The full vertical structure of the temperature anomalies
can be seen in the longitude–depth sections along
the equator (Fig. 15); note the expanded depth axis
in the upper 200 dbar. Significant temperature anomalies
fill the entire Pacific basin down to 1000 dbar.
The largest anomalies ( 1 ◦C) are in the thermocline,
where the vertical temperature stratification is largest.
Although the anomalies decrease in magnitude with
depth ( 0.1 ◦C at 600 dbar, 0.05 ◦C at 900 dbar),
they are still large as they are comparable to the amplitude
of the seasonal cycle ( 0.08 ◦C at 600 dbar,
0.07 ◦C at 900 dbar). Individual MJO events can
have much larger temperature anomalies; for examplys.
