    "abstract": "The properties of mesoscale Lagrangian turbulence in the Adriatic Sea are\nstudied from a drifter data set spanning 1990-1999, focusing on the role of\ninhomogeneity and nonstationarity. A preliminary study is performed on the\ndependence of the turbulent velocity statistics on bin averaging, and a\npreferential bin scale of 0.25 is chosen. Comparison with independent estimates\nobtained using an optimized spline technique confirms this choice. Three main\nregions are identified where the velocity statistics are approximately\nhomogeneous: the two boundary currents, West (East) Adriatic Current, WAC\n(EAC), and the southern central gyre, CG. The CG region is found to be\ncharacterized by symmetric probability density function of velocity,\napproximately exponential autocorrelations and well defined integral quantities\nsuch as di usivity and time scale. The boundary regions, instead, are\nsignificantly asymmetric with skewness indicating preferential events in the\ndirection of the mean flow. The autocorrelation in the along mean flow\ndirection is characterized by two time scales, with a secondary exponential\nwith slow decay time of 11-12 days particularly evident in the EAC region.\nSeasonal partitioning of the data shows that this secondary scale is especially\nprominent in the summer-fall season. Possible physical explanations for the\nsecondary scale are discussed in terms of low frequency fluctuations of\nforcings and in terms of mean flow curvature inducing fluctuations in the\nparticle trajectories. Consequences of the results for transport modelling in\nthe Adriatic Sea are discussed.",
