Classificação Climática de Köppen-Geiger para o Estado de Goiás e o Distrito Federal

Abstract

O clima exerce importante influência quanto à disposição na qual o espaço se apresenta e é um dos elementos mais importantes na variação e transformação do mesmo. Esse estudo teve como objetivo classificar o clima no Estado de Goiás e no Distrito Federal utilizando a metodologia de classificação proposta por Köppen-Geiger (1900) e adaptada por Setzer (1966). Os elementos climáticos analisados foram a precipitação pluviométrica e a temperatura do ar com dados adquiridos de 104 estações pluviométricas (ANA) e 48 meteorológicas (INMET), respectivamente. Esses dados foram especializados utilizando o método de interpolação Topo to Raster manipulados em um ambiente de SIG. Em relação aos dados de temperatura foi possível perceber que a região mais quente do Estado de Goiás é a Noroeste, enquanto a de temperatura mais amena é uma região localizada entre os municípios de Goiânia e Anápolis. Quanto à precipitação pluviométrica, as regiões com maior volume de chuva foram a região central do Norte goiano e no município de Piracanjuba, no Sudeste do Estado de Goiás. Foram identificados o Estado de Goiás quatro tipos de clima: Am, Aw, Cwa e Cwb, enquanto para o Distrito Federal apenas um tipo de clima foi identificado, o Aw.

Arbuscular mycorrhizal fungi in the soil using cover crops with and without nitrogen addition

“…This finding can be explained by the seasonal characteristics of the region where the plants were grown. The Cerrado is a region that has two well-defined climatic seasons, the dry season and the rainy season (Cardoso et al, 2015). The behavior of mycorrhizal fungi in Cerrado soils is closely linked to this seasonal variation (Vieira Junior et al, 2020).…”

“…The evaluations were carried out in the agricultural years 2009/2010 and 2010/2011. The chemical analysis of the soil collected in the 0-10 cm depth layer at the end of the 2010/2011 agricultural year, according to Claessen (1997), presented the following results: pH 5.9 in H2O; 26.3 g kg −1 organic matter; 8.3 mg dm 3 of P-Mehlich1; 0.07 cmolc dm 3 of Al; 3.6 cmolc dm 3 ca + mg; and 0.2 cmolc dm 3 of K. The climate is classified as a tropical station, Aw, according to Köppen, and is characterized by two well-defined seasons (dry and rainy) and the occurrence of periods of drought during the rainy season (Cardoso et al, 2015). In April 2010, the following plant species were sown in the area for soil cover: Crotalaria juncea (Crotalaria juncea L.), cearaẃ ild beans (Canavalia brasiliensis Mart.…”

Reinoculation of topdressing Rhizobium tropici combined or not with Azospirillum brasilense in common bean

“…The soil of the area is classified as a Typic Hapludox (USDA 2014), or Latossolo Vermelho-Amarelo Distroférrico (Santos et al 2018) of sandy loam texture. The climate of the region is Aw, according to the Köppen classification, with monthly temperatures higher than 20 ºC and annual rainfall of 1,100-1,800 mm (Cardoso et al 2014). The maximum temperature recorded during the experiment was 34.9 ºC, while the minimum was 13.2 ºC.…”

Boron and Zinc Fertilizer Application to Maize Crops in a Lithic Quartzipsamment

“…The soil used was classified as Lithic Quartzipsamment (Neossolo Litolico distrofico;SANTOS et al, 2018), with predominance of quartzose gravel (2.0 the 20.0 mm); the chemical attributes and granulometric composition are presented in Table 1 (TEIXEIRA et al, 2017). The climate of the region is Aw, tropical with two well-defined seasons (dry and rainy seasons), according to classification of Köppen (1900) adapted by Cardoso, Marcuzzo, and Barros (2015). The dry season encompasses five months; the mean annual temperature is 24 ºC and the mean annual rainfall depth is 1,613 mm.…”
