Figure 9

Wave activity flux (×106) for May-Jun 2016. The arrows represent the wave flux Wx and Wy, and the shading represents the wave flux divergence, wave flux divergence indicates Rossby wave sources and convergence indicates Rossby wave sinks. Following Takaya and Nakamura [59], the wave flux is parallel to the phase velocity of the Rossby wave packages.
