Resumo:
The quantification of radiation and energy exchanges in most vegetated surfaces is essential for better understanding of the functioning of the systems and to assess possible changes in the interaction between these and atmosphere, on the partition of energy. The present work had as purpose to analyze the radiation balance components measured and estimated and analyze the energy balance components obtained by reason of Bowen. The study carry out on a mango Orchard (Mangifera indica L.) Tommy Atkins variety, located in the northeastern region of Pará, situated in the village of Cuiarana (00°39´47' S; 47°17´48" W). The data were measured on a micrometeorological Tower and the quarterly analyses are for the year of 2013. The results showed that the values of the measured and estimated radiation balance showed high correlation in quarters analyzed with maximum (R2 = 0, 96) and minimum (R2 = 0, 94). Compared with the estimated radiation balance values were superior to the balance of radiation measured observed in every year. As for the energy balance components estimated by Bowen ratio technique, showed that the largest percentage of the radiation balance in the orchard was used in the form of latent heat, during the entire year of study and showed variation of 80.6% observed during the rainy season (Jan-Feb-Mar) to 62.25% registered in the dry season (Oct-Nov-Dec). On the other hand, the heat sensitive showed increased 17.41% observed during the rainy season, to 38.23% in the dry period.
