Abstract

Episódios de seca estão se tornando cada vez mais comuns atualmente no cenário de mudanças climáticas. Desta forma, o objetivo desta pesquisa foi analisar a variabilidade de precipitação e a probabilidade de ocorrência de veranico na Mesorregião Centro Ocidental Paranaense. Como objetivo secundário, analisou-se a ocorrência de um veranico extremo no mês de setembro de 2020. Para isso, foram criados mapas com interpolações para regionalizar as alturas pluviométricas. Criou-se gráficos de box plot e probabilidades para identificar o comportamento pluviométrico regional, além da análise gráfica e sinótica das chuvas de setembro de 2020. A precipitação anual na Mesorregião apresentou distribuição considerável anual e mensal, com valores médios que mostram extrato do balanço hídrico todo positivo. Porém, a região possui grande variabilidade e amplitude de mais de 500mm entre os meses mais chuvosos e mais secos. Na ocorrência de períodos secos, também se identificou valores alarmantes, com agosto apresentando até 60% de probabilidade de veranicos. Reflexo dessa grande variabilidade ocorreu em 2020, cuja série de dados maior que 40 anos, apresentou o mês de setembro mais seco da história.

I am an Agronomist Engineer graduated from the State University of Londrina (UEL), between the years 2008 to 2012, approved in the first Selection Process (Vestibular) provided. I have experience in Plant Genetic Improvement, by IAPAR, an institution for which I worked as a Scientific Initiation Fellow, with Federal funding from PIBIC/CNPq, for the Project of Research characterization and conservation of Wheat Genetic Resources. At the end of the IC Fellowship, I received the ÓTIMO concept, the best IAPAR concept attributed to the fellow, for the quality of the Scientific Report and for the presentation at the XIX Seminar of the Program of Scientific Initiation of the Work, entitled "Characterization, Conservation and Pre-improvement of Wheat Genetic Resources in the Agronomic Institute of Paraná (IAPAR)". I have experience in conducting fieldwork, laboratories and Scientific Research. I have experience in the management and research of medicinal and aromatic plants, an area in which I developed the obligatory curricular internship and the Project of Course Conclusion, in Agronomy. I have converted classroom notes into a Technical Specialized Book with ISBN record, entitled "Special Topics in Agronomy", of 737 pages. Master in Conservationist Agriculture graduated from the Instituto Agronômico do Paraná (IAPAR), area of concentration in Conservationist Management of Natural Resources and Scholarship from the Coordination of Improvement of Higher Level Personnel (CAPES), for having been approved in the Master's Selection Process, in second place in the area of concentration. I have experience in University Teaching for Graduation in Agronomy at UNIFIL - Philadelphia University Center, the discipline of agrometeorology (Teaching Internship for CAPES Scholarship Students). In my Master's Dissertation, I worked with the effects of ENOS and ODP climatic phenomena on soybean productivity, in the western region of Paraná, being the dissertation part of the ITAIPU/IAPAR Project on Soybean Productivity around the ITAIPU Reservoir. I was guided by Paulo Henrique Caramori, one of the most exponent names in Agrometeorology in Brazil. After his master's degree, I was a Technical Fellow at Fundação Araucária, in the Project (ITAIPU/IAPAR) Monitoring of Hydro-Sedimentology in Micro-basins - North Paraná Mesoregion, from September 2017 to April 2018.
