| Abstract | An intense Mesoscale Convective System (MCS) that occurred in Southern South America between 29 and 30 November 2009 was analyzed in this study. The choice of this system was because severe weather conditions related to its occurred. In some areas of state of Rio Grande do Sul-Brazil, winds of the order of 100 km/h and precipitation higher than 50 mm in 24 hours was observed, causing serious damages in several cities. The dataset from the ERA-Interim reanalysis, with spatial resolution of 1.5 ° x1, 5 ° lat/lon, was used to generate meteorological fields in order to analyze the synoptic situation associated with the formation of the MCS. The MCS was simulated using the Coupled Aerosol and Tracer Transport model to the Brazilian Developments on the Regional Atmospheric Modeling System (CCATT-BRAMS) with 15 km spatial resolution and 38 vertical levels, and outputs each 1h. To analyze the simulated precipitation fields, we used a precipitation field generated with observational data of raingauge network from several Brazilian institutions (http://clima1.cptec.inpe.br). According to data from the reanalysis and satellite pictures, the MCS was associated with a cold front. We observed the presence of a low pressure center in northwest Argentina positioned at west of the MCS. Moreover, it was found that the system formed downstream of a Low Level Jet (LLJ) at east of the Andes. Strong warm and moist advection in the layer between the surface and 850 hPa, associated with the dowstream JBN, toward the western region of Rio Grande do Sul were found, where we observed the occurrence of maximum precipitation. In upper levels, the presence of the jet stream contributed to the formation/intensification of MSC, since this system was observed at the entrance of the equatorial jet stream at high levels. The CCATT-BRAMS simulated the major features observed in synoptic fields generated with the reanalysis. However, it was found that the axis of LLJ was shifted to the northwest, over the eastern region of Paraguay. Thus, the downstream LLJ was verified over state of Parana. When we compared the simulation of accumulated precipitation and observed precipitation, it was found that the model shifted the maximum rainfall occurred west of Rio Grande do Sul to Paraguay, possibly due to the displacement of the LLJ for this region. |
