Aspectos Climáticos Do Estado De Minas Gerais (Climate Aspects in Minas Gerais State)

Abstract

RESUMO:A caracterização do clima de um determinado local é um aspecto importante para vários setores da economia como, por exemplo, na prática agrícola. Diante disso, o objetivo desse estudo é apresentar alguns dos principais aspectos climáticos do estado de Minas Gerais (MG): precipitação, temperaturas mínima, média e máxima, intensidade e direção dos ventos a 10 metros de altura, classificação climática de Köppen-Geiger e índice de aridez. Para isso, se utilizaram dados de diferentes fontes. Entre os resultados têm-se que os maiores totais anuais de precipitação ocorrem no sul do estado; as temperaturas são influenciadas tanto pela latitude quanto pela topografia, com o setor sul de MG apresentando médias anuais de cerca de 20ºC e o norte de 26ºC; os ventos em escala sinótica são de direção nordeste a maior parte do ano; o clima Aw é dominante em MG, de acordo com a classificação de Köppen-Geiger; e, em relação ao índice de aridez, MG tem condições úmidas em toda sua área no verão e, predominantemente, áridas no inverno.

Thereby, the aim of this study is to present some major climatic aspects of Minas Gerais State (MG), Brazil: precipitation; minimum, mean and maximum air temperatures; winds intensity and direction at 10 meters height; Köppen-Geiger climate classification; and aridity index. For this, data of different sources were used. Among the results obtained are that the largest total annual precipitation occur in the south of state; the temperatures are influenced both by latitude as topography, with the southern sector showing annual means of about 20°C and 26°C in the northern sector; the winds at synoptic scale are of northeast direction most of the year; the Aw climate dominates MG, according to the Köppen-Geiger classification; and, in relation to the aridity index, MG has humid conditions in the whole area of the state in the summer and, predominantly, arid conditions in winter.

Cardinal temperatures and thermal requirements for the initial development of two Brazilian native species

“…Nonetheless, in the present study, atypical air temperatures were observed in the period of higher development for the two species, which corresponds to Sd11 and Sd12 (from March to September 2016), with T med values from 17.2 to 18.1ºC. These values are inferior to the climatic mean values of the studied region, which range from 20.1 to 21ºC (Reboita et al, 2015). This may have contributed to the lower-estimated optimum temperature values for both species.…”

Insights into the Positive Effect of Pyraclostrobin on Sugarcane Productivity

“…The soil of the experimental area has a clayey texture, and the climate of the region is classified as humid subtropical (Cwa), with a rainy season in the summer and a drought season in the winter [19]. Meteorological data (precipitation and temperature) during the experiment are presented in Figure 1.…”

Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)

“…The pilot study was conducted with three male greater rheas held by Belo Horizonte Zoo, Brazil (S 19°51' , W 44°01'): hereafter BH Zoo. The mean annual temperature varies between 18°C and 24°C, and the annual pluviometric mean of 1,460 mm, with two distinct seasons: a dry season from April to September and a rainy season from October to March, being the climate classified as Aw in the Köeppen system (Reboita et al, 2015). Birds were exposed to visitors six days a week (Tuesday to Sunday).…”
