abstract = "An analysis of two groups of near-surface intense cyclonic
vortices, one off the southeastern Brazil coast and the other off
the Mozambique coast, in the period 19792012 is undertaken for
comparison of their characteristics with the help of the TRACK
algorithm and the NCEP2 Reanalysis data sets. The aim is to
understand the nature of intense cyclogeneses in those two
subtropical coastal regions. Although the two groups form in
almost the same latitude belt and under similar conditions and
thus have some common features, they differ in several evolution
and movement characteristics. The South American intense cyclones
are more frequent. They move rapidly into southern South Atlantic
while the African cyclones remain quasi-stationary during the
first 2 days of their life time. Thermal structures show that the
Mozambique Channel region presents more conditional instability.
The South American intense cyclones present more kinetic energy
than their counterparts in the first 2 days. The precipitation
around the South American cyclones decreases gradually. The
Mozambique Channel cyclones gain kinetic energy after moving away
from the Madagascar Island and preserve their baroclinity longer
and therefore the mean precipitation rate around their centres
remains constant. The sea surface temperature, the geographical
features and the circulation characteristics of the two regions
are responsible for the differences. Eventually, after 4 days of
their formation, cyclones of both the groups join the Southern
Hemispheric extratropical storm-tracks.",
