Inter Seasonality of the Energy Fluxes in Brazilian Savana—Mato Grosso—Brazil

Dynamics of flows of matter and energy these biomes are relevant to understanding of environmental processes that govern the biosphere-atmosphere interactions and between ecosystems. This study analyzed inter season and season of energy fluxes in Brazilian Savana through Bowen Ration Method. Results show differences in patterns LE in all season, LE predominant in wet while H in dry. This inversion in patterns of predominant components of the energy balance in wet and dry season because in wet season increase water content in soil and atmosphere due precipitation in this season providing more lost energy for atmosphere in shape LE through soil evaporation and plant transpiration, this results in LE and H in all season of the Brazilian Savana show higher variation in dynamics energy fluxes between surface and atmosphere, as well as energy partition in this biome. Statistics analyses presents than many climate variables influences LE and H in each season indicating complexity in this fluxes. More study is necessary to higher understand patterns energies fluxes in Brazilian Savana.
