The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface.The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapor in its atmosphere into ice clouds.
The Amazon River system is the single, largest source of freshwater on Earth and its flow regime is subject to interannual and long-term climate variability, which translate into large variations in downstream discharge (Richey et al., 1989; Marengo and Nobre, 2001; Marengo 2004, 2005, 2006, 2007; Milly et al., 2005, Marengo et al., 2008a, b; Cox et al., 2008; Zeng et al., 2008). To predict future climate (rainfall) change and consequent river variability an understanding of the physical mechanisms related to regional and large-scale atmospheric–oceanic–biospheric forcings is required.
