On the y axis there is
distance along the trajectory represented as time normalized by the
inertial oscillation period (40 h). The cross-track distance measures
distance from the trajectory of typhoon Jangmi. The position of typhoon
Hagupit is at −140 km. It can be seen that there is positive
anomaly to the left and negative anomaly to the right of Jangmi’s
track. Color scale represents temperature anomaly [C]
