    "abstract": "The EOLE Experiment is revisited to study turbulent processes in the lower\nstratosphere circulation from a Lagrangian viewpoint and resolve a discrepancy\non the slope of the atmospheric energy spectrum between the work of Morel and\nLarcheveque (1974) and recent studies using aircraft data. Relative dispersion\nof balloon pairs is studied by calculating the Finite Scale Lyapunov Exponent,\nan exit time-based technique which is particularly efficient in cases where\nprocesses with different spatial scales are interfering. Our main result is to\nreconciliate the EOLE dataset with recent studies supporting a k^{-5/3} energy\nspectrum in the range 100-1000 km. Our results also show exponential separation\nat smaller scale, with characteristic time of order 1 day, and agree with the\nstandard diffusion of about 10^7 m^2/s at large scales. A still open question\nis the origin of a k^{-5/3} spectrum in the mesoscale range, between 100 and\n1000 km.",
