AbstractThis study presents a 9-year climatology and composite analysis of quasi-linearconvective systems (QLCSs) in southern Brazil (SB). QLCSs are identified usingradar imagery and defined as a 100-km long, 40-dBZ convective line that lasts forat least 1 hr. QLCS cases associated with at least three severe wind reports are clas-sified as severe. Composites of the synoptic-scale environments and severe convec-tive weather parameters are constructed for severe and non-severe cases of threesynoptic patterns found as the most recurrent in QLCS cases. QLCSs are more fre-quent and more likely to be severe during spring, while very few cases occur dur-ing winter. Most cases occur during late night and morning, corroborating previousresearch of mesoscale convective systems in this area, but the percentages of severecases are higher in late afternoon and early night. Faster QLCSs, particularly thosewith velocities greater than 50 km/hr, have higher probability of being severe incomparison to slower systems. The three synoptic patterns more often related toQLCS occurrence in SB are characterized by a mid-level trough upstream of SB(type 1), a mid-level trough west of the Andes (type 2) and predominance of zonalflow over SB (type 3). In general, there is a low-pressure system over northwesternArgentina extending a trough to SB, where low-level moisture flux convergenceand warm advection occur. In severe cases, the sea-level pressure is lower in north-western Argentina and there is greater low-level northwesterly flow over SB. Thetype 1 is the most frequent pattern when QLCSs are observed in SB and is also thetype with higher percentage of severe cases. Convective available potential energy(CAPE) and downdraft CAPE are good discriminators between severe and non-severe cases in type 1 and 2 environments, while the 1,000500-hPa bulk wind dif-ference is a better predictor in type 3 cases.
