                         existence of three different nighttime turbulent regimes observed 
                         in the Amazon forest, classified according to Sun's criteria: 
                         regime 1: weak turbulence, low wind speed; regime 2: strong 
                         turbulence, with high wind speed, and regime 3: intermittent 
                         turbulence events. Next, we have investigated some of the main 
                         statistical characteristics of turbulent regimes. In situations 
                         with strong winds and high values of turbulent kinetic energy (4% 
                         of cases) sensible heat fluxes are about 40 times higher than the 
                         ones under light winds and low turbulent kinetic energy values 
                         (95% of cases). Furthermore, the inflection point height in the 
                         wind profile and shear length scale L-h = u(h)/(du/dz) (where u(h) 
                         is the mean wind velocity at canopy top) increases with the regime 
                         2, with the occurrence of strong mixing in the atmospheric 
                         boundary layer. In addition the coherent structure time scale in 
                         the regime 2 is greater than regime I. Regime 3 is essentially
