RELATIONSHIP OF NATURAL DISASTERS WITH MESOSCALE CONVECTIVE SYSTEMS THAT OCCUR IN SOUTHERN BRAZIL
Precipitation, MCS, Natural Disasters, Extreme Events.
Natural disasters are characterized as the result of adverse events, such as extreme precipitation or droughts, fires, landslides, among others, which in turn cause harm to humans, materials, and/or the environment, leading to both economic and social losses. In Brazil, there has been a growing increase in the number of disasters related to extreme precipitation, especially in the southern region of Brazil (SUB). One of the main triggers of such events are Mesoscale Convective Systems (MCS), which are responsible for a significant portion of the precipitation in this area. Given this context, the present study aims to correlate natural disasters with MCS that occur in the SUB. To conduct this study, data from the Forecast and Tracking the Evolution of Cloud Clusters (FORTRACC) will be used for MCS tracking, precipitation data from the National Institute of Meteorology (Inmet) and the National Center for Monitoring and Early Warning of Natural Disasters (CEMADEN), disaster-related information from the Integrated Disaster Information System (S2iD) and CEMADEN, soil moisture from the Soil Moisture Active Passive (SMAP), and reanalysis data from ERA5, in addition to statistical analysis. With this, we expect to obtain a positive correlation between disasters and MCS, physical and morphological information about MCS, and a characterization of the events that caused the disasters, as well as identifying areas more susceptible to disasters and the types of disasters.
