Ombrothermic diagram of the Camobi neighborhood, Santa Maria, RS for the period 2010 to 2017

Abstract

For the human activities development, the detailed knowledge of the climatic conditions is essential. However, in many fields, there is a lack of information about it ant the the environmental problems became larger with the human sedentarisation. These problems occur in several places due to planning deficiency, that is, lack in the natural resources management process. In the city of Santa Maria, RS, the conditions are exacerbated due to its particular location, a transition zone between the Pampa and the Atlantic Rainforest biomes. Aiming to enlarge the information available in the climatic and ecological fields, this paper establish ombrothermic diagrams and identifies the ombric and thermical monthly curves in the Camobi Neighborhood, in the municipality of Santa Maria, RS. The methodology followed was proposed from Bagnouls and Gaussen (1963). It were used data from 2010 to 2017. The monthly mean air temperature was 19,48ºC and the monthly mean precipitation was 145,99mm. The yearly mean precipitation was 1.752mm. It is concluded that, considering the monthly mean air temperature (ºC) and pluviometric precipitation (mm), there is no dry period in the Camobi neighbourhood. However, when yearly results are considered, dry periods are identified in 2010 between March and July, in 2011 in Dezember, in 2012 in March and Juky, in 2016 in June and in 2017 in July. It is also verified that, even in the most dry years, described as years with occurance of drought, the dry period happens in small intervals, such as in 2011, 2012 and 2016.
