Editing Agulhas Current (section)

===Agulhas meanders and Natal pulses===
As the Agulhas Current flows south along the African east coast, it tends to bulge inshore frequently, a deviation from the current's normal path known as Agulhas Current meanders (ACM).  These bulges are occasionally (1-7 times per year) followed by a much larger offshore bulge, known as Natal pulses (NP).  Natal pulses move along the coast at {{Convert|20|km|abbr=on}} per day.  An ACM can bulge up to {{Convert|20|km|abbr=on}} and a NP up to {{Convert|120|km|abbr=on}} from the current's mean position.<ref>{{Harvnb|Jackson|Rainville|Roberts|McQuald|2012}}</ref>
The AC passes {{Convert|34|km|abbr=on}} offshore and an ACM can reach {{Convert|123|km|abbr=on}} offshore.  When the AC meanders, its width broadens from {{Convert|88|km|abbr=on}} to {{Convert|125|km|abbr=on}} and its velocity weakens from {{Convert|208|cm/s|abbr=on}} to {{Convert|136|cm/s|abbr=on}}.  An ACM induces a strong inshore counter-current.<ref>{{Harvnb|Leber|Beal|2012}}</ref>

Large-scale cyclonic meanders known as Natal pulses are formed as the Agulhas Current reaches the continental shelf on the South African east-coast (i.e. the eastern Agulhas Bank off [[Natal Province|Natal]]).  As these pulses moves along the coast on the Agulhas Bank, they tend to pinch off Agulhas rings from the Agulhas Current.  Such a [[ring shedding]] can be triggered by a Natal pulse alone, but sometimes meanders on the [[Agulhas Return Current]] merge to contribute to the shedding of an Agulhas ring.<ref>{{Harvnb|Leeuwen|Ruijter|Lutjeharms|2000|loc=Abstract}}</ref>
