Extreme heatwave over Eastern China in summer 2022: the role of three oceans and local soil moisture feedback (2023, methodology): “The wave activity flux, which indicates the direction of the Rossby wave energy propagation, was calculated following Takaya and Nakamura (2001).”
Climate Fluctuations of Tropical Coupled Systems—The Role of Ocean Dynamics (2006, methodology): “The scenario is confirmed by calculating the wave activity flux (cf. Plumb 1986; Takaya and Nakamura 2001) by Guan and Yamagata (2003).”
An Observed Connection between the North Atlantic Oscillation and the Madden-Julian Oscillation (2009, methodology): “To analyze the time evolution of the wave activity ﬂux associated with the extratropical circulation anomalies, the wave activity ﬂux vector ( W vector) proposed by Takaya and Nakamura (2001) is calculated, which is based on the conservation of wave activity pseudomo-mentum.”
The Link between Rossby Wave Breakings and Weather Regime Transitions (2011, methodology): “To confirm the Rossby wave propagation, the horizontal wave-activity flux WH derived by Takaya and Nakamura (2001) for a zonally varying basic flow on the pressure coordinates (Equation C5 of their paper) is computed for ψL at lag T-6 days and plotted in Fig.”
Observed Associations Among Storm Tracks, Jet Streams and Midlatitude Oceanic Fronts (2013, result): “Consistent with this eddy forcing, a wave-activity flux of stationary Rossby waves [Takaya and Nakamura, 2001] is strongly divergent from the anomalies that resemble the Pacific/North American (PNA) pattern [Wallace and Gutzler, 1981], which is regarded as a preferred mode of variability in the…”
Influence of the Gulf Stream on the Barents Sea ice retreat and Eurasian coldness during early winter (2014, background): “…to originate from the east coast of North America, in particular the Gulf Stream and North Atlantic regions, in association with the propagation of wave-activity flux (Takaya and Nakamura 2001) which represents propagation of quasi-stationary Rossby waves (indicated by arrows in figure 2(b)).”
The Growth and Triggering Mechanisms of the PNA : A MJO-PNA Coherence (2008, background): “The arrows superimposed indicate horizontal components of the wave-activity flux (WAF) defined by Takaya and Nakamura (2001), which is independent of wave phase and parallel to the local group velocity of Rossby waves in a zonally asymmetric climatological flow.”
Dynamical implications of the orientation of atmospheric eddies: a local energetics perspective (2007, background): “The 2-D E–P flux vector has been extended to a 3-D flux vector that satisfies a conservation relation of a pseudo energy/momentum quantity for a zonally varying basic flow (Andrews, 1983; Plumb, 1986; Takaya and Nakamura, 2001).”
