v14 v15 36 36 ARIANE also received support from INSU in the framework of an «Action Thématique Innovante» project, for the period 09/1998-08/2000. 37 37 38 39 The earliest developments date back to Summer 1992, with the first coding of the analytical scheme that computes 3D streamlines in a C-gridded velocity field [see Speich, 1992 for some pioneer visualizations]. This scheme is still in use in ARIANE, and defines the core of all our other downstream diagnostics related to the tracing of water masses in an OGCM.[[BR]] 40 41 Such off-line diagnostics were initiated by Döös [1995] and we drew our inspiration from his approach to develop our own methodology. Most of the technical details associated with our computations are described in the appendices of three recent papers [Blanke and Raynaud, 1997; Blanke et al., 1999; 2001], together with some useful figures.[[BR]] 38 42 39 43 40 The earliest developments date back to Summer 1992, with the first coding of the analytical scheme that computes 3D streamlines in a C-gridded velocity field [see Speich, 1992 for some pioneer visualizations].

We wish to thank here the whole OPA modeling group, led by Pascale Delecluse and Gurvan Madec at LODYC, for its constant effort to develop, improve and validate this OGCM. 44 45 45 None of the present work could have been done without the availability of a high-performance OGCM.

Here follow some of the possible options associated with the use of ARIANE: 46 Though still crude, ARIANE is able to perform a large number of interesting computations. Here follow some of the possible options associated with the use of ARIANE: 48 47 - QUALITATIVE diagnostics: a few particles (typically less than 10), with a steady recording of the positions along their trajectories. 49 48 - QUANTITATIVE diagnostics: many (thousands of !) particles, with statistics available for the initial and final positions, and with the diagnostic of the main pathways.
