Characteristics of Amazonian climate: main features

This chapter summarizes our current knowledge on the mean climatological features ofAmazonia. Significant uncertainties remain in our understanding ofthe complex dynamics of climate and climate variability in that region, which are due, in part, to the lack of observational data. The strong seasonal...

Understanding the climate of Amazonia: progress from LBA

The Amazon plays an important role in the functioning of the Earth's climate. It acts as one ofthe critical heat sources for the global atmosphere via evaporation of water vapor at the surface and release ofheat in the middle and upper troposphere by latent heat of condensation in tropical convectiv...

Ecophysiology of forest and savanna vegetation

Ecophysiological characteristics of forest and savanna vegetation are compared in an attempt to understand how physiological differences within and between these vegetation types relate to their geographical distributions. A simple ordination first shows that although precipitation exerts a key effe...

The Amazonian boundary layer and mesoscale circulations

The interactions between the Amazonian boundary layer, the surface, atmospheric convection, aerosols, and larger-scale circulations are complex. The field experiments inAmazonia have provided rich insights into the daytime and nighttime boundary layer in different regions and seasons over both fores...
