Figure 5.2
Severe flooding in the Paraná drainage of northern Argentina and Uruguay can be seen in this early January 1998 view (NASA photograph NASA6-710-077). The photo looks west over the Rio Meriñay (foreground) and the Paraná (under the solar panel). Sunglint highlights the immense area covered in water - the edges of the normal river drainages can barely be discerned in the larger flooded river valleys (arrows). Salto, Uruguay is just off the edge of the image to the lower left. The graph shows the regional precipitation deviations due to El Niño. The cumulative observed precipitation is given by the heavy solid line, and normal precipitation (cumulative) is depicted by the thin dashed line. The bar indicates when the photo was taken.
