SHR space-time diagram
This sea height residual (SHR) space-time diagram provides useful means to identify the motion of the NBC retroflection and the shedding and translation of rings. These anticyclonic warm rings can usually be identified by their large positive SHR values, red colors in the graphics.
The SHR fields are obtained by removing the anual signal to the sea height anomaly (SHA) fields from satellite altimetry (AVISO). Then, mean SHR values are computed for same longitude sections along a corridor to obtain the space-time dependent SHR dataset. This space-time diagram is updated monthly.
