Wind Data
Thanks SaturnV, have checked out the link. From what I can gather, did the drift models just look at surface current effects ? What I had in mind was just focusing on the galley section and using wind effects only (eg assume object attained x% of average wind speed each day with x between 25% and 70%).
I imagine that's what the submerged parameter in the BEA analysis is about, but for currents.
My French isn't reliable but did their model combine both wind and current, eg an object 50% submerged got 50% of the current effect and 50% of that due to wind, or was it just factoring in the area subject to the current forces and drag, with sub-models/assumptions used to determine the actual physical effects of both. ?
What I was hankering after was whether the wind-only backtrack on the galley section gave any course near the pollution spot. A simple parameterised model should be do-able if the daily wind vectors are known.
