ACC effective diffusivity results

Section A: Links to summary pages

Section B: List of calculations, links to datasets, and comments

Quarter degree

L-kdep (quarter degree K10, K100)

L and ftlehat (quarter degree K100)

Summary

1. K10 seems to be too small diffusion at this resolution
2. Relaxation doesn't make too much difference
3. Keff and Lyap (ie ftlehat) don't have v similar structure but similar maginitude when appropriately scaled (note - peaks at edges of ftlehat are spurious artefacts of averaging method).

1. Keff calculations are normalised by Leq from K10000 run
2. FTLE calcs are after t=200days (ie a couple of eddy turnover times)
3. Latitudes are: lats=-29.775-0.05*findgen(145)

Twentieth degree

L-kdep (twentieth degree K10, K50)

L (twentieth and quarter degree K10)

L (twentieth K50 and quarter K100)

L and ftlehat (twentieth K50)

L*knum (twentieth K50 and K10), knum estimated to be 16.6719 (k=10) and 60.1074 (k=50)

Summary

1. K10 is indeed too small at quarter degree
2. K10 and K50 quite similar to eachother and also to K100 at quarter degree - all have lowest values of about 500m2/s and highest values of about 2000m2/s
3. Keff and Lyap (ie ftlehat) don't have same structure but similar maginitude when appropriately scaled (note - peaks at edges of ftlehat are spurious artefacts of averaging method).

Twentieth degree (BIGBIT)

patch results

L and ftlehat (twentieth K50)

Summary

1. Some similarity between patch results
2. Plausible similarity between Keff at K50 (not K10) and lyap exps

Twentieth degree (BIGBITII)

patch results

L and ftlehat (twentieth K50)

Summary

1. Some similarity between patch results (esp for zoom of tracer and patch; differences in zoom of Keff and patch - warning re interpretation of local features on gloabl Keff picture)
2. Plausible similarity between Keff at K50 and K10 and lyap exps (also ftlehat)

Twentieth degree (BIT01again and BIT01againNOMEAN )

patch results

L and ftlehat (twentieth K10)

Summary

1. Some similarity between patch results - definitely correct latitude ranges.

Hundredth degree
