%X Due to the location in a subtropical region, Rio Grande do Sul state (RS) is under the influence of various meteorological phenomena capable of generating precipitation, among which stand out the Mesoescale Convective Systems (MCS). The MCS are defined as convective cloud clusters and are also responsible for most severe weather conditions in the RS. Hail is the most destructive of these events and cause direct impacts on the states economy, mainly focused on agrobusiness. Therefore the aim of this study was to evaluate the characteristics and impacts of MCS more frequents to affect RS from 2004 to 2008 and that have caused hail, using ForTrACC application, raw images from the GOES satellite and data from RS Civil Defense. Ten MCS of continental, diurnal and frontal origin (MCSHAIL-CDF) were analyzed and the results showed that MCSHAIL-CDF were formed mainly between the western RS and northeastern Argentina, but there were seasonal differences. Generally was observed preferential displacement to eastward, however with seasonal variations in relation to the predominant quadrant, northeastward in the cold months and southeastward in the warm months. In total 31 municipalities were hit by hail generated by the MCSHAIL-CDF between 2004 and 2008, and 10 of these reported damage in agriculture.
