Start dumps: $DUMPS/xahiya.da00c10 $DUMPS/xahiyo.da00c10

Diags
Userprestash files
History: yabkb -> a -> yabes -> f -> e -> c -> a -> yabad -> a -> yaauo -> n -> yaasc -> yaaoa

This run was intended as a test of EVP seaice. But a side effect is to allow me to look at the "QT_POS problem" [Update: 2002/12/16: this problem appears to be a consequence of running with GHG incs; see yabwb a new control which cures this problem]. The run is at 32-bit, with non-standard (but not too unstandard) seaice.

To look at this further with diags, see yabeu.

We process the output by:

egrep 'QT_POS|new file yabkba.da' pe1 > pe1-proc
qtpos.pl pe1-proc > pe1-proc1

and for pe0. This gives a visual representation of how often, per dump period, QT_POS whinges about losing moisture, and on what levels. The results are in:

pe0-proc1

pe1-proc1

The results are somewhat curious. pe's 0 and 1 are not clearly connected. Pe0 shows no problem till 2006, then has 4 years of trubble, then clears out (and has a seasonal cycle with vague autumn peaks during those 4 years). Pe1 trubble starts in 2003, has an extended clear spell, and restarts at the end. Well what does that mean I wonder?
