Dear Tim,

I guess you know that HadCM3 does very bad job over the
tropical Atlantic sector. The appauling representation of
the interannual varaibility and its seasonal dependency
could be due to a suppressed seasonal phase-locking structure of the
Pacific ENSO in the model (compared with observational
evidence). We cannot possibly use HadCM3 for seasonal
forecasting over the Atlantic-Europe sector, until this
problem is sorted out. I provoked COAPEC committee members when I
gave a short talk on this issue. Because I didn't get COAPEC core team
job (for seasonal forecast), I no longer intend to directly contribute to
the modification of HadCM3, but will write up a paper on my analysis of
HadCM3 ctrl runs, before I move to Sheffield.

As Adam's pproject would heavily rely on the control runs, I have been
worried about it. We hope that decadal variability produced by the
model is not as poor as the interannual counterpart. I have to work on
decadal modulation of the interannual variabitity, though....

Cheers,

-Itsuki-
