Resumo: | The dry spells are characterized as the occurrence of consecutive days with no precipitation in the rainy season, which causes losses in agricultural crops. The present article aims to classify and regionalize the dry spells that occur during the rainy season, as well as to understand the possible consequences on crop losses. The study area was the state of Ceará, in which dry spells was defined as three or more consecutive days with daily precipitation equal to or less than 2 mm. From the IBGE yield data, it was calculated how the cultivation of corn and beans and the results can be inferred that: in the year considered rainy (2009), there was a smaller number of dry spells occurrences, but with losses significant crop losses due to excessive rainfall, mainly in the portions of the Litoral de Fortaleza and Litoral do Pecém. In the analysis of the dry years (1998 and 2012), there was a higher occurrence of dry spells and the losses of harvests even more intense, the dry spells indicator showed lower occurrences of events in the northwest of the state. The results indicate a probable indicator for classifying the consequences of a drought on rainfed agricultural production |

O presente artigo tem como objetivo classificar e regionalizar os veranicos que ocorrem durante a estação chuvosa, bem como, compreender as possíveis consequências sobre as perdas de safra. A área de estudo foi o estado Ceará, no qual os veranicos foram definidos como três ou mais dias consecutivos com precipitação diária igual ou inferior a 2 mm. A partir dos dados de rendimento do IBGE, foram calculadas as perdas do cultivo do milho e feijão, e através dos resultados pode-se inferir que: no ano considerado chuvoso (2009), foi verificada uma menor quantidade de ocorrências de veranicos, porém com perdas de safra significativas pelo excesso de chuvas, principalmente nas porções do Litoral de Fortaleza e Litoral do Pecém. Na análise dos anos secos (1998 e 2012), verificou-se maior ocorrência de veranicos e as perdas de safras ainda mais intensas, o indicador de veranicos apresentou menores ocorrências de eventos no noroeste do estado. Os resultados indicam um provável indicador para classificar as consequências de uma estiagem na produção agrícola de sequeiro.Revista Brasileira de Meteorologia2021-06-29T12:41:41Z2021-06-29T12:41:41Z2020info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfROCHA, Thaís Braga Carneiro; VASCONCELOS JUNIOR, Francisco das Chagas; SILVEIRA, Cleiton da Silva; MARTINS, Eduardo Sávio Passos Rodrigues; SILVA, Robson Franklin Vieira.Veranicos no Ceará e aplicações para agricultura de sequeiro.
