Geostatistical surfaces of climatological normals of mean air temperature in Minas Gerais.

Air temperature, a vital component for the terrestrial environment sustainability, can be used as an indicator and an important factor used in short- and long-term meteorological modeling at different scales. Temperature must be monitored on spatial and temporal scale with high precision. Terrain elevation can be used as the main influence factor depending on the measurement scale.

Human progress and drought sensitivity behavior.

Objectives: Human progress is the satisfaction of human needs associated with life quality, social and economic justice. Considering that climate had significant effect on socio-economic behavior of Earth populations, the objective of this work was to evaluate the relationship between human progress and drought sensitivity behavior in Minas Gerais State, Brazil.

Methods: The human progress variable was generated by principal component analysis, considering the factors: Territorial occupation of the population, dependency ratio, urbanization degree, income, habitation, health, education, sanitation, security and human development index.
