Ritmo climático, a partir de aspectos da precipitação pluviométrica, na região metropolitana de Sorocaba, entre os anos de 2000 a 2015

Abstract

Study of the climate has evolved considerably throughout the years. In the climatic characterization of a locality, study the rhythm is important to know the dynamics on a certain scale, but also the interactions resulting from the movements that occur in the atmosphere.. The metropolitan region of Sorocaba was established in 2014, representing an intention of integration of some municipalities near Sorocaba. Later, in 2016, the municipality of Itapetininga was incorporated to this region The characterization of atmospheric phenomena can be realized by the Standard Years technique, wherever, from a given variable, the years are classified according to the similarities between these characteristics of atmospheric attributes, forming groups of years in common. With this characterization, it is possible to perform a rhythmic analysis of some periods within the selected interval. This work has as objective to establish the patterns and the spatio-temporal characteristics of rainfall in the Metropolitan Region of Sorocaba from the perspective of rhythmic analysis, between the years 2000 to 2015. For this purpose, we selected data from twenty pluviometers of DAEE present in the region, establishing the standard years. With this information, data from five weather stations were selected, being three from INMET and two from CIIAgro from January and July of 2009, 2013 and 2014. The use of Standard Deviation in relation to the mean to define the standard years in this area of study showed that there is a great diversity of characteristics to be watched in the Metropolitan Region of Sorocaba. Because of this, it is possible to observe that a certain year has characteristics of a rainy year in one location and another year in another location. In the rhythmic analyzes made in the Metropolitan Region of Sorocaba, it was possible to observe that each location presented different behaviors, even under the influence of the same atmospheric systems. Can contribute to it, factors such as altitude, vegetation, land use and the geographical location of the measurement site itself. These differentiations reinforce the transition aspect present in the RMS and show that it is important to know these characteristics in depth to properly understand the regional dynamics present.
