abstract = "This study presents an analysis of a period with positive
precipitation anomalies and anomalous severe weather activity in
parts of the Southeastern Brazil during the dry season (austral
winter). The objectiveof this work is to identify the synoptic
pattern associated with the severe episodes on August 2018. The
analysis was based on observational data and the CFSR (Climate
Forecast System Reanalysis). Standardized anomalies of the main
meteorological variables were used in the analysis. An anomalous
trough in the mid and upper troposphere and the associated
low-level flow from the Amazon Basin to Southeastern Brazil
provided high amount of precipitable water, and were the main
responsible for the rainfall markedly above the climatology along
with severe hail and strong winds. The atmospheric environment was
conditionally unstable due to a stationary front. These type of
analyzes should be taken into consideration at this time of year
to improve weather forecasts and minimize impacts in such
circumstances.",
