Figure 2
(a) Time series of daily EKE (units: cm2/s2) at the fixed point during 1 May 1993 to 30 June 1994. The light blue/red shadings show the impact stages when the fixed point is in the impacting area of CEs/AEs. The thick blue/red lines indicate the Lagrangian EKE (LEKE, units: cm2/s2) of the corresponding CEs/AEs during the impact stages. The vertical dashed lines denote the day when the fixed point is overlaid by the eddy center. (b) Trajectories of the CEs and AEs with blue and red lines, respectively. The locations where the eddies originally generated are marked with star symbols while the fixed point is marked with a black dot symbol. (c) Schematic diagram of LEKE calculation. The white dots represent the eddy center and the shading circles represent the impacting area S. The figure was made using NCAR Command Language 6.4.0 (https://www.ncl.ucar.edu/).
