5.2.1 Temperature
There are large-scale, coherent, statistically significant,
MJO temperature anomalies in the deep ocean throughout
the tropical Pacific. For example, in phase 8 there
are warm (cold) anomalies at 950 dbar in the central
(eastern) Pacific (Fig. 14). The available Argo observations
only extend down to around 1000 dbar in the
eastern Pacific, so 950 dbar was chosen as the deepest
level at which there is satisfactory coverage. There are
similarly sized 950-dbar temperature anomalies in all
other phases of the MJO. These are summarised in a
Hovm¨oller diagram of equatorial 950-dbar temperature
anomalies (Fig. 10b). Eastward propagation can clearly
be seen.
