Comparison of the Atmospheric 200 hPa Jet’s Analyses between Proper Orthogonal Decomposition and Advanced Dynamic Mode Decomposition Method

Figure 7

The five DMD modes identified by the SPDMD from the 200 hPa jet flow (a–e correspond to the 1–5th modes, velocity is visualized by vector plots, and the background color contours visualize the vertical vorticity component).
