Energy balance in the Cerrado of Ecological Station of Assis – Assis, São Paulo State, Brazil

Edson Xavier Fernandes, Jonas Teixeira Nery

Resumo


This article presents the results of the net radiation partitioning (Rn) between latent heat (LE) and sensible heat fluxes (H) and its relationship with water availability (rain) in an area with Cerrado vegetation in the state São Paulo, Brazil. Heat fluxes follow the energy standard available in the environment, with higher values during the rainy season and lower values in the dry season. However, in the dry season, increased sensible heat flux over the latent heat flux was observed, which could be due to the lower water availability in the environment. Similar studies that have examined the dynamics of natural systems can contribute to the development of public policies for preservation and conservation of natural resources in a context in which the man-nature relationship is marked by imbalances in view of the form of use of natural resources based on predatory model adopted by society over the past 200 years.
