Conteúdo:

Intense wind events at the southern Brazilian coast cause severe socio-economic losses. Generally, such
events have been associated with extratropical cyclones over the Southwest Atlantic Ocean. The purpose of this study is
to identify favoured locations and the processes through which the winds are associated with the extratropical cyclones.
Using a statistical analysis, the wind speed observed at nine meteorological stations was compared with cyclone depth
and offshore distance. Both cyclone depth and location were obtained through an objective procedure of identifying and
tracking. Generally, the winds are well associated with the extratropical cyclones only south of 28 °S. Altitude also plays
an important role in this relationship. Furthermore, the cyclones influence the observed wind field up to 1200 km inland
at higher latitude locations. For stations near 28 °S, cyclones further from the coast have an influence, but with smaller
statistical significance.
