Abstract

The annual obduction rate enhancement induced by tropical cyclones is estimated on the basis of SODA outputs and tropical cyclone-induced mixed layer deepening obtained from a hurricane–ocean coupled model. Averaged over the period from 1984 to 2005, the obduction rate enhancement is estimated to be 2.1 Sv in the North Atlantic and 4.2 Sv in the North Pacific; such enhancement is mainly confined to the latitudinal band from 10°N to 30°N. The obduction rate enhancement induced by tropical cyclones in the North Atlantic and North Pacific both show strong interannual variability, which is mainly dominated by powerful hurricanes/typhoons.
