“…The functional form of the autocorrelation depends on the physical properties, the considered scales (e.g., synoptic versus mesoscale) and the area. Many studies have estimated autocorrelation functions through analysis of in-situ ocean measurements [e.g., Meyers et al, 1991;Chu et al, 2002;Delcroix et al, 2005] and satellite observations [e.g., Kuragano and Kamachi, 2000;Hosoda and Kawamura, 2004;Tzorti et al, 2016]. Generally the estimated autocorrelation functions have exponential or Gaussian form [Molinari and Festa, 2000].…”
