The rare case of Hurricane Catarina (2004) over the South Atlantic Ocean: The origin of its precipitation through a Lagrangian approach
Tropical cyclones (TCs) are extremely rare over the South Atlantic Ocean (SATL) due to predominantly unfavourable conditions, that is, cool sea-surface temperature and strong vertical wind shear. Nevertheless, unusual conditions over SATL associated with a blocking system promoted the formation of H...

Tropical cyclones (TCs) are extremely rare over the South Atlantic Ocean (SATL) due to predominantly unfavourable conditions, that is, cool sea-surface temperature and strong vertical wind shear. Nevertheless, unusual conditions over SATL associated with a blocking system promoted the formation of Hurricane Catarina from an extratropical precursor in late March 2004, which produced heavy rainfall over the states of Santa Catarina and the Rio Grande do Sul in south Brazil. This work identifies the moisture sources for the precipitation produced by Catarina along its 6-hourly trajectory, through a Lagrangian moisture-tracking method. We extracted the pathways of precipitating air parcels within the cyclone’s outer radius from the global outputs of the FLEXPART model forced with the ERA-Interim reanalysis. Our findings revealed the terrestrial source in south-southeastern Brazil (SEB) and the oceanic source limited by the box between 20-40◦S and 30–50◦W over SATL (WSATL) as the principal moisture sources, with the overall support of ∼27% and ∼66%, respectively.
