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

Figure 3

The first eight POD modes extracted from the 200 hPa jet (a–h correspond to the 1–8th modes; wind velocity visualized by vector plots and the background color contours visualize the vertical vorticity component).
