Classificação dos tipo de tempo em Belo Horizonte - MG

Abstract

The understanding of atmospheric dynamics and its interaction with surface factors, at different spatiotemporal scales, directly influences meteorological weather conditions and local climate organization. The effects of such interactions appear in the variation of climatic attributes and can positively and negatively impact human activities and natural processes. The objective of this research proposal is be to establish a classification of weather types that are representative of the local climate reality where the urban area of Belo Horizonte is located, with reference to the year 2020 (rainy year). The methodological procedures will include (1) survey of bibliographic sources and meteorological data, (2) organization and statistical analysis of data from automatic and conventional meteorological stations (INMET), (3) analysis of synoptic charts (Marinha do Brasil) and images collected from meteorological satellite (DSA/INPE), (4) application of rhythmic analysis as a basic methodology for analysis of multi-scale integration, and (5) classification of types of time. The result of the research consisted in the creation/classification of 18 types of time that were divided into 3 macro categories, indicative of the general state of the atmosphere over Belo Horizonte, with weather types classified as unstable, stable and transient.
