in the
opposite region from the right side maximum cooling predicted
by the model. As with Hagupit, it can be seen that
the mixed layer temperature predicted by the model agrees
well with the observed conditions. Although part of the day-
1 in situ profile is missing above 40 m, one expects that it
is well mixed and similar to the prior profile under strong
wind conditions evident in Fig. 5. The model also does well
in predicting the depth of the mixed layer particularly during
days 1 and 2. Note that the observed cooling comes to an
end on 27 September after the SSTs reach a minimum temperature
of 28.6 C. The model performs well in this regard
with no change in temperature detected between days 2 and
3. The model on day 3 shows a relatively deeper MLD compared
with the observations but that might be due to thermocline
depth modified by the internal waves or other physical
processes that were not represented in the model. Note that
modeled profile has not changed from the previous day, when
thermocline structure of observed profiles is clearly different.
Since the typhoon at this time already passed by the float location,
it is likely that the observed change is due to factors
other than interaction with typhoon Jangmi. Model estimates
of the MLD and temperature gradient within the thermocline
are quite good with the exception of day 3.
