Identification of active meteorological systems in Santa Catarina with potential socioeconomic impact

Abstract

The article aims to comprehensively identify and analyze the meteorological systems operating in the State of Santa Catarina, Brazil, shedding light on their characteristics, scales of action, and associated impacts, particularly regarding socioeconomic impacts on society. Utilizing a bibliographic review, the study synthesizes knowledge about these systems, including their characteristics and scales. A total of 62 manuscripts were analyzed, revealing the complexity of climatic phenomena from interdecadal scales to mesoscales. It covers the Pacific Decadal Oscillation and El Niño, the Madden-Julian Oscillation, and the Antarctic Oscillation (Southern Annular Mode - SAM), cyclones, the South Atlantic Convergence Zone (SACZ), the South Atlantic Subtropical Anticyclone (South Atlantic High - SAH) and the South Pacific Subtropical Anticyclone (South Pacific High - SPH), Upper Tropospheric Cyclonic Vortex (UTCV), Weather Systems, and Jet Streams (both Upper-Level and Low-Level Jets), Mesoscale Convective Complexes, and Squall Lines. Although microscale phenomena were not specifically identified in the research, they represent a highly active scale of meteorological phenomena essential for understanding the fine interactions that affect the local climate, highlighting the impact of geographical characteristics and specific microclimatic variations in Santa Catarina. Integrating these scales of analysis and identifying the active systems in the State can contribute to the needs of various segments, especially those employing a holistic approach in meteorology, aiming for a better understanding and prediction of meteorological systems.
