Abstract

MARQUES, José; SANTOS, Jesus Marden dos; VILLA NOVA, Nilson Augusto  and  SALATI, Eneas. Precipitable water and water vapor flux between Belém and Manaus(). Acta Amaz. [online]. 1977, vol.7, n.3, pp.355-362. ISSN 0044-5967.  https://doi.org/10.1590/1809-43921977073355.

The water vapor flux and precipitable water was computated over the natural Amazon forest in the stretch between Belem and Manaus for 1972. The atmospheric branch of hidrological cycle teory was applied and the most significant conclusions on an annual basis are: Atlantic Ocean water vapor contributes 52% to the regional precipitation and is significant the role played by local evapotranspiration in the precipitation in the area; there were signs of the phenomenon of water vapor recycling nearly throughout the year. Evapotranspiration contribute to 48% of the precipitations in the area studied. The real evapotranspiration estimated by this method was 1,000mm year-1.
