Dear Xuguang,
on the EUG XI conference (European Union of Geosciences), Strassbourg
this year there was in one of the symposia also a contribution on
model/data comparisons (various models).
One point that might be interesting for you was: When the development
of various modelled parameters is plotted against time the first 12
(20) modelled months are factually not usable.
You might see one of these effects.
If after two years the effects mentioned by you still persist, more
checking is needed.
Best regards, Peter
