Resumo: The use of renewable sources has grown worldwide and in Brazil the incentive to use wind energy has been significantly expanded. The country's largest wind potential is concentrated in the Northeast (NE). The objective of this work is to measure the degree of regularity or predictability of wind velocity over Brazilian NE through the Sample Entropy method. The analyzes were carried out from the historical series of the ERA-40 reanalysis, arranged on a world grid with spatial resolution of 2,5° x 2,5° in records made at 10 m from the ground during the 00, 06, 12 and 18h during the period from 1957 to 2001. In addition to the four synoptic hours, daily, monthly and seasonal series were also generated. The results showed that the regions with higher wind speeds also present better predictability for the series. In addition, indicate that different areas with similar wind speed averages may have different predictability.

El mayor potencial eólico del país se concentra en el noreste (NE). El objetivo de este trabajo es medir el grado de regularidad o la previsibilidad de la velocidad del viento sobre el NE de Brasil a través del método de entropía de muestra de entropía. Los análisis se llevaron a cabo a partir de la serie histórica del reanálisis ERA-40, organizados en una cuadrícula mundial con resolución espacial de 2.5 ° × 2.5 ° en registros realizados a 10 m del suelo durante 00, 06, 12, 18h durante el período de 1957 a 2001. Además de las cuatro horas sinópticas, también se generaron series diarias, mensuales y estacionales. Los resultados mostraron que las regiones con mayor velocidad del viento también tienen una mejor previsibilidad para la serie. Además, suponen que diferentes áreas con promedios de velocidad del viento similares pueden tener una previsibilidad diferente.O uso de fontes renováveis tem crescido mundialmente e, no Brasil o incentivo ao uso de energia eólica tem sido ampliado de forma expressiva. O maior potencial eólico do país concentra-se no Nordeste (NE). O objetivo deste trabalho é medir o grau de regularidade ou a previsibilidade da velocidade do vento sobre o NE do Brasil através do método de entropia Sample Entropy. As análises foram realizadas a partir das séries históricas da reanálise ERA-40, disposta sobre uma grade mundial com resolução espacial de 2,5°× 2,5° em registros realizados a 10 m do solo durante as 00, 06, 12 e 18h durante o período de 1957 a 2001. Além das quatro horas sinóticas, foram também geradas séries diárias, mensais e sazonais. Os resultados mostraram que as regiões de maior velocidade do vento também apresentam melhor previsibilidades para as séries. Além de indicar que áreas distintas com comportamento das médias da velocidade do vento semelhantes podem apresentar previsibilidade diferentes.Research, Society and Development2020-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/474610.33448/rsd-v9i7.4746Research, Society and Development; Vol. 9 No. 7; e762974746Research, Society and Development; Vol. 9 Núm. 7; e762974746Research, Society and Development; v. 9 n. 7; e7629747462525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/4746/4173Copyright (c) 2020 Lêda Valéria Ramos Santana, Tatijana Stosic, Tiago Alessandro Espínola Ferreira, Antonio Samuel Alves da Silvainfo:eu-repo/semantics/openAccessSantana, Lêda Valéria RamosStosic, TatijanaFerreira, Tiago Alessandro EspínolaSilva, Antonio Samuel Alves da2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4746Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:29.536010Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
