Resumen

El presente artículo aborda el análisis de las series históricas de precipitación en la Cuenca Hidrográfica del Camaquã (BHC), ubicada en Rio Grande do Sul, Brasil. El estudio destaca la relevancia del monitoreo climático, especialmente para entender las variaciones en la precipitación, que impactan en actividades económicas locales como la agricultura y la ganadería. El objetivo principal es identificar y llenar las brechas en los datos históricos de precipitación, utilizando métodos estadísticos como la regresión lineal múltiple, y verificar las tendencias de precipitación a lo largo de 40 años (1981-2020). La investigación también correlaciona datos históricos con el reanálisis, con el fin de evaluar la precisión de este modelo. Los resultados indican una distribución media casi homogénea a lo largo de los meses, con valores ligeramente superiores en la primavera. La serie histórica no mostró tendencias significativas. Cabe destacar que el ERA5 presenta una fuerte correlación con los datos observados, aunque tiende a sobreestimar la precipitación, especialmente en los meses más cálidos.
