abstract = "This paper analyzes atmospheric conditions related to an extreme
rainfall event that reached Northern of Rio Grande do Sul (RS) in
July 10, 2007. Different data sources were used: rainfall daily
data from 16 meteorological surface stations of RS to verify the
rainfall registered on RS during the event; infra-red (channel 4)
satellite imagery from GOES 10 (Geostationary Operational
Environmental Satellite), to analyze the evolution of
meteorological system that generated the event; surface and
altitude synoptic charts from July 10, 2007 at 00 UTC to analyze
the meteorological systems acting on the RS and data from
NCEP-CFSR Reanalysis (National Centers for Environmental
Prediction - Climate Forecast System Reanalysis), to analyze the
large-scale environment associated with the event. The results
showed that the circulation in low-level of the atmosphere
contributed to supply the study area with large amount of heat and
humidity. This condition combined with the occurrence of Frontal
System observed from July 09, 2007 contributed to the organization
of atmospheric instability and convective cloudiness observed,
favoring the occurrence of the extreme rainfall registered in
Northern RS in July 10, 2007.",
