On the left side of
Jangmi’s track the anomaly is stronger, which means that
two collocated typhoons caused cooling of 0.25 C stronger
then Jangmi alone. This can be explained by the absence
of Hagupit’s forcing on the ocean; note that −100 km is
in the peak region of the Hagupit-induced cold wake. On
the right side of typhoon Jangmi’s track, the joint effect of
Hagupit and Jangmi is only 0.06 C stronger then cooling
from Jangmi alone – which is small.
