Modern research has challenged that assumption, and indicates that rather than a strong western boundary current, there are often a series of large anti-cyclonic eddies in the channel.
Direct evidence for these eddies has been found in satellite altimetry data,[1] ship borne surveys,[2] and moored current meter records.
Nonetheless, it is impossible to rule out the possibility that the Mozambique Current may appear intermittently, for short durations.
Indeed, numerical model simulations in the Mozambique Channel show the appearance of a current on the Mozambican Coast, during periods between eddies.
[2] The exact causal mechanism, and location of the eddies formation is still debated.
