“…The authors found that CFSR has the highest number of cyclones, while ERAI the lowest. de Jesus et al (2020), through an ensemble of ERAI and CFSR reanalyses, found a negative trend in the frequency of cyclones in the period 1979 to 2005, which is in agreement with Reboita et al (2015) for the time slice 1980 to 2000.…”

“…The southeast coast of Argentina (45 • S-50 • S) is also considered a cyclogenetic zone [141][142][143][144][145][146][147], with an average incidence of 62 cyclogeneses per year (the result was computed by a cyclone tracking algorithm through cyclonic relative vorticity) [146]. This feature results from the regeneration of systems moving from west to east after crossing the Andes and high-level troughs arising from the baroclinic instability of the westerlies [141][142][143][144][145][146][147]. The jet stream position and occurrence of potential vorticity streamers also contribute to a more baroclinic environment in the region, especially in the summer [147].…”

“…Additionally, southeastern R3 is located near a cyclogenesis hotspot, around 35 • S in Uruguay [141][142][143][144][145][146]. Some aspects contributing to this feature include the westerlies' baroclinic instability, subtropical COLs crossing the continent, the lee effect induced by the Andes, and moisture transport from Amazon by SALLJ [141,143].…”

“…O setor sudoeste do oceano Atlântico Sul (OAS) é um local propício à gênese de ciclones extratropicais (Gan & Rao, 1991;Hoskins & Hodges, 2005;Reboita et al, 2010aReboita et al, , 2015Gramcianinov et al, 2020;Crespo et al, 2020;de Jesus et al, 2020) e subtropicais (Gozzo et al, 2014;Reboita et al, 2019a), mas não de ciclones tropicais (Gray, 1968;Reboita et al, 2020;da Rocha et al, 2019). Desde o início da era satelital, apenas dois ciclones tropicais foram registrados no OAS: o Catarina, em março de 2004, que se formou através de um processo de transição tropical (Pezza & Simmonds, 2005;McTaggart-Cowan et al, 2006) e o Iba, ocorrido em março de 2019 e considerado a primeira ciclogênese tropical pura nesse oceano (Reboita et al, 2020).…”
