenced by the SST Anomalies over the Kuroshio and Oyashio Extension
Publisher: American Meteorological Society
The Eddy–Mean Flow Interaction and the Intrusion of Western Boundary Current into the South China Sea–Type Basin in an Idealized Model
Publisher: American Meteorological Society
Abstract: n this paper, an ideal model of the role of mesoscale eddies in the Kuroshio intruding into the South China Sea (SCS) is developed, which represents the northwestern Pacific and the SCS as two rectangular basins connected ...
Dynamical Relationship between the Phase of North Atlantic Oscillations and the Meridional Excursion of a Preexisting Jet: An Analytical Study
Publisher: American Meteorological Society
Abstract: In this paper, it is shown from an analytical solution that in the presence of a preexisting jet the interaction between the zonal jet and the topography of the land?sea contrast (LSC) in the Northern Hemisphere (NH) tends ...
Local and External Moisture Sources for the Arctic Warming over the Barents–Kara Seas
Publisher: American Meteorological Society
Abstract: AbstractWater vapor is critical to Arctic sea ice loss and surface air warming, particularly in winter. Whether the local process or poleward transport from lower latitudes can explain the Arctic warming is still a ...
Increased Quasi Stationarity and Persistence of Winter Ural Blocking and Eurasian Extreme Cold Events in Response to Arctic Warming. Part II: A Theoretical Explanation
Publisher: American Meteorological Society
Abstract: AbstractIn Part I of this study, it was shown that the Eurasian cold anomalies related to Arctic warming depend strongly on the quasi stationarity and persistence of the Ural blocking (UB). The analysis here revealed that ...

Spatial Pattern and Zonal Shift of the North Atlantic Oscillation. Part I: A Dynamical Interpretation
Publisher: American Meteorological Society
Abstract: This paper presents a possible dynamical explanation for why the North Atlantic Oscillation (NAO) pattern exhibits an eastward shift from the period 1958?77 (P1) to the period 1978?97 (P2) or 1998?2007 (P3). First, the ...
Inverse Energy Cascades in an Eddy-Induced NAO-Type Flow: Scale Interaction Mechanism
Publisher: American Meteorological Society
Abstract: n this paper, based on a new wave?eddy interaction framework, the interaction mechanism between the North Atlantic Oscillation (NAO) and synoptic-scale eddies is revealed by using the analytical solutions of a two-scale ...
A Nonlinear Theory of Atmospheric Blocking: A Potential Vorticity Gradient View
Publisher: American Meteorological Society
Abstract: AbstractIn this paper, an extended nonlinear multiscale interaction model of blocking events in the equivalent barotropic atmosphere is used to investigate the effect of a slowly varying zonal wind in the meridional direction ...
Spatial Pattern and Zonal Shift of the North Atlantic Oscillation. Part II: Numerical Experiments
Publisher: American Meteorological Society
Abstract: In this part, the spatial evolution of an initial dipole anomaly in a prescribed jet is at first investigated by numerically solving linear and nonlinear models without forcing in order to examine how the spatial pattern ...
