The new Mozambique heat flow map shows a predominantly low offshore heat flow of around 50 mW/m 2 , associated with the Jurassic and early Cretaceous age of the oceanic crust. Tropical cyclones (TC) in the Southwest Indian Ocean represent approximately 15% (12 TCs per year in average) of all TCs that form globally every year. Some of these cyclones may become a crucial component of weather over the Mozambique Channel (MC) since some TCs travelling over its waters. ion and vertical supply of nutrients. Agulhas leakage is thought to modulate Atlantic meridional overturning.
